You can specify various properties - that your computed property is dependent on. This will force the cached - result to be recomputed if the dependencies are modified. - - In the following example we declare a computed property (by calling - `.property()` on the fullName function) and setup the properties - dependencies (depending on firstName and lastName). The fullName function - will be called once (regardless of how many times it is accessed) as long - as it's dependencies have not been changed. Once firstName or lastName are updated - any future calls (or anything bound) to fullName will incorporate the new - values. - - ```javascript - Person = Ember.Object.extend({ - // these will be supplied by `create` - firstName: null, - lastName: null, - - fullName: function() { - var firstName = this.get('firstName'); - var lastName = this.get('lastName'); - - return firstName + ' ' + lastName; - }.property('firstName', 'lastName') - }); - - var tom = Person.create({ - firstName: "Tom", - lastName: "Dale" - }); - - tom.get('fullName') // "Tom Dale" - ``` - - You can also define what Ember should do when setting a computed property. - If you try to set a computed property, it will be invoked with the key and - value you want to set it to.

The value of this property should be a string representing a path - to another object or a custom binding instanced created using Binding helpers - (see "One Way Bindings"): - - ``` - valueBinding: "MyApp.someController.title" - ``` - - This will create a binding from `MyApp.someController.title` to the `value` - property of your object instance automatically. Now the two values will be - kept in sync. - - ## One Way Bindings - - One especially useful binding customization you can use is the `oneWay()` - helper. This helper tells Ember that you are only interested in - receiving changes on the object you are binding from. For example, if you - are binding to a preference and you want to be notified if the preference - has changed, but your object will not be changing the preference itself, you - could do: - - ``` - bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles") - ``` - - This way if the value of `MyApp.preferencesController.bigTitles` changes the - `bigTitles` property of your object will change also. However, if you - change the value of your `bigTitles` property, it will not update the - `preferencesController`. - - One way bindings are almost twice as fast to setup and twice as fast to - execute because the binding only has to worry about changes to one side. - - You should consider using one way bindings anytime you have an object that - may be created frequently and you do not intend to change a property; only - to monitor it for changes (such as in the example above). - - ## Adding Bindings Manually - - All of the examples above show you how to configure a custom binding, but the - result of these customizations will be a binding template, not a fully active - Binding instance. The binding will actually become active only when you - instantiate the object the binding belongs to. It is useful however, to - understand what actually happens when the binding is activated. - - For a binding to function it must have at least a `from` property and a `to` - property. The `from` property path points to the object/key that you want to - bind from while the `to` path points to the object/key you want to bind to. - - When you define a custom binding, you are usually describing the property - you want to bind from (such as `MyApp.someController.value` in the examples - above). When your object is created, it will automatically assign the value - you want to bind `to` based on the name of your binding key. In the - examples above, during init, Ember objects will effectively call - something like this on your binding: - - ```javascript - binding = Ember.Binding.from(this.valueBinding).to("value"); - ``` - - This creates a new binding instance based on the template you provide, and - sets the to path to the `value` property of the new object. Now that the - binding is fully configured with a `from` and a `to`, it simply needs to be - connected to become active. This is done through the `connect()` method: - - ```javascript - binding.connect(this); - ``` - - Note that when you connect a binding you pass the object you want it to be - connected to. This object will be used as the root for both the from and - to side of the binding when inspecting relative paths. This allows the - binding to be automatically inherited by subclassed objects as well. - - Now that the binding is connected, it will observe both the from and to side - and relay changes. - - If you ever needed to do so (you almost never will, but it is useful to - understand this anyway), you could manually create an active binding by - using the `Ember.bind()` helper method. (This is the same method used by - to setup your bindings on objects): - - ```javascript - Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value"); - ``` - - Both of these code fragments have the same effect as doing the most friendly - form of binding creation like so: - - ```javascript - MyApp.anotherObject = Ember.Object.create({ - valueBinding: "MyApp.someController.value", - - // OTHER CODE FOR THIS OBJECT... - }); - ``` - - Ember's built in binding creation method makes it easy to automatically - create bindings for you. You should always use the highest-level APIs - available, even if you understand how it works underneath. - - @class Binding - @namespace Ember - @since Ember 0.9 -*/ -Ember.Binding = Binding; - - -/** - Global helper method to create a new binding.

The - primary way of interacting with a promise is through its `then` method, which - registers callbacks to receive either a promise’s eventual value or the reason - why the promise cannot be fulfilled. - - Terminology - ----------- - - - `promise` is an object or function with a `then` method whose behavior conforms to this specification. - - `thenable` is an object or function that defines a `then` method. - - `value` is any legal JavaScript value (including undefined, a thenable, or a promise). - - `exception` is a value that is thrown using the throw statement. - - `reason` is a value that indicates why a promise was rejected. - - `settled` the final resting state of a promise, fulfilled or rejected. - - A promise can be in one of three states: pending, fulfilled, or rejected. - - Promises that are fulfilled have a fulfillment value and are in the fulfilled - state. Promises that are rejected have a rejection reason and are in the - rejected state. A fulfillment value is never a thenable. Similarly, a - rejection reason is never a thenable. - - Promises can also be said to *resolve* a value. If this value is also a - promise, then the original promise's settled state will match the value's - settled state. So a promise that *resolves* a promise that rejects will - itself reject, and a promise that *resolves* a promise that fulfills will - itself fulfill. - - - Basic Usage: - ------------ - - ```js - var promise = new Promise(function(resolve, reject) { - // on success - resolve(value); - - // on failure - reject(reason); - }); - - promise.then(function(value) { - // on fulfillment - }, function(reason) { - // on rejection - }); - ``` - - Advanced Usage: - --------------- - - Promises shine when abstracting away asynchronous interactions such as - `XMLHttpRequest`s. - - ```js - function getJSON(url) { - return new Promise(function(resolve, reject){ - var xhr = new XMLHttpRequest(); - - xhr.open('GET', url); - xhr.onreadystatechange = handler; - xhr.responseType = 'json'; - xhr.setRequestHeader('Accept', 'application/json'); - xhr.send(); - - function handler() { - if (this.readyState === this.DONE) { - if (this.status === 200) { - resolve(this.response); - } else { - reject(new Error("getJSON: `" + url + "` failed with status: [" + this.status + "]"); - } - } - }; - }); - } - - getJSON('/posts.json').then(function(json) { - // on fulfillment - }, function(reason) { - // on rejection - }); - ``` - - Unlike callbacks, promises are great composable primitives. - - ```js - Promise.all([ - getJSON('/posts'), - getJSON('/comments') - ]).then(function(values){ - values[0] // => postsJSON - values[1] // => commentsJSON - - return values; - }); - ``` - - @class RSVP.Promise - @param {function} - @param {String} label optional string for labeling the promise. - Useful for tooling. - @constructor - */ - function Promise(resolver, label) { - if (!isFunction(resolver)) { - throw new TypeError('You must pass a resolver function as the first argument to the promise constructor'); - } - - if (!(this instanceof Promise)) { - throw new TypeError("Failed to construct 'Promise': Please use the 'new' operator, this object constructor cannot be called as a function."); - } - - this._id = counter++; - this._label = label; - this._subscribers = []; - - if (config.instrument) { - instrument('created', this); - } - - if (noop !== resolver) { - invokeResolver(resolver, this); - } - } - - function invokeResolver(resolver, promise) { - function resolvePromise(value) { - resolve(promise, value); - } - - function rejectPromise(reason) { - reject(promise, reason); - } - - try { - resolver(resolvePromise, rejectPromise); - } catch(e) { - rejectPromise(e); - } - } - - Promise.cast = cast; - Promise.all = all; - Promise.race = race; - Promise.resolve = Resolve; - Promise.reject = Reject; - - var PENDING = void 0; - var SEALED = 0; - var FULFILLED = 1; - var REJECTED = 2; - - function subscribe(parent, child, onFulfillment, onRejection) { - var subscribers = parent._subscribers; - var length = subscribers.length; - - subscribers[length] = child; - subscribers[length + FULFILLED] = onFulfillment; - subscribers[length + REJECTED] = onRejection; - } - - function publish(promise, settled) { - var child, callback, subscribers = promise._subscribers, detail = promise._detail; - - if (config.instrument) { - instrument(settled === FULFILLED ?

This second, "downstream" - promise is resolved with the return value of the first promise's fulfillment - or rejection handler, or rejected if the handler throws an exception. - - ```js - findUser().then(function (user) { - return user.name; - }, function (reason) { - return "default name"; - }).then(function (userName) { - // If `findUser` fulfilled, `userName` will be the user's name, otherwise it - // will be `"default name"` - }); - - findUser().then(function (user) { - throw new Error("Found user, but still unhappy"); - }, function (reason) { - throw new Error("`findUser` rejected and we're unhappy"); - }).then(function (value) { - // never reached - }, function (reason) { - // if `findUser` fulfilled, `reason` will be "Found user, but still unhappy". - // If `findUser` rejected, `reason` will be "`findUser` rejected and we're unhappy". - }); - ``` - If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream. - - ```js - findUser().then(function (user) { - throw new PedagogicalException("Upstream error"); - }).then(function (value) { - // never reached - }).then(function (value) { - // never reached - }, function (reason) { - // The `PedgagocialException` is propagated all the way down to here - }); - ``` - - Assimilation - ------------ - - Sometimes the value you want to propagate to a downstream promise can only be - retrieved asynchronously. This can be achieved by returning a promise in the - fulfillment or rejection handler. The downstream promise will then be pending - until the returned promise is settled. This is called *assimilation*. - - ```js - findUser().then(function (user) { - return findCommentsByAuthor(user); - }).then(function (comments) { - // The user's comments are now available - }); - ``` - - If the assimliated promise rejects, then the downstream promise will also reject. - - ```js - findUser().then(function (user) { - return findCommentsByAuthor(user);

However, there are some cases where it is preferable - to build up a property's value by combining the superclass' property - value with the subclass' value. An example of this in use within Ember - is the `classNames` property of `Ember.View`. - - Here is some sample code showing the difference between a concatenated - property and a normal one: - - ```javascript - App.BarView = Ember.View.extend({ - someNonConcatenatedProperty: ['bar'], - classNames: ['bar'] - }); - - App.FooBarView = App.BarView.extend({ - someNonConcatenatedProperty: ['foo'], - classNames: ['foo'], - }); - - var fooBarView = App.FooBarView.create(); - fooBarView.get('someNonConcatenatedProperty'); // ['foo'] - fooBarView.get('classNames'); // ['ember-view', 'bar', 'foo'] - ``` - - This behavior extends to object creation as well. Continuing the - above example: - - ```javascript - var view = App.FooBarView.create({ - someNonConcatenatedProperty: ['baz'], - classNames: ['baz'] - }) - view.get('someNonConcatenatedProperty'); // ['baz'] - view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz'] - ``` - Adding a single property that is not an array will just add it in the array: - - ```javascript - var view = App.FooBarView.create({ - classNames: 'baz' - }) - view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz'] - ``` - - Using the `concatenatedProperties` property, we can tell to Ember that mix - the content of the properties. - - In `Ember.View` the `classNameBindings` and `attributeBindings` properties - are also concatenated, in addition to `classNames`. - - This feature is available for you to use throughout the Ember object model, - although typical app developers are likely to use it infrequently.

If this property is a function the result of calling - the function will be used as the initial value. This property is required. - - `initialize` - An optional initialize function. Typically this will be used - to set up state on the instanceMeta object. - - `removedItem` - A function that is called each time an element is removed - from the array. - - `addedItem` - A function that is called each time an element is added to - the array. - - - The `initialize` function has the following signature: - - ```javascript - function (initialValue, changeMeta, instanceMeta) - ``` - - `initialValue` - The value of the `initialValue` property from the - options object. - - `changeMeta` - An object which contains meta information about the - computed. It contains the following properties: - - - `property` the computed property - - `propertyName` the name of the property on the object - - `instanceMeta` - An object that can be used to store meta - information needed for calculating your computed. For example a - unique computed might use this to store the number of times a given - element is found in the dependent array. - - - The `removedItem` and `addedItem` functions both have the following signature: - - ```javascript - function (accumulatedValue, item, changeMeta, instanceMeta) - ``` - - `accumulatedValue` - The value returned from the last time - `removedItem` or `addedItem` was called or `initialValue`. - - `item` - the element added or removed from the array - - `changeMeta` - An object which contains meta information about the - change. It contains the following properties: - - - `property` the computed property - - `propertyName` the name of the property on the object - - `index` the index of the added or removed item - - `item` the added or removed item: this is exactly the same as - the second arg - - `arrayChanged` the array that triggered the change. Can be - useful when depending on multiple arrays. - - For property changes triggered on an item property change (when - depKey is something like `someArray.@each.someProperty`), - `changeMeta` will also contain the following property: - - - `previousValues` an object whose keys are the properties that changed on - the item, and whose values are the item's previous values. - - `previousValues` is important Ember coalesces item property changes via - Ember.run.once. This means that by the time removedItem gets called, item has - the new values, but you may need the previous value (eg for sorting & - filtering). - - `instanceMeta` - An object that can be used to store meta - information needed for calculating your computed. For example a - unique computed might use this to store the number of times a given - element is found in the dependent array. - - The `removedItem` and `addedItem` functions should return the accumulated - value. It is acceptable to not return anything (ie return undefined) - to invalidate the computation. This is generally not a good idea for - arrayComputed but it's used in eg max and min. - - Note that observers will be fired if either of these functions return a value - that differs from the accumulated value. When returning an object that - mutates in response to array changes, for example an array that maps - everything from some other array (see `Ember.computed.map`), it is usually - important that the *same* array be returned to avoid accidentally triggering observers. - - Example - - ```javascript - Ember.computed.max = function (dependentKey) { - return Ember.reduceComputed(dependentKey, { - initialValue: -Infinity, - - addedItem: function (accumulatedValue, item, changeMeta, instanceMeta) { - return Math.max(accumulatedValue, item); - }, - - removedItem: function (accumulatedValue, item, changeMeta, instanceMeta) { - if (item < accumulatedValue) { - return accumulatedValue; - } - } - }); - }; - ``` - - Dependent keys may refer to `@this` to observe changes to the object itself, - which must be array-like, rather than a property of the object. This is - mostly useful for array proxies, to ensure objects are retrieved via - `objectAtContent`. This is how you could sort items by properties defined on an item controller. - - Example - - ```javascript - App.PeopleController = Ember.ArrayController.extend({ - itemController: 'person', - - sortedPeople: Ember.computed.sort('@this.@each.reversedName', function(personA, personB) { - // `reversedName` isn't defined on Person, but we have access to it via - // the item controller App.PersonController. If we'd used - // `content.@each.reversedName` above, we would be getting the objects - // directly and not have access to `reversedName`. - // - var reversedNameA = get(personA, 'reversedName'), - reversedNameB = get(personB, 'reversedName'); - - return Ember.compare(reversedNameA, reversedNameB); - }) - }); - - App.PersonController = Ember.ObjectController.extend({ - reversedName: function () { - return reverse(get(this, 'name')); - }.property('name') - }) - ``` - - Dependent keys whose values are not arrays are treated as regular - dependencies: when they change, the computed property is completely - recalculated. It is sometimes useful to have dependent arrays with similar - semantics. Dependent keys which end in `.[]` do not use "one at a time" - semantics. When an item is added or removed from such a dependency, the - computed property is completely recomputed. - - Example - - ```javascript - Ember.Object.extend({ - // When `string` is changed, `computed` is completely recomputed. - string: 'a string', - - // When an item is added to `array`, `addedItem` is called. - array: [], - - // When an item is added to `anotherArray`, `computed` is completely - // recomputed. - anotherArray: [], - - computed: Ember.reduceComputed('string', 'array', 'anotherArray.[]', { - addedItem: addedItemCallback, - removedItem: removedItemCallback - }) - }); - ``` - - @method reduceComputed - @for Ember - @param {String} [dependentKeys*] - @param {Object} options - @return {Ember.ComputedProperty} -*/ -Ember.reduceComputed = function (options) { - var args; - - if (arguments.length > 1) { - args = a_slice.call(arguments, 0, -1); - options = a_slice.call(arguments, -1)[0]; - } - - if (typeof options !== "object") { - throw new Ember.Error("Reduce Computed Property declared without an options hash"); - } - - if (!('initialValue' in options)) { - throw new Ember.Error("Reduce Computed Property declared without an initial value"); - } - - var cp = new ReduceComputedProperty(options); - - if (args) { - cp.property.apply(cp, args); - } - - return cp; -}; - -})(); - - - -(function() { -var ReduceComputedProperty = Ember.ReduceComputedProperty, - a_slice = [].slice, - o_create = Ember.create, - forEach = Ember.EnumerableUtils.forEach; - -function ArrayComputedProperty() { - var cp = this; - - ReduceComputedProperty.apply(this, arguments); - - this.func = (function(reduceFunc) { - return function (propertyName) { - if (!cp._hasInstanceMeta(this, propertyName)) { - // When we recompute an array computed property, we need already - // retrieved arrays to be updated; we can't simply empty the cache and - // hope the array is re-retrieved. - forEach(cp._dependentKeys, function(dependentKey) { - Ember.addObserver(this, dependentKey, function() { - cp.recomputeOnce.call(this, propertyName); - }); - }, this); - } - - return reduceFunc.apply(this, arguments); - }; - })(this.func); - - return this; -} -Ember.ArrayComputedProperty = ArrayComputedProperty; -ArrayComputedProperty.prototype = o_create(ReduceComputedProperty.prototype); -ArrayComputedProperty.prototype.initialValue = function () { - return Ember.A(); -}; -ArrayComputedProperty.prototype.resetValue = function (array) { - array.clear(); - return array; -}; - -// This is a stopgap to keep the reference counts correct with lazy CPs. -ArrayComputedProperty.prototype.didChange = function (obj, keyName) { - return; -}; - -/** - Creates a computed property which operates on dependent arrays and - is updated with "one at a time" semantics.

You - can create a set to efficiently test for membership for an object. You can - also iterate through a set just like an array, even accessing objects by - index, however there is no guarantee as to their order. - - All Sets are observable via the Enumerable Observer API - which works - on any enumerable object including both Sets and Arrays. - - ## Creating a Set - - You can create a set like you would most objects using - `new Ember.Set()`. Most new sets you create will be empty, but you can - also initialize the set with some content by passing an array or other - enumerable of objects to the constructor. - - Finally, you can pass in an existing set and the set will be copied. You - can also create a copy of a set by calling `Ember.Set#copy()`. - - ```javascript - // creates a new empty set - var foundNames = new Ember.Set(); - - // creates a set with four names in it. - var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P - - // creates a copy of the names set. - var namesCopy = new Ember.Set(names); - - // same as above. - var anotherNamesCopy = names.copy(); - ``` - - ## Adding/Removing Objects - - You generally add or remove objects from a set using `add()` or - `remove()`. You can add any type of object including primitives such as - numbers, strings, and booleans. - - Unlike arrays, objects can only exist one time in a set. If you call `add()` - on a set with the same object multiple times, the object will only be added - once. Likewise, calling `remove()` with the same object multiple times will - remove the object the first time and have no effect on future calls until - you add the object to the set again. - - NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do - so will be ignored. - - In addition to add/remove you can also call `push()`/`pop()`. Push behaves - just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary - object, remove it and return it. This is a good way to use a set as a job - queue when you don't care which order the jobs are executed in. - - ## Testing for an Object - - To test for an object's presence in a set you simply call - `Ember.Set#contains()`. - - ## Observing changes - - When using `Ember.Set`, you can observe the `"[]"` property to be - alerted whenever the content changes. You can also add an enumerable - observer to the set to be notified of specific objects that are added and - removed from the set. See [Ember.Enumerable](/api/classes/Ember.Enumerable.html) - for more information on enumerables. - - This is often unhelpful. If you are filtering sets of objects, for instance, - it is very inefficient to re-filter all of the items each time the set - changes. It would be better if you could just adjust the filtered set based - on what was changed on the original set. The same issue applies to merging - sets, as well. - - ## Other Methods - - `Ember.Set` primary implements other mixin APIs. For a complete reference - on the methods you will use with `Ember.Set`, please consult these mixins. - The most useful ones will be `Ember.Enumerable` and - `Ember.MutableEnumerable` which implement most of the common iterator - methods you are used to on Array. - - Note that you can also use the `Ember.Copyable` and `Ember.Freezable` - APIs on `Ember.Set` as well. Once a set is frozen it can no longer be - modified. The benefit of this is that when you call `frozenCopy()` on it, - Ember will avoid making copies of the set.

- -/** - `Ember.ArrayController` provides a way for you to publish a collection of - objects so that you can easily bind to the collection from a Handlebars - `#each` helper, an `Ember.CollectionView`, or other controllers. - - The advantage of using an `ArrayController` is that you only have to set up - your view bindings once; to change what's displayed, simply swap out the - `content` property on the controller. - - For example, imagine you wanted to display a list of items fetched via an XHR - request. Create an `Ember.ArrayController` and set its `content` property: - - ```javascript - MyApp.listController = Ember.ArrayController.create(); - - $.get('people.json', function(data) { - MyApp.listController.set('content', data); - }); - ``` - - Then, create a view that binds to your new controller: - - ```handlebars - {{#each MyApp.listController}} - {{firstName}} {{lastName}} - {{/each}} - ``` - - Although you are binding to the controller, the behavior of this controller - is to pass through any methods or properties to the underlying array. This - capability comes from `Ember.ArrayProxy`, which this class inherits from. - - Sometimes you want to display computed properties within the body of an - `#each` helper that depend on the underlying items in `content`, but are not - present on those items. To do this, set `itemController` to the name of a - controller (probably an `ObjectController`) that will wrap each individual item. - - For example: - - ```handlebars - {{#each post in controller}} -
  • {{title}} ({{titleLength}} characters)
    • - {{/each}} - ``` - - ```javascript - App.PostsController = Ember.ArrayController.extend({ - itemController: 'post' - }); - - App.PostController = Ember.ObjectController.extend({ - // the `title` property will be proxied to the underlying post. - - titleLength: function() { - return this.get('title').length; - }.property('title') - }); - ``` - - In some cases it is helpful to return a different `itemController` depending - on the particular item. Subclasses can do this by overriding - `lookupItemController`. - - For example: - - ```javascript - App.MyArrayController = Ember.ArrayController.extend({ - lookupItemController: function( object ) { - if (object.get('isSpecial')) { - return "special"; // use App.SpecialController - } else { - return "regular"; // use App.RegularController - } - } - }); - ``` - - The itemController instances will have a `parentController` property set to - the `ArrayController` instance. - - @class ArrayController - @namespace Ember - @extends Ember.ArrayProxy - @uses Ember.SortableMixin - @uses Ember.ControllerMixin -*/ - -Ember.ArrayController = Ember.ArrayProxy.extend(Ember.ControllerMixin, - Ember.SortableMixin, { - - /** - The controller used to wrap items, if any. - - @property itemController - @type String - @default null - */ - itemController: null, - - /** - Return the name of the controller to wrap items, or `null` if items should - be returned directly.

The following view - class: - - ```javascript - ParagraphView = Ember.View.extend({ - tagName: 'em' - }); - ``` - - Would result in instances with the following HTML: - - ```html - - ``` - - ## HTML `class` Attribute - - The HTML `class` attribute of a view's tag can be set by providing a - `classNames` property that is set to an array of strings: - - ```javascript - MyView = Ember.View.extend({ - classNames: ['my-class', 'my-other-class'] - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    - ``` - - `class` attribute values can also be set by providing a `classNameBindings` - property set to an array of properties names for the view. The return value - of these properties will be added as part of the value for the view's `class` - attribute. These properties can be computed properties: - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['propertyA', 'propertyB'], - propertyA: 'from-a', - propertyB: function() { - if (someLogic) { return 'from-b'; } - }.property() - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    - ``` - - If the value of a class name binding returns a boolean the property name - itself will be used as the class name if the property is true. The class name - will not be added if the value is `false` or `undefined`. - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['hovered'], - hovered: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    - ``` - - When using boolean class name bindings you can supply a string value other - than the property name for use as the `class` HTML attribute by appending the - preferred value after a ":" character when defining the binding: - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['awesome:so-very-cool'], - awesome: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    - ``` - - Boolean value class name bindings whose property names are in a - camelCase-style format will be converted to a dasherized format: - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['isUrgent'], - isUrgent: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    - ``` - - Class name bindings can also refer to object values that are found by - traversing a path relative to the view itself: - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['messages.empty'] - messages: Ember.Object.create({ - empty: true - }) - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    - ``` - - If you want to add a class name for a property which evaluates to true and - and a different class name if it evaluates to false, you can pass a binding - like this: - - ```javascript - // Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false - Ember.View.extend({ - classNameBindings: ['isEnabled:enabled:disabled'] - isEnabled: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    - ``` - - When isEnabled is `false`, the resulting HTML reprensentation looks like - this: - - ```html -
    - ``` - - This syntax offers the convenience to add a class if a property is `false`: - - ```javascript - // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false - Ember.View.extend({ - classNameBindings: ['isEnabled::disabled'] - isEnabled: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    - ``` - - When the `isEnabled` property on the view is set to `false`, it will result - in view instances with an HTML representation of: - - ```html -
    - ``` - - Updates to the the value of a class name binding will result in automatic - update of the HTML `class` attribute in the view's rendered HTML - representation. If the value becomes `false` or `undefined` the class name - will be removed. - - Both `classNames` and `classNameBindings` are concatenated properties. See - [Ember.Object](/api/classes/Ember.Object.html) documentation for more - information about concatenated properties. - - ## HTML Attributes - - The HTML attribute section of a view's tag can be set by providing an - `attributeBindings` property set to an array of property names on the view. - The return value of these properties will be used as the value of the view's - HTML associated attribute: - - ```javascript - AnchorView = Ember.View.extend({ - tagName: 'a', - attributeBindings: ['href'], - href: 'http://google.com' - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - - ``` - - If the return value of an `attributeBindings` monitored property is a boolean - the property will follow HTML's pattern of repeating the attribute's name as - its value: - - ```javascript - MyTextInput = Ember.View.extend({ - tagName: 'input', - attributeBindings: ['disabled'], - disabled: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - - ``` - - `attributeBindings` can refer to computed properties: - - ```javascript - MyTextInput = Ember.View.extend({ - tagName: 'input', - attributeBindings: ['disabled'], - disabled: function() { - if (someLogic) { - return true; - } else { - return false; - } - }.property() - }); - ``` - - Updates to the the property of an attribute binding will result in automatic - update of the HTML attribute in the view's rendered HTML representation. - - `attributeBindings` is a concatenated property. See [Ember.Object](/api/classes/Ember.Object.html) - documentation for more information about concatenated properties. - - ## Templates - - The HTML contents of a view's rendered representation are determined by its - template. Templates can be any function that accepts an optional context - parameter and returns a string of HTML that will be inserted within the - view's tag. Most typically in Ember this function will be a compiled - `Ember.Handlebars` template. - - ```javascript - AView = Ember.View.extend({ - template: Ember.Handlebars.compile('I am the template') - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    I am the template
    - ``` - - Within an Ember application is more common to define a Handlebars templates as - part of a page: - - ```html - - ``` - - And associate it by name using a view's `templateName` property: - - ```javascript - AView = Ember.View.extend({ - templateName: 'some-template' - }); - ``` - - If you have nested resources, your Handlebars template will look like this: - - ```html - - ``` - - And `templateName` property: - - ```javascript - AView = Ember.View.extend({ - templateName: 'posts/new' - }); - ``` - - Using a value for `templateName` that does not have a Handlebars template - with a matching `data-template-name` attribute will throw an error. - - For views classes that may have a template later defined (e.g. as the block - portion of a `{{view}}` Handlebars helper call in another template or in - a subclass), you can provide a `defaultTemplate` property set to compiled - template function. If a template is not later provided for the view instance - the `defaultTemplate` value will be used: - - ```javascript - AView = Ember.View.extend({ - defaultTemplate: Ember.Handlebars.compile('I was the default'), - template: null, - templateName: null - }); - ``` - - Will result in instances with an HTML representation of: - - ```html -
    I was the default
    - ``` - - If a `template` or `templateName` is provided it will take precedence over - `defaultTemplate`: - - ```javascript - AView = Ember.View.extend({ - defaultTemplate: Ember.Handlebars.compile('I was the default') - }); - - aView = AView.create({ - template: Ember.Handlebars.compile('I was the template, not default') - }); - ``` - - Will result in the following HTML representation when rendered: - - ```html -
    I was the template, not default
    - ``` - - ## View Context - - The default context of the compiled template is the view's controller: - - ```javascript - AView = Ember.View.extend({ - template: Ember.Handlebars.compile('Hello {{excitedGreeting}}') - }); - - aController = Ember.Object.create({ - firstName: 'Barry', - excitedGreeting: function() { - return this.get("content.firstName") + "!!!" - }.property() - }); - - aView = AView.create({ - controller: aController, - }); - ``` - - Will result in an HTML representation of: - - ```html -
    Hello Barry!!!
    - ``` - - A context can also be explicitly supplied through the view's `context` - property. If the view has neither `context` nor `controller` properties, the - `parentView`'s context will be used. - - ## Layouts - - Views can have a secondary template that wraps their main template. Like - primary templates, layouts can be any function that accepts an optional - context parameter and returns a string of HTML that will be inserted inside - view's tag. Views whose HTML element is self closing (e.g. ``) - cannot have a layout and this property will be ignored. - - Most typically in Ember a layout will be a compiled `Ember.Handlebars` - template. - - A view's layout can be set directly with the `layout` property or reference - an existing Handlebars template by name with the `layoutName` property. - - A template used as a layout must contain a single use of the Handlebars - `{{yield}}` helper. The HTML contents of a view's rendered `template` will be - inserted at this location: - - ```javascript - AViewWithLayout = Ember.View.extend({ - layout: Ember.Handlebars.compile("
    {{yield}}
    ") - template: Ember.Handlebars.compile("I got wrapped"), - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
    -
    - I got wrapped -
    -
    - ``` - - See [Ember.Handlebars.helpers.yield](/api/classes/Ember.Handlebars.helpers.html#method_yield) - for more information. - - ## Responding to Browser Events - - Views can respond to user-initiated events in one of three ways: method - implementation, through an event manager, and through `{{action}}` helper use - in their template or layout. - - ### Method Implementation - - Views can respond to user-initiated events by implementing a method that - matches the event name. A `jQuery.Event` object will be passed as the - argument to this method. - - ```javascript - AView = Ember.View.extend({ - click: function(event) { - // will be called when when an instance's - // rendered element is clicked - } - }); - ``` - - ### Event Managers - - Views can define an object as their `eventManager` property. This object can - then implement methods that match the desired event names. Matching events - that occur on the view's rendered HTML or the rendered HTML of any of its DOM - descendants will trigger this method. A `jQuery.Event` object will be passed - as the first argument to the method and an `Ember.View` object as the - second. The `Ember.View` will be the view whose rendered HTML was interacted - with. This may be the view with the `eventManager` property or one of its - descendent views. - - ```javascript - AView = Ember.View.extend({ - eventManager: Ember.Object.create({ - doubleClick: function(event, view) { - // will be called when when an instance's - // rendered element or any rendering - // of this views's descendent - // elements is clicked - } - }) - }); - ``` - - An event defined for an event manager takes precedence over events of the - same name handled through methods on the view. - - ```javascript - AView = Ember.View.extend({ - mouseEnter: function(event) { - // will never trigger. - }, - eventManager: Ember.Object.create({ - mouseEnter: function(event, view) { - // takes precedence over AView#mouseEnter - } - }) - }); - ``` - - Similarly a view's event manager will take precedence for events of any views - rendered as a descendent. A method name that matches an event name will not - be called if the view instance was rendered inside the HTML representation of - a view that has an `eventManager` property defined that handles events of the - name. Events not handled by the event manager will still trigger method calls - on the descendent. - - ```javascript - OuterView = Ember.View.extend({ - template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"), - eventManager: Ember.Object.create({ - mouseEnter: function(event, view) { - // view might be instance of either - // OuterView or InnerView depending on - // where on the page the user interaction occured - } - }) - }); - - InnerView = Ember.View.extend({ - click: function(event) { - // will be called if rendered inside - // an OuterView because OuterView's - // eventManager doesn't handle click events - }, - mouseEnter: function(event) { - // will never be called if rendered inside - // an OuterView. - } - }); - ``` - - ### Handlebars `{{action}}` Helper - - See [Handlebars.helpers.action](/api/classes/Ember.Handlebars.helpers.html#method_action). - - ### Event Names - - All of the event handling approaches described above respond to the same set - of events. The names of the built-in events are listed below. (The hash of - built-in events exists in `Ember.EventDispatcher`.) Additional, custom events - can be registered by using `Ember.Application.customEvents`. - - Touch events: - - * `touchStart` - * `touchMove` - * `touchEnd` - * `touchCancel` - - Keyboard events - - * `keyDown` - * `keyUp` - * `keyPress` - - Mouse events - - * `mouseDown` - * `mouseUp` - * `contextMenu` - * `click` - * `doubleClick` - * `mouseMove` - * `focusIn` - * `focusOut` - * `mouseEnter` - * `mouseLeave` - - Form events: - - * `submit` - * `change` - * `focusIn` - * `focusOut` - * `input` - - HTML5 drag and drop events: - - * `dragStart` - * `drag` - * `dragEnter` - * `dragLeave` - * `drop` - * `dragEnd` - - ## Handlebars `{{view}}` Helper - - Other `Ember.View` instances can be included as part of a view's template by - using the `{{view}}` Handlebars helper.

    -
    - ``` - - `{{with}}` can be our best friend in these cases, - instead of writing `user.role.*` over and over, we use `{{#with user.role}}`. - Now the context within the `{{#with}} .. {{/with}}` block is `user.role` so you can do the following: - - ```handlebars -
    {{user.name}}
    - -
    - {{#with user.role}} -
    {{label}}
    - {{id}} - -

    {{description}}

    - {{/with}} -
    - ``` - - ### `as` operator - - This operator aliases the scope to a new name. It's helpful for semantic clarity and to retain - default scope or to reference from another `{{with}}` block. - - ```handlebars - // posts might not be - {{#with user.posts as blogPosts}} -
    - There are {{blogPosts.length}} blog posts written by {{user.name}}. -
    - - {{#each post in blogPosts}} -
  • {{post.title}}
    • - {{/each}} - {{/with}} - ``` - - Without the `as` operator, it would be impossible to reference `user.name` in the example above. - - NOTE: The alias should not reuse a name from the bound property path. - For example: `{{#with foo.bar as foo}}` is not supported because it attempts to alias using - the first part of the property path, `foo`. Instead, use `{{#with foo.bar as baz}}`. - - ### `controller` option - - Adding `controller='something'` instructs the `{{with}}` helper to create and use an instance of - the specified controller with the new context as its content. - - This is very similar to using an `itemController` option with the `{{each}}` helper. - - ```handlebars - {{#with users.posts controller='userBlogPosts'}} - {{!- The current context is wrapped in our controller instance }} - {{/with}} - ``` - - In the above example, the template provided to the `{{with}}` block is now wrapped in the - `userBlogPost` controller, which provides a very elegant way to decorate the context with custom - functions/properties. - - @method with - @for Ember.Handlebars.helpers - @param {Function} context - @param {Hash} options - @return {String} HTML string -*/ -EmberHandlebars.registerHelper('with', function withHelper(context, options) { - if (arguments.length === 4) { - var keywordName, path, rootPath, normalized, contextPath; - - Ember.assert("If you pass more than one argument to the with helper, it must be in the form #with foo as bar", arguments[1] === "as"); - options = arguments[3]; - keywordName = arguments[2]; - path = arguments[0]; - - Ember.assert("You must pass a block to the with helper", options.fn && options.fn !== Handlebars.VM.noop); - - var localizedOptions = o_create(options); - localizedOptions.data = o_create(options.data); - localizedOptions.data.keywords = o_create(options.data.keywords || {}); - - if (Ember.isGlobalPath(path)) { - contextPath = path; - } else { - normalized = normalizePath(this, path, options.data); - path = normalized.path; - rootPath = normalized.root; - - // This is a workaround for the fact that you cannot bind separate objects - // together.

The use of `src` - in the following `bind-attr` example will be ignored and the hard coded value - of `src="/failwhale.gif"` will take precedence: - - ```handlebars - imageTitle - ``` - - ### `bind-attr` and the `class` attribute - - `bind-attr` supports a special syntax for handling a number of cases unique - to the `class` DOM element attribute. The `class` attribute combines - multiple discrete values into a single attribute as a space-delimited - list of strings. Each string can be: - - * a string return value of an object's property. - * a boolean return value of an object's property - * a hard-coded value - - A string return value works identically to other uses of `bind-attr`. The - return value of the property will become the value of the attribute. For - example, the following view and template: - - ```javascript - AView = Ember.View.extend({ - someProperty: function() { - return "aValue"; - }.property() - }) - ``` - - ```handlebars - - ``` - - A boolean return value will insert a specified class name if the property - returns `true` and remove the class name if the property returns `false`. - - A class name is provided via the syntax - `somePropertyName:class-name-if-true`. - - ```javascript - AView = Ember.View.extend({ - someBool: true - }) - ``` - - ```handlebars - - ``` - - Result in the following rendered output: - - ```html - - ``` - - An additional section of the binding can be provided if you want to - replace the existing class instead of removing it when the boolean - value changes: - - ```handlebars - - ``` - - A hard-coded value can be used by prepending `:` to the desired - class name: `:class-name-to-always-apply`. - - ```handlebars - - ``` - - Results in the following rendered output: - - ```html - - ``` - - All three strategies - string return value, boolean return value, and - hard-coded value – can be combined in a single declaration: - - ```handlebars - - ``` - - @method bind-attr - @for Ember.Handlebars.helpers - @param {Hash} options - @return {String} HTML string -*/ -EmberHandlebars.registerHelper('bind-attr', function bindAttrHelper(options) { - - var attrs = options.hash; - - Ember.assert("You must specify at least one hash argument to bind-attr", !!Ember.keys(attrs).length); - - var view = options.data.view; - var ret = []; - var ctx = this; - - // Generate a unique id for this element.

    - A span: - - Hello. - -
    - - ``` - - ### `parentView` setting - - The `parentView` property of the new `Ember.View` instance created through - `{{view}}` will be set to the `Ember.View` instance of the template where - `{{view}}` was called. - - ```javascript - aView = Ember.View.create({ - template: Ember.Handlebars.compile("{{#view}} my parent: {{parentView.elementId}} {{/view}}") - }); - - aView.appendTo('body'); - ``` - - Will result in HTML structure: - - ```html -
    -
    - my parent: ember1 -
    -
    - ``` - - ### Setting CSS id and class attributes - - The HTML `id` attribute can be set on the `{{view}}`'s resulting element with - the `id` option. This option will _not_ be passed to `Ember.View.create`. - - ```handlebars - {{#view tagName="span" id="a-custom-id"}} - hello. - {{/view}} - ``` - - Results in the following HTML structure: - - ```html -
    - - hello. - -
    - ``` - - The HTML `class` attribute can be set on the `{{view}}`'s resulting element - with the `class` or `classNameBindings` options. The `class` option will - directly set the CSS `class` attribute and will not be passed to - `Ember.View.create`. `classNameBindings` will be passed to `create` and use - `Ember.View`'s class name binding functionality: - - ```handlebars - {{#view tagName="span" class="a-custom-class"}} - hello. - {{/view}} - ``` - - Results in the following HTML structure: - - ```html -
    - - hello. - -
    - ``` - - ### Supplying a different view class - - `{{view}}` can take an optional first argument before its supplied options to - specify a path to a custom view class. - - ```handlebars - {{#view "MyApp.CustomView"}} - hello. - {{/view}} - ``` - - The first argument can also be a relative path accessible from the current - context. - - ```javascript - MyApp = Ember.Application.create({}); - MyApp.OuterView = Ember.View.extend({ - innerViewClass: Ember.View.extend({ - classNames: ['a-custom-view-class-as-property'] - }), - template: Ember.Handlebars.compile('{{#view "view.innerViewClass"}} hi {{/view}}') - }); - - MyApp.OuterView.create().appendTo('body'); - ``` - - Will result in the following HTML: - - ```html -
    -
    - hi -
    -
    - ``` - - ### Blockless use - - If you supply a custom `Ember.View` subclass that specifies its own template - or provide a `templateName` option to `{{view}}` it can be used without - supplying a block. Attempts to use both a `templateName` option and supply a - block will throw an error. - - ```handlebars - {{view "MyApp.ViewWithATemplateDefined"}} - ``` - - ### `viewName` property - - You can supply a `viewName` option to `{{view}}`. The `Ember.View` instance - will be referenced as a property of its parent view by this name. - - ```javascript - aView = Ember.View.create({ - template: Ember.Handlebars.compile('{{#view viewName="aChildByName"}} hi {{/view}}') - }); - - aView.appendTo('body'); - aView.get('aChildByName') // the instance of Ember.View created by {{view}} helper - ``` - - @method view - @for Ember.Handlebars.helpers - @param {String} path - @param {Hash} options - @return {String} HTML string -*/ -EmberHandlebars.registerHelper('view', function viewHelper(path, options) { - Ember.assert("The view helper only takes a single argument", arguments.length <= 2); - - // If no path is provided, treat path param as options. - if (path && path.data && path.data.isRenderData) { - options = path; - path = "Ember.View"; - } - - return EmberHandlebars.ViewHelper.helper(this, path, options); -}); - - -})(); - - - -(function() { -// TODO: Don't require all of this module -/** -@module ember -@submodule ember-handlebars -*/ - -var get = Ember.get, handlebarsGet = Ember.Handlebars.get, fmt = Ember.String.fmt; - -/** - `{{collection}}` is a `Ember.Handlebars` helper for adding instances of - `Ember.CollectionView` to a template.

    -
    Hi Mary
    -
    Hi Sara
    -
    - ``` - - ### Blockless use in a collection - - If you provide an `itemViewClass` option that has its own `template` you can - omit the block. - - The following template: - - ```handlebars - {{collection contentBinding="App.items" itemViewClass="App.AnItemView"}} - ``` - - And application code - - ```javascript - App = Ember.Application.create(); - App.items = [ - Ember.Object.create({name: 'Dave'}), - Ember.Object.create({name: 'Mary'}), - Ember.Object.create({name: 'Sara'}) - ]; - - App.AnItemView = Ember.View.extend({ - template: Ember.Handlebars.compile("Greetings {{view.content.name}}") - }); - ``` - - Will result in the HTML structure below - - ```html -
    -
    Greetings Dave
    -
    Greetings Mary
    -
    Greetings Sara
    -
    - ``` - - ### Specifying a CollectionView subclass - - By default the `{{collection}}` helper will create an instance of - `Ember.CollectionView`. You can supply a `Ember.CollectionView` subclass to - the helper by passing it as the first argument: - - ```handlebars - {{#collection App.MyCustomCollectionClass contentBinding="App.items"}} - Hi {{view.content.name}} - {{/collection}} - ``` - - ### Forwarded `item.*`-named Options - - As with the `{{view}}`, helper options passed to the `{{collection}}` will be - set on the resulting `Ember.CollectionView` as properties. Additionally, - options prefixed with `item` will be applied to the views rendered for each - item (note the camelcasing): - - ```handlebars - {{#collection contentBinding="App.items" - itemTagName="p" - itemClassNames="greeting"}} - Howdy {{view.content.name}} - {{/collection}} - ``` - - Will result in the following HTML structure: - - ```html -

    -
    - ``` - - If an `itemViewClass` is defined on the helper, and therefore the helper is not - being used as a block, an `emptyViewClass` can also be provided optionally. - The `emptyViewClass` will match the behavior of the `{{else}}` condition - described above. That is, the `emptyViewClass` will render if the collection - is empty. - - ### Representing each item with a Controller. - By default the controller lookup within an `{{#each}}` block will be - the controller of the template where the `{{#each}}` was used. If each - item needs to be presented by a custom controller you can provide a - `itemController` option which references a controller by lookup name. - Each item in the loop will be wrapped in an instance of this controller - and the item itself will be set to the `content` property of that controller. - - This is useful in cases where properties of model objects need transformation - or synthesis for display: - - ```javascript - App.DeveloperController = Ember.ObjectController.extend({ - isAvailableForHire: function() { - return !this.get('content.isEmployed') && this.get('content.isSeekingWork'); - }.property('isEmployed', 'isSeekingWork') - }) - ``` - - ```handlebars - {{#each person in developers itemController="developer"}} - {{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}} - {{/each}} - ``` - - Each itemController will receive a reference to the current controller as - a `parentController` property. - - ### (Experimental) Grouped Each - - When used in conjunction with the experimental [group helper](https://github.com/emberjs/group-helper), - you can inform Handlebars to re-render an entire group of items instead of - re-rendering them one at a time (in the event that they are changed en masse - or an item is added/removed). - - ```handlebars - {{#group}} - {{#each people}} - {{firstName}} {{lastName}} - {{/each}} - {{/group}} - ``` - - This can be faster than the normal way that Handlebars re-renders items - in some cases. - - If for some reason you have a group with more than one `#each`, you can make - one of the collections be updated in normal (non-grouped) fashion by setting - the option `groupedRows=true` (counter-intuitive, I know). - - For example, - - ```handlebars - {{dealershipName}} - - {{#group}} - {{#each dealers}} - {{firstName}} {{lastName}} - {{/each}} - - {{#each car in cars groupedRows=true}} - {{car.make}} {{car.model}} {{car.color}} - {{/each}} - {{/group}} - ``` - Any change to `dealershipName` or the `dealers` collection will cause the - entire group to be re-rendered.

For example, - if you wanted to add a css class to all checkboxes in your application: - - - ```javascript - Ember.Checkbox.reopen({ - classNames: ['my-app-checkbox'] - }); - ``` - - - @method input - @for Ember.Handlebars.helpers - @param {Hash} options -*/ -Ember.Handlebars.registerHelper('input', function(options) { - Ember.assert('You can only pass attributes to the `input` helper, not arguments', arguments.length < 2); - - var hash = options.hash, - types = options.hashTypes, - inputType = hash.type, - onEvent = hash.on; - - delete hash.type; - delete hash.on; - - if (inputType === 'checkbox') { - Ember.assert("{{input type='checkbox'}} does not support setting `value=someBooleanValue`; you must use `checked=someBooleanValue` instead.", options.hashTypes.value !== 'ID'); - return Ember.Handlebars.helpers.view.call(this, Ember.Checkbox, options); - } else { - if (inputType) { hash.type = inputType; } - hash.onEvent = onEvent || 'enter'; - return Ember.Handlebars.helpers.view.call(this, Ember.TextField, options); - } -}); - -/** - `{{textarea}}` inserts a new instance of ` - ``` - - Bound: - - In the following example, the `writtenWords` property on `App.ApplicationController` - will be updated live as the user types 'Lots of text that IS bound' into - the text area of their browser's window. - - ```javascript - App.ApplicationController = Ember.Controller.extend({ - writtenWords: "Lots of text that IS bound" - }); - ``` - - ```handlebars - {{textarea value=writtenWords}} - ``` - - Would result in the following HTML: - - ```html - - ``` - - If you wanted a one way binding between the text area and a div tag - somewhere else on your screen, you could use `Ember.computed.oneWay`: - - ```javascript - App.ApplicationController = Ember.Controller.extend({ - writtenWords: "Lots of text that IS bound", - outputWrittenWords: Ember.computed.oneWay("writtenWords") - }); - ``` - - ```handlebars - {{textarea value=writtenWords}} - -

    - Lots of text that IS bound -
    - ``` - - Finally, this example really shows the power and ease of Ember when two - properties are bound to eachother via `Ember.computed.alias`. Type into - either text area box and they'll both stay in sync. Note that - `Ember.computed.alias` costs more in terms of performance, so only use it when - your really binding in both directions: - - ```javascript - App.ApplicationController = Ember.Controller.extend({ - writtenWords: "Lots of text that IS bound", - twoWayWrittenWords: Ember.computed.alias("writtenWords") - }); - ``` - - ```handlebars - {{textarea value=writtenWords}} - {{textarea value=twoWayWrittenWords}} - ``` - - ```html - - - <-- both updated in real time --> - - - ``` - - ## Extension - - Internally, `{{textarea}}` creates an instance of `Ember.TextArea`, passing - arguments from the helper to `Ember.TextArea`'s `create` method. You can - extend the capabilities of text areas in your application by reopening this - class. For example, if you are deploying to browsers where the `required` - attribute is used, you can globally add support for the `required` attribute - on all `{{textarea}}`s' in your app by reopening `Ember.TextArea` or - `Ember.TextSupport` and adding it to the `attributeBindings` concatenated - property: - - ```javascript - Ember.TextArea.reopen({ - attributeBindings: ['required'] - }); - ``` - - Keep in mind when writing `Ember.TextArea` subclasses that `Ember.TextArea` - itself extends `Ember.Component`, meaning that it does NOT inherit - the `controller` of the parent view. - - See more about [Ember components](api/classes/Ember.Component.html) - - @method textarea - @for Ember.Handlebars.helpers - @param {Hash} options -*/ -Ember.Handlebars.registerHelper('textarea', function(options) { - Ember.assert('You can only pass attributes to the `textarea` helper, not arguments', arguments.length < 2); - - var hash = options.hash, - types = options.hashTypes; - - return Ember.Handlebars.helpers.view.call(this, Ember.TextArea, options); -}); - -})(); - - - -(function() { -Ember.ComponentLookup = Ember.Object.extend({ - lookupFactory: function(name, container) { - - container = container || this.container; - - var fullName = 'component:' + name, - templateFullName = 'template:components/' + name, - templateRegistered = container && container.has(templateFullName); - - if (templateRegistered) { - container.injection(fullName, 'layout', templateFullName); - } - - var Component = container.lookupFactory(fullName); - - // Only treat as a component if either the component - // or a template has been registered. - if (templateRegistered || Component) { - if (!Component) { - container.register(fullName, Ember.Component); - Component = container.lookupFactory(fullName); - } - return Component; - } - } -}); - -})(); - - - -(function() { -/*globals Handlebars */ -/** -@module ember -@submodule ember-handlebars -*/ - -/** - Find templates stored in the head tag as script tags and make them available - to `Ember.CoreView` in the global `Ember.TEMPLATES` object.

This can - be overridden for a single use of `{{link-to}}` by supplying - a `tagName` option: - - ```handlebars - {{#link-to 'photoGallery' tagName="li"}} - Great Hamster Photos - {{/link-to}} - ``` - - ```html -
  • - Great Hamster Photos -
    • - ``` - - To override this option for your entire application, see - "Overriding Application-wide Defaults". - - ### Disabling the `link-to` helper - By default `{{link-to}}` is enabled. - any passed value to `disabled` helper property will disable the `link-to` helper. - - static use: the `disabled` option: - - ```handlebars - {{#link-to 'photoGallery' disabled=true}} - Great Hamster Photos - {{/link-to}} - ``` - - dynamic use: the `disabledWhen` option: - - ```handlebars - {{#link-to 'photoGallery' disabledWhen=controller.someProperty}} - Great Hamster Photos - {{/link-to}} - ``` - - any passed value to `disabled` will disable it except `undefined`. - to ensure that only `true` disable the `link-to` helper you can - override the global behaviour of `Ember.LinkView`. - - ```javascript - Ember.LinkView.reopen({ - disabled: Ember.computed(function(key, value) { - if (value !== undefined) { - this.set('_isDisabled', value === true); - } - return value === true ? get(this, 'disabledClass') : false; - }) - }); - ``` - - see "Overriding Application-wide Defaults" for more. - - ### Handling `href` - `{{link-to}}` will use your application's Router to - fill the element's `href` property with a url that - matches the path to the supplied `routeName` for your - routers's configured `Location` scheme, which defaults - to Ember.HashLocation. - - ### Handling current route - `{{link-to}}` will apply a CSS class name of 'active' - when the application's current route matches - the supplied routeName. For example, if the application's - current route is 'photoGallery.recent' the following - use of `{{link-to}}`: - - ```handlebars - {{#link-to 'photoGallery.recent'}} - Great Hamster Photos from the last week - {{/link-to}} - ``` - - will result in - - ```html -     - Great Hamster Photos - - ``` - - The CSS class name used for active classes can be customized - for a single use of `{{link-to}}` by passing an `activeClass` - option: - - ```handlebars - {{#link-to 'photoGallery.recent' activeClass="current-url"}} - Great Hamster Photos from the last week - {{/link-to}} - ``` - - ```html - - Great Hamster Photos - - ``` - - To override this option for your entire application, see - "Overriding Application-wide Defaults". - - ### Supplying a model - An optional model argument can be used for routes whose - paths contain dynamic segments. This argument will become - the model context of the linked route: - - ```javascript - App.Router.map(function() { - this.resource("photoGallery", {path: "hamster-photos/:photo_id"}); - }); - ``` - - ```handlebars - {{#link-to 'photoGallery' aPhoto}} - {{aPhoto.title}} - {{/link-to}} - ``` - - ```html - - Tomster - - ``` - - ### Supplying multiple models - For deep-linking to route paths that contain multiple - dynamic segments, multiple model arguments can be used. - As the router transitions through the route path, each - supplied model argument will become the context for the - route with the dynamic segments: - - ```javascript - App.Router.map(function() { - this.resource("photoGallery", {path: "hamster-photos/:photo_id"}, function() { - this.route("comment", {path: "comments/:comment_id"}); - }); - }); - ``` - This argument will become the model context of the linked route: - - ```handlebars - {{#link-to 'photoGallery.comment' aPhoto comment}} - {{comment.body}} - {{/link-to}} - ``` - - ```html - - A+++ would snuggle again. - - ``` - - ### Supplying an explicit dynamic segment value - If you don't have a model object available to pass to `{{link-to}}`, - an optional string or integer argument can be passed for routes whose - paths contain dynamic segments. This argument will become the value - of the dynamic segment: - - ```javascript - App.Router.map(function() { - this.resource("photoGallery", {path: "hamster-photos/:photo_id"}); - }); - ``` - - ```handlebars - {{#link-to 'photoGallery' aPhotoId}} - {{aPhoto.title}} - {{/link-to}} - ``` - - ```html - - Tomster - - ``` - - When transitioning into the linked route, the `model` hook will - be triggered with parameters including this passed identifier. - - ### Allowing Default Action - - By default the `{{link-to}}` helper prevents the default browser action - by calling `preventDefault()` as this sort of action bubbling is normally - handled internally and we do not want to take the browser to a new URL (for - example). - - If you need to override this behavior specify `preventDefault=false` in - your template: - - ```handlebars - {{#link-to 'photoGallery' aPhotoId preventDefault=false}} - {{aPhotoId.title}} - {{/link-to}} - ``` - - ### Overriding attributes - You can override any given property of the Ember.LinkView - that is generated by the `{{link-to}}` helper by passing - key/value pairs, like so: - - ```handlebars - {{#link-to aPhoto tagName='li' title='Following this link will change your life' classNames='pic sweet'}} - Uh-mazing! - {{/link-to}} - ``` - - See [Ember.LinkView](/api/classes/Ember.LinkView.html) for a - complete list of overrideable properties. Be sure to also - check out inherited properties of `LinkView`. - - ### Overriding Application-wide Defaults - ``{{link-to}}`` creates an instance of Ember.LinkView - for rendering.

You do not need to do so in your event - handlers. If you need to allow event propagation (to handle file inputs for - example) you can supply the `preventDefault=false` option to the `{{action}}` helper: - - ```handlebars -
    - - -
    - ``` - - To disable bubbling, pass `bubbles=false` to the helper: - - ```handlebars - - ``` - - If you need the default handler to trigger you should either register your - own event handler, or use event methods on your view class. See [Ember.View](/api/classes/Ember.View.html) - 'Responding to Browser Events' for more information. - - ### Specifying DOM event type - - By default the `{{action}}` helper registers for DOM `click` events. You can - supply an `on` option to the helper to specify a different DOM event name: - - ```handlebars -
    - click me -
    - ``` - - See `Ember.View` 'Responding to Browser Events' for a list of - acceptable DOM event names. - - NOTE: Because `{{action}}` depends on Ember's event dispatch system it will - only function if an `Ember.EventDispatcher` instance is available. An - `Ember.EventDispatcher` instance will be created when a new `Ember.Application` - is created. Having an instance of `Ember.Application` will satisfy this - requirement. - - ### Specifying whitelisted modifier keys - - By default the `{{action}}` helper will ignore click event with pressed modifier - keys. You can supply an `allowedKeys` option to specify which keys should not be ignored. - - ```handlebars -
    - click me -
    - ``` - - This way the `{{action}}` will fire when clicking with the alt key pressed down. - - Alternatively, supply "any" to the `allowedKeys` option to accept any combination of modifier keys. - - ```handlebars -
    - click me with any key pressed -
    - ``` - - ### Specifying a Target - - There are several possible target objects for `{{action}}` helpers: - - In a typical Ember application, where views are managed through use of the - `{{outlet}}` helper, actions will bubble to the current controller, then - to the current route, and then up the route hierarchy. - - Alternatively, a `target` option can be provided to the helper to change - which object will receive the method call. This option must be a path - to an object, accessible in the current context: - - ```handlebars - {{! the application template }} -
    - click me -
    - ``` - - ```javascript - App.ApplicationView = Ember.View.extend({ - actions: { - anActionName: function(){} - } - }); - - ``` - - ### Additional Parameters - - You may specify additional parameters to the `{{action}}` helper.

It helps to instantiate, initialize and coordinate the many - objects that make up your app. - - Each Ember app has one and only one `Ember.Application` object. In fact, the - very first thing you should do in your application is create the instance: - - ```javascript - window.App = Ember.Application.create(); - ``` - - Typically, the application object is the only global variable. All other - classes in your app should be properties on the `Ember.Application` instance, - which highlights its first role: a global namespace. - - For example, if you define a view class, it might look like this: - - ```javascript - App.MyView = Ember.View.extend(); - ``` - - By default, calling `Ember.Application.create()` will automatically initialize - your application by calling the `Ember.Application.initialize()` method. If - you need to delay initialization, you can call your app's `deferReadiness()` - method. When you are ready for your app to be initialized, call its - `advanceReadiness()` method. - - You can define a `ready` method on the `Ember.Application` instance, which - will be run by Ember when the application is initialized. - - Because `Ember.Application` inherits from `Ember.Namespace`, any classes - you create will have useful string representations when calling `toString()`. - See the `Ember.Namespace` documentation for more information. - - While you can think of your `Ember.Application` as a container that holds the - other classes in your application, there are several other responsibilities - going on under-the-hood that you may want to understand. - - ### Event Delegation - - Ember uses a technique called _event delegation_. This allows the framework - to set up a global, shared event listener instead of requiring each view to - do it manually. For example, instead of each view registering its own - `mousedown` listener on its associated element, Ember sets up a `mousedown` - listener on the `body`. - - If a `mousedown` event occurs, Ember will look at the target of the event and - start walking up the DOM node tree, finding corresponding views and invoking - their `mouseDown` method as it goes. - - `Ember.Application` has a number of default events that it listens for, as - well as a mapping from lowercase events to camel-cased view method names. For - example, the `keypress` event causes the `keyPress` method on the view to be - called, the `dblclick` event causes `doubleClick` to be called, and so on. - - If there is a bubbling browser event that Ember does not listen for by - default, you can specify custom events and their corresponding view method - names by setting the application's `customEvents` property: - - ```javascript - App = Ember.Application.create({ - customEvents: { - // add support for the paste event - paste: "paste" - } - }); - ``` - - By default, the application sets up these event listeners on the document - body. However, in cases where you are embedding an Ember application inside - an existing page, you may want it to set up the listeners on an element - inside the body. - - For example, if only events inside a DOM element with the ID of `ember-app` - should be delegated, set your application's `rootElement` property: - - ```javascript - window.App = Ember.Application.create({ - rootElement: '#ember-app' - }); - ``` - - The `rootElement` can be either a DOM element or a jQuery-compatible selector - string. Note that *views appended to the DOM outside the root element will - not receive events.* If you specify a custom root element, make sure you only - append views inside it! - - To learn more about the advantages of event delegation and the Ember view - layer, and a list of the event listeners that are setup by default, visit the - [Ember View Layer guide](http://emberjs.com/guides/understanding-ember/the-view-layer/#toc_event-delegation). - - ### Initializers - - Libraries on top of Ember can add initializers, like so: - - ```javascript - Ember.Application.initializer({ - name: 'api-adapter', - - initialize: function(container, application) { - application.register('api-adapter:main', ApiAdapter); - } - }); - ``` - - Initializers provide an opportunity to access the container, which - organizes the different components of an Ember application. Additionally - they provide a chance to access the instantiated application. Beyond - being used for libraries, initializers are also a great way to organize - dependency injection or setup in your own application. - - ### Routing - - In addition to creating your application's router, `Ember.Application` is - also responsible for telling the router when to start routing. Transitions - between routes can be logged with the `LOG_TRANSITIONS` flag, and more - detailed intra-transition logging can be logged with - the `LOG_TRANSITIONS_INTERNAL` flag: - - ```javascript - window.App = Ember.Application.create({ - LOG_TRANSITIONS: true, // basic logging of successful transitions - LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps - }); - ``` - - By default, the router will begin trying to translate the current URL into - application state once the browser emits the `DOMContentReady` event. If you - need to defer routing, you can call the application's `deferReadiness()` - method. Once routing can begin, call the `advanceReadiness()` method. - - If there is any setup required before routing begins, you can implement a - `ready()` method on your app that will be invoked immediately before routing - begins. - ``` - - @class Application - @namespace Ember - @extends Ember.Namespace -*/ - -var Application = Ember.Application = Ember.Namespace.extend(Ember.DeferredMixin, { - - /** - The root DOM element of the Application.

Instantiating a class - directly (via `create` or `new`) bypasses the dependency injection - system. - - Ember-Data instantiates its models in a unique manner, and consequently - injections onto models (or all models) will not work as expected. Injections - on models can be enabled by setting `Ember.MODEL_FACTORY_INJECTIONS` - to `true`. - - @method inject - @param factoryNameOrType {String} - @param property {String} - @param injectionName {String} - **/ - inject: function() { - var container = this.__container__; - container.injection.apply(container, arguments); - }, - - /** - Calling initialize manually is not supported. - - Please see Ember.Application#advanceReadiness and - Ember.Application#deferReadiness. - - @private - @deprecated - @method initialize - **/ - initialize: function() { - Ember.deprecate('Calling initialize manually is not supported.
