`_addAttrs`

(

cfgs
values
lazy

)

private

Inherited from AttributeCore: yui3/src/attribute/js/AttributeCore.js:877

Implementation behind the public addAttrs method. This method is invoked directly by get if it encounters a scenario in which an attribute's valueFn attempts to obtain the value an attribute in the same group of attributes, which has not yet been added (on demand initialization).

Parameters:

cfgs Object

An object with attribute name/configuration pairs.
values Object

An object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.
lazy Boolean

Whether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See <a href="#method_addAttr">addAttr</a>.

`_addLazyAttr`

(

name

)

private

Inherited from AttributeCore: yui3/src/attribute/js/AttributeCore.js:360

Finishes initializing an attribute which has been lazily added.

Parameters:

name Object

The name of the attribute
[lazyCfg] Object optional

Optional config hash for the attribute. This is added for performance along the critical path, where the calling method has already obtained lazy config from state.

`_addOutOfOrder`

(

name

`destroy`

(

[options]
[callback]

)

chainable

Inherited from BaseObservable but overwritten in yui3/src/app/js/model.js:205

Destroys this model instance and removes it from its containing lists, if any. The callback, if one is provided, will be called after the model is destroyed. If <code>options.remove</code> is <code>true</code>, then this method delegates to the <code>sync()</code> method to delete the model from the persistence layer, which is an asynchronous action. In this case, the callback (if provided) will be called after the sync layer indicates success or failure of the delete operation.

Parameters:

[options] Object optional

Sync options. It's up to the custom sync implementation to determine what options it supports or requires, if any.
- [remove=false] Boolean optional
 
 If <code>true</code>, the model will be deleted via the sync layer in addition to the instance being destroyed.
[callback] Function optional

Called after the model has been destroyed (and deleted via the sync layer if <code>options.remove</code> is <code>true</code>).
- err Error | Null
 
 If an error occurred, this parameter will contain the error. Otherwise err will be <code>null</code>.

`detach`

(

type
fn
context

)

EventTarget

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:356

Detach one or more listeners the from the specified event

Parameters:

type String | Object

Either the handle to the subscriber or the type of event. If the type is not specified, it will attempt to remove the listener from all hosted events.
fn Function

The subscribed function to unsubscribe, if not supplied, all subscribers will be removed.
context Object

The custom object passed to subscribe. This is optional, but if supplied will be used to disambiguate multiple listeners that are the same (e.g., you subscribe many object using a function that lives on the prototype)

Returns:

EventTarget:

the host

`detachAll`

(

type

)

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:479

Removes all listeners from the specified event. If the event type is not specified, all listeners from all hosted custom events will be removed.

Parameters:

type String

The type, or name of the event

`fire`

(

type
arguments

)

Boolean

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:673

Fire a custom event by name. The callback functions will be executed from the context specified when the event was created, and with the following parameters.

The first argument is the event type, and any additional arguments are passed to the listeners as parameters. If the first of these is an object literal, and the event is configured to emit an event facade, that object is mixed into the event facade and the facade is provided in place of the original object.

If the custom event object hasn't been created, then the event hasn't been published and it has no subscribers. For performance sake, we immediate exit in this case. This means the event won't bubble, so if the intention is that a bubble target be notified, the event must be published on this object first.

Parameters:

type String | Object

The type of the event, or an object that contains a 'type' property.
arguments Object

an arbitrary set of parameters to pass to the handler. If the first of these is an object literal and the event is configured to emit an event facade, the event facade will replace that parameter after the properties the object literal contains are copied to the event facade.

Returns:

Boolean:

True if the whole lifecycle of the event went through, false if at any point the event propagation was halted.

`generateClientId`

() String

Inherited from Model: yui3/src/app/js/model.js:260

Returns a clientId string that's unique among all models on the current page (even models in other YUI instances). Uniqueness across pageviews is unlikely.

Returns:

String:

Unique clientId.

`get`

(

name

)

Any

Inherited from AttributeCore but overwritten in yui3/src/app/js/model.js:273

Returns the value of the specified attribute. If the attribute's value is an object, name may use dot notation to specify the path to a specific property within the object, and the value of that property will be returned.

Parameters:

name String

Attribute name or object property path.

Returns:

Any:

Attribute value, or <code>undefined</code> if the attribute doesn't exist.

Example:

<pre class="code prettyprint"><code>// Set the 'foo' attribute to an object. myModel.set('foo', { bar: { baz: 'quux' } }); // Get the value of 'foo'. myModel.get('foo'); // => {bar: {baz: 'quux'}} // Get the value of 'foo.bar.baz'. myModel.get('foo.bar.baz'); // => 'quux'</code></pre>

String:

URL-encoded attribute value.

`getAttrs`

(

attrs

)

Object

Inherited from AttributeCore: yui3/src/attribute/js/AttributeCore.js:803

Gets multiple attribute values.

Parameters:

attrs String | Boolean

Optional. An array of attribute names. If omitted, all attribute values are returned. If set to true, all attributes modified from their initial values are returned.

Returns:

Object:

An object with attribute name/value pairs.

`getEvent`

(

type
prefixed

)

CustomEvent

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:793

Returns the custom event of the provided type has been created, a falsy value otherwise

Parameters:

type String

the type, or name of the event
prefixed String

if true, the type is prefixed already

Returns:

CustomEvent:

the custom event or null

`getTargets`

()

Inherited from EventTarget: yui3/src/event-custom/js/event-facade.js:523

Returns an array of bubble targets for this object.

Returns:

EventTarget[]

`init`

(

cfg

)

BaseCore chainable

Inherited from BaseObservable but overwritten in yui3/src/base/js/BaseCore.js:319

Init lifecycle method, invoked during construction. Sets up attributes and invokes initializers for the class hierarchy.

Parameters:

cfg Object

Object with configuration property name/value pairs

Returns:

BaseCore:

A reference to this object

`isModified`

() Boolean

Inherited from Model: yui3/src/app/js/model.js:331

Returns <code>true</code> if any attribute of this model has been changed since the model was last saved. New models (models for which <code>isNew()</code> returns <code>true</code>) are implicitly considered to be "modified" until the first time they're saved.

Returns:

Boolean:

<code>true</code> if this model has changed since it was last saved, <code>false</code> otherwise.

`isNew`

() Boolean

Inherited from Model: yui3/src/app/js/model.js:346

Returns <code>true</code> if this model is "new", meaning it hasn't been saved since it was created. Newness is determined by checking whether the model's <code>id</code> attribute has been set. An empty id is assumed to indicate a new model, whereas a non-empty id indicates a model that was either loaded or has been saved since it was created.

Returns:

Boolean:

<code>true</code> if this model is new, <code>false</code> otherwise.

`load`

(

[options]
[callback]

)

chainable

Inherited from Model: yui3/src/app/js/model.js:362

Loads this model from the server. This method delegates to the <code>sync()</code> method to perform the actual load operation, which is an asynchronous action. Specify a callback function to be notified of success or failure. A successful load operation will fire a <code>load</code> event, while an unsuccessful load operation will fire an <code>error</code> event with the <code>src</code> value "load". If the load operation succeeds and one or more of the loaded attributes differ from this model's current attributes, a <code>change</code> event will be fired.

Parameters:

[options] Object optional

Options to be passed to <code>sync()</code> and to <code>set()</code> when setting the loaded attributes. It's up to the custom sync implementation to determine what options it supports or requires, if any.
[callback] Function optional

Called when the sync operation finishes.
- err Error | Null
 
 If an error occurred, this parameter will contain the error. If the sync operation succeeded, err will be <code>null</code>.
- response Any
 
 The server's response. This value will be passed to the <code>parse()</code> method, which is expected to parse it and return an attribute hash.

`modifyAttr`

(

name
config

)

Inherited from AttributeExtras: yui3/src/attribute/js/AttributeExtras.js:40

Updates the configuration of an attribute which has already been added. The properties which can be modified through this interface are limited to the following subset of attributes, which can be safely modified after a value has already been set on the attribute: <dl> <dt>readOnly;</dt> <dt>writeOnce;</dt> <dt>broadcast; and</dt> <dt>getter.</dt> </dl> Note: New attributes cannot be added using this interface. New attributes must be added using <a href="../classes/AttributeCore.html#method_addAttr" class="crosslink">addAttr</a>, or an appropriate manner for a class which utilises Attributes (e.g. the <a href="../classes/Base.html#property_ATTRS" class="crosslink">ATTRS</a> property in <a href="../classes/Base.html" class="crosslink">Base</a>).

Parameters:

name String

The name of the attribute whose configuration is to be updated.
config Object

An object with configuration property/value pairs, specifying the configuration properties to modify.

`on`

(

type
fn
[context]
[arg*]

)

EventHandle

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:188

Subscribe a callback function to a custom event fired by this object or from an object that bubbles its events to this object.

 this.on("change", this._onChange, this);

Callback functions for events published with emitFacade = true will receive an EventFacade as the first argument (typically named "e"). These callbacks can then call e.preventDefault() to disable the behavior published to that event's defaultFn. See the EventFacade API for all available properties and methods. Subscribers to non-emitFacade events will receive the arguments passed to fire() after the event name.

To subscribe to multiple events at once, pass an object as the first argument, where the key:value pairs correspond to the eventName:callback.

 this.on({
                                                     "attrChange" : this._onAttrChange,
                                                     "change"     : this._onChange
                                                 });

You can also pass an array of event names as the first argument to subscribe to all listed events with the same callback.

 this.on([ "change", "attrChange" ], this._onChange);

Returning false from a callback is supported as an alternative to calling e.preventDefault(); e.stopPropagation();. However, it is recommended to use the event methods whenever possible.

Parameters:

type String

The name of the event
fn Function

The callback to execute in response to the event
[context] Object optional

Override <code>this</code> object in callback
[arg*] Any optional

0..n additional arguments to supply to the subscriber

Returns:

EventHandle:

A subscription handle capable of detaching that subscription

fn
[context]
[arg*]

)

Parameters:

type String

The name of the event
fn Function

The callback to execute in response to the event
[context] Object optional

Override <code>this</code> object in callback
[arg*] Any optional

A subscription handle capable of detaching that subscription

`parse`

(

response

)

Object

Inherited from Model: yui3/src/app/js/model.js:434

Called to parse the response when the model is loaded from the server. This method receives a server response and is expected to return an attribute hash. The default implementation assumes that response is either an attribute hash or a JSON string that can be parsed into an attribute hash. If response is a JSON string and either <code>Y.JSON</code> or the native <code>JSON</code> object are available, it will be parsed automatically. If a parse error occurs, an <code>error</code> event will be fired and the model will not be updated. You may override this method to implement custom parsing logic if necessary.

Parameters:

response Any

Server response.

Returns:

Object:

Attribute hash.

`parseType`

(

type
[pre]

)

Array

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:168

Available since 3.3.0

Takes the type parameter passed to 'on' and parses out the various pieces that could be included in the type. If the event type is passed without a prefix, it will be expanded to include the prefix one is supplied or the event target is configured with a default prefix.

Parameters:

type String

the type
[pre] String optional

The prefix. Defaults to this._yuievt.config.prefix

Returns:

Array:

an array containing: <ul> <li>the detach category, if supplied,</li> <li>the prefixed event type,</li> <li>whether or not this is an after listener,</li> <li>the supplied event type</li> </ul>

`save`

(

[options]
[callback]

)

chainable

Inherited from Model: yui3/src/app/js/model.js:469

Saves this model to the server. This method delegates to the <code>sync()</code> method to perform the actual save operation, which is an asynchronous action. Specify a callback function to be notified of success or failure. A successful save operation will fire a <code>save</code> event, while an unsuccessful save operation will fire an <code>error</code> event with the <code>src</code> value "save". If the save operation succeeds and one or more of the attributes returned in the server's response differ from this model's current attributes, a <code>change</code> event will be fired.

Parameters:

[options] Object optional

Options to be passed to <code>sync()</code> and to <code>set()</code> when setting synced attributes. It's up to the custom sync implementation to determine what options it supports or requires, if any.
[callback] Function optional

Called when the sync operation finishes.
- err Error | Null
 
 If an error occurred or validation failed, this parameter will contain the error. If the sync operation succeeded, err will be <code>null</code>.
- response Any
 
 The server's response. This value will be passed to the <code>parse()</code> method, which is expected to parse it and return an attribute hash.

(

name
value
[options]

)

chainable

Inherited from AttributeObservable but overwritten in yui3/src/app/js/model.js:550

Sets the value of a single attribute. If model validation fails, the attribute will not be set and an <code>error</code> event will be fired. Use <code>setAttrs()</code> to set multiple attributes at once.

Parameters:

name String

Attribute name or object property path.
value Any

Value to set.
[options] Object optional

Data to be mixed into the event facade of the <code>change</code> event(s) for these attributes.

Parameters:

attributes Object

Hash of attribute names and values to set.
[options] Object optional

Data to be mixed into the event facade of the <code>change</code> event(s) for these attributes.
- [silent=false] Boolean optional
 
 If <code>true</code>, no <code>change</code> event will be fired.

`subscribe`

() deprecated

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:346

Deprecated: use on

subscribe to an event

`sync`

(

action
[options]
[callback]

)

Inherited from Model: yui3/src/app/js/model.js:656

Override this method to provide a custom persistence implementation for this model. The default just calls the callback without actually doing anything. This method is called internally by <code>load()</code>, <code>save()</code>, and <code>destroy()</code>, and their implementations rely on the callback being called. This effectively means that when a callback is provided, it must be called at some point for the class to operate correctly.

Parameters:

action String

Sync action to perform. May be one of the following: <ul> <li><code>create</code>: Store a newly-created model for the first time.</li> <li><code>delete</code>: Delete an existing model.</li> <li><code>read</code> : Load an existing model.</li> <li><code>update</code>: Update an existing model.</li> </ul>
[options] Object optional

Sync options. It's up to the custom sync implementation to determine what options it supports or requires, if any.
[callback] Function optional

Called when the sync operation finishes.
- err Error | Null
 
 If an error occurred, this parameter will contain the error. If the sync operation succeeded, err will be falsy.
- [response] Any optional
 
 The server's response.

`toJSON`

() Object

Inherited from Model: yui3/src/app/js/model.js:689

Returns a copy of this model's attributes that can be passed to <code>Y.JSON.stringify()</code> or used for other nefarious purposes. The <code>clientId</code> attribute is not included in the returned object. If you've specified a custom attribute name in the <code>idAttribute</code> property, the default <code>id</code> attribute will not be included in the returned object. Note: The ECMAScript 5 specification states that objects may implement a <code>toJSON</code> method to provide an alternate object representation to serialize when passed to <code>JSON.stringify(obj)</code>. This allows class instances to be serialized as if they were plain objects. This is why Model's <code>toJSON</code> returns an object, not a JSON string. See <a href="http://es5.github.com/#x15.12.3">http://es5.github.com/#x15.12.3</a> for details.

Returns:

Object:

Copy of this model's attributes.

`toString`

() String

Inherited from BaseCore: yui3/src/base/js/BaseCore.js:815

Default toString implementation. Provides the constructor NAME and the instance guid, if set.

Returns:

String:

String representation for this object

`undo`

(

[attrNames]
[options]

)

chainable

Inherited from Model: yui3/src/app/js/model.js:723

Reverts the last change to the model. If an attrNames array is provided, then only the named attributes will be reverted (and only if they were modified in the previous change). If no attrNames array is provided, then all changed attributes will be reverted to their previous values. Note that only one level of undo is available: from the current state to the previous state. If <code>undo()</code> is called when no previous state is available, it will simply do nothing.

Parameters:

[attrNames] String optional

Array of specific attribute names to revert. If not specified, all attributes modified in the last change will be reverted.
[options] Object optional

Data to be mixed into the event facade of the change event(s) for these attributes.
- [silent=false] Boolean optional
 
 If <code>true</code>, no <code>change</code> event will be fired.

`unsubscribe`

() deprecated

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:469

Deprecated: use detach

detach a listener

`unsubscribeAll`

(

type

)

deprecated

Inherited from EventTarget: yui3/src/event-custom/js/event-target.js:490

Deprecated: use detachAll

Removes all listeners from the specified event. If the event type is not specified, all listeners from all hosted custom events will be removed.

Parameters:

type String

The type, or name of the event

`validate`

(

attrs
callback

)

Inherited from Model: yui3/src/app/js/model.js:766

Override this method to provide custom validation logic for this model. While attribute-specific validators can be used to validate individual attributes, this method gives you a hook to validate a hash of all attributes before the model is saved. This method is called automatically before <code>save()</code> takes any action. If validation fails, the <code>save()</code> call will be aborted. In your validation method, call the provided <code>callback</code> function with no arguments to indicate success. To indicate failure, pass a single argument, which may contain an error message, an array of error messages, or any other value. This value will be passed along to the <code>error</code> event.

Parameters:

attrs Object

Attribute hash containing all model attributes to be validated.
callback Function

Validation callback. Call this function when your validation logic finishes. To trigger a validation failure, pass any value as the first argument to the callback (ideally a meaningful validation error of some kind).
- [err] Any optional
 
 Validation error. Don't provide this argument if validation succeeds. If validation fails, set this to an error message or some other meaningful value. It will be passed along to the resulting <code>error</code> event.

Example:

<pre class="code prettyprint"><code>model.validate = function (attrs, callback) { if (attrs.pie !== true) { // No pie?! Invalid! callback('Must provide pie.'); return; } <pre><code>// Success! callback(); </code></pre> };</code></pre>
