Methods

Methods

_addAttrs

(
  • cfgs
  • values
  • lazy
)
private
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 addAttr.

_addLazyAttr

(
  • name
  • [lazyCfg]
)
private
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
  • cfg
)
private
Utility method used by get/set to add attributes encountered out of order when calling addAttrs(). For example, if: this.addAttrs({ foo: { setter: function() { // make sure this bar is available when foo is added this.get("bar"); } }, bar: { value: ... } });

Parameters:

  • name String
    attribute name
  • cfg Object
    attribute configuration

_addShimResizeHandlers

() private
Sets up event listeners to resize the shim when the size of the Widget changes.

Returns:

Object: The set of adhoc attributes passed in, in the form of an object with attribute name/configuration pairs.

_filterUIEvent

(

Boolean private
This method is used to determine if we should fire the UI Event or not. The default implementation makes sure that for nested delegates (nested unrelated widgets), we don't fire the UI event listener more than once at each level.

For example, without the additional filter, if you have nested widgets, each widget will have a delegate listener. If you click on the inner widget, the inner delegate listener's filter will match once, but the outer will match twice (based on delegate's design) - once for the inner widget, and once for the outer.

Parameters:

Returns:

Boolean: true if it's OK to fire the custom UI event, false if not.

Parameters:

addAttr

(
  • name
  • config
  • lazy
)
Object chainable

Adds an attribute with the provided configuration to the host object.

The config argument object supports the following properties:

value <Any>
The initial value to set on the attribute
valueFn <Function | String>

A function, which will return the initial value to set on the attribute. This is useful for cases where the attribute configuration is defined statically, but needs to reference the host instance ("this") to obtain an initial value. If both the value and valueFn properties are defined, the value returned by the valueFn has precedence over the value property, unless it returns undefined, in which case the value property is used.

valueFn can also be set to a string, representing the name of the instance method to be used to retrieve the value.

readOnly <boolean>
Whether or not the attribute is read only. Attributes having readOnly set to true cannot be modified by invoking the set method.
writeOnce <boolean> or <string>
Whether or not the attribute is "write once". Attributes having writeOnce set to true, can only have their values set once, be it through the default configuration, constructor configuration arguments, or by invoking set.

The writeOnce attribute can also be set to the string "initOnly", in which case the attribute can only be set during initialization (when used with Base, this means it can only be set during construction)

setter <Function | String>

The setter function used to massage or normalize the value passed to the set method for the attribute. The value returned by the setter will be the final stored value. Returning Attribute.INVALID_VALUE, from the setter will prevent the value from being stored.

setter can also be set to a string, representing the name of the instance method to be used as the setter function.

getter <Function | String>

The getter function used to massage or normalize the value returned by the get method for the attribute. The value returned by the getter function is the value which will be returned to the user when they invoke get.

getter can also be set to a string, representing the name of the instance method to be used as the getter function.

validator <Function | String>

The validator function invoked prior to setting the stored value. Returning false from the validator function will prevent the value from being stored.

validator can also be set to a string, representing the name of the instance method to be used as the validator function.

lazyAdd <boolean>
Whether or not to delay initialization of the attribute until the first call to get/set it. This flag can be used to over-ride lazy initialization on a per attribute basis, when adding multiple attributes through the addAttrs method.

The setter, getter and validator are invoked with the value and name passed in as the first and second arguments, and with the context ("this") set to the host object.

Configuration properties outside of the list mentioned above are considered private properties used internally by attribute, and are not intended for public use.

Parameters:

  • name String
    The name of the attribute.
  • config Object
    An object with attribute configuration property/value pairs, specifying the configuration for the attribute.

    NOTE: The configuration object is modified when adding an attribute, so if you need to protect the original values, you will need to merge the object.

  • lazy Boolean
    (optional) Whether or not to add this attribute lazily (on the first call to get/set).

Returns:

Object: A reference to the host object.

addAttrs

(
  • cfgs
  • values
  • lazy
)
Object chainable
Configures a group of attributes, and sets initial values.

NOTE: This method does not isolate the configuration object by merging/cloning. The caller is responsible for merging/cloning the configuration object if required.

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 addAttr.

Returns:

Object: A reference to the host object.

addTarget

(
  • o
)
chainable
Registers another EventTarget as a bubble target. Bubble order is determined by the order registered. Multiple targets can be specified. Events can only bubble if emitFacade is true. Included in the event-custom-complex submodule.

Parameters:

    The callback to execute in response to the event
  • [context] Object optional
    Override this object in callback

EventHandle: A subscription handle capable of detaching the subscription

align

(
  • [node]
  • [points]
)
chainable

Parameters:

  • [node] Node | String | Null optional
    A reference (or selector String) for the Node which with the widget is to be aligned. If null is passed in, the widget will be aligned with the viewport.
  • [points] Array2 optional
    A two item array specifying the points on the widget and Node/viewport which will to be aligned. The first entry is the point on the widget, and the second entry is the point on the Node/viewport. Valid point references are defined as static constants on the WidgetPositionAlign extension.

constrain

(
  • xy
  • node
)

    Optional. The xy values to constrain
  • node Node | boolean
    Optional. The node to constrain to, or true for the viewport

destroy

(
  • destroyAllNodes
)
Widget chainable

Inherited from BaseObservable but overwritten in widget/js/Widget.js:448

Destroy lifecycle method. Fires the destroy event, prior to invoking destructors for the class hierarchy. Overrides Base's implementation, to support arguments to destroy

Subscribers to the destroy event can invoke preventDefault on the event object, to prevent destruction from proceeding.

Parameters:

  • destroyAllNodes Boolean
    If true, all nodes contained within the Widget are removed and destroyed. Defaults to false due to potentially high run-time cost.

Returns:

Widget: A reference to this object

destructor

() protected
Destructor lifecycle implementation for the Widget class. Purges events attached to the bounding box and content box, removes them from the DOM and removes the Widget from the list of registered widgets.

detach

(
  • type
  • fn
  • context
)
EventTarget
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
)
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

disable

() chainable
Set the Widget's "disabled" attribute to "true".

enable

() chainable
Set the Widget's "disabled" attribute to "false".

fillHeight

(
  • node
)
Sets the height on the provided header, body or footer element to fill out the height of the Widget. It determines the height of the widgets bounding box, based on it's configured height value, and sets the height of the provided section to fill out any space remaining after the other standard module section heights have been accounted for.

NOTE: This method is not designed to work if an explicit height has not been set on the Widget, since for an "auto" height Widget, the heights of the header/body/footer will drive the height of the Widget.

Parameters:

  • node Node
    The node which should be resized to fill out the height of the Widget bounding box. Should be a standard module section node which belongs to the widget.

fire

(
  • type
  • arguments
)
Boolean
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.

focus

() chainable
Causes the Widget to receive the focus by setting the "focused" attribute to "true".

get

(

Any
Returns the current value of the attribute. If the attribute has been configured with a 'getter' function, this method will delegate to the 'getter' to obtain the value of the attribute.

Parameters:

  • name String
    The name of the attribute. If the value of the attribute is an Object, dot notation can be used to obtain the value of a property of the object (e.g. get("x.y.z"))

Returns:

Any: The value of the attribute

getAttrs

(
  • attrs
)
Object
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.

getClassName

(

Inherited from Widget but overwritten in widget/js/Widget.js:309

Generate a standard prefixed classname for the Widget, prefixed by the default prefix defined by the Y.config.classNamePrefix attribute used by ClassNameManager and Widget.NAME.toLowerCase() (e.g. "yui-widget-xxxxx-yyyyy", based on default values for the prefix and widget class name).

The instance based version of this method can be used to generate standard prefixed classnames, based on the instances NAME, as opposed to Widget.NAME. This method should be used when you need to use a constant class name across different types instances.

Parameters:

  • args String multiple
    0..n strings which should be concatenated, using the default separator defined by ClassNameManager, to create the class name

getConstrainedXY

(
  • xy

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

getSkinName

(
  • [skinPrefix]
)
String
Returns the name of the skin that's currently applied to the widget. Searches up the Widget's ancestor axis for, by default, a class yui3-skin-(name), and returns the (name) portion. Otherwise, returns null. This is only really useful after the widget's DOM structure is in the document, either by render or by progressive enhancement.

Parameters:

  • [skinPrefix] String optional
    The prefix which the implementation uses for the skin ("yui3-skin-" is the default). NOTE: skinPrefix will be used as part of a regular expression: new RegExp('\\b' + skinPrefix + '(\\S+)') Although an unlikely use case, literal characters which may result in an invalid regular expression should be escaped.

Returns:

String: The name of the skin, or null, if a matching skin class is not found.

getStdModNode

Node
Returns the node reference for the specified section. **Note:** The DOM is not queried for the node reference. The reference stored by the widget instance is returned if it was set. Passing a truthy for forceCreate will create the section node if it does not already exist.

Parameters:

  • section String
    The section whose node reference is required. Either WidgetStdMod.HEADER, WidgetStdMod.BODY, or WidgetStdMod.FOOTER.
  • forceCreate Boolean
    Whether the section node should be created if it does not already exist.

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:

readOnly;
writeOnce;
broadcast; and
getter.

Note: New attributes cannot be added using this interface. New attributes must be added using {{#crossLink "AttributeCore/addAttr:method"}}addAttr{{/crossLink}}, or an appropriate manner for a class which utilises Attributes (e.g. the {{#crossLink "Base/ATTRS:property"}}ATTRS{{/crossLink}} property in {{#crossLink "Base"}}Base{{/crossLink}}).

on

(
  • type
  • fn
  • [context]
  • [arg*]
)
EventHandle
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 this object in callback

final chainable
Establishes the initial DOM for the widget. Invoking this method will lead to the creating of all DOM elements for the widget (or the manipulation of existing DOM elements for the progressive enhancement use case).

This method should only be invoked once for an initialized widget.

It delegates to the widget specific renderer method to do the actual work.

Parameters:

  • parentNode Object | String
    Optional. The Node under which the Widget is to be rendered. This can be a Node instance or a CSS selector string.

    If the selector string returns more than one Node, the first node will be used as the parentNode. NOTE: This argument is required if both the boundingBox and contentBox are not currently in the document. If it's not provided, the Widget will be rendered to the body of the current document in this case.

renderer

() protected
Creates DOM (or manipulates DOM for progressive enhancement) This method is invoked by render() and is not chained automatically for the class hierarchy (unlike initializer, destructor) so it should be chained manually for subclasses if required.

Returns:

Object: A reference to the host object.

set

(
  • name
  • value
  • [opts]
)
Object chainable
Sets the value of an attribute.

Parameters:

  • value Any
    The value to set the attribute to.
  • [opts] Object optional
    Optional data providing the circumstances for the change.

Returns:

Object: A reference to the host object.

Returns:

Object: A reference to the host object.

setStdModContent

(
  • section
  • content
  • where
)
Updates the body section of the standard module with the content provided (either an HTML string, or node reference).

This method can be used instead of the corresponding section content attribute if you'd like to retain the current content of the section, and insert content before or after it, by specifying the where argument.

Parameters:

  • section String
    The standard module section whose content is to be updated. Either WidgetStdMod.HEADER, WidgetStdMod.BODY or WidgetStdMod.FOOTER.
  • content String | Node
    The content to be added, either an HTML string or a Node reference.

The alignOn Attribute is expected to be an Array of Objects with the following properties: * __eventName__: The String event name to listen for. * __node__: The optional Node that will fire the event, it can be a Node reference or a selector String. This will default to the widget's boundingBox.

Default: []

Example:

Sync this widget's alignment on window resize:

myWidget.set('alignOn', [
                        {

Default: null

visible

Boolean
Boolean indicating whether or not the Widget is visible.

Events

destroy

Lifecycle event for the destroy phase, fired prior to destruction. Invoking the preventDefault method on the event object provided to subscribers will prevent destruction from proceeding.

Subscribers to the "after" moment of this event, will be notified after destruction is complete (and as a result cannot prevent destruction).

Event Payload:

init

Lifecycle event for the init phase, fired prior to initialization. Invoking the preventDefault() method on the event object provided to subscribers will prevent initialization from occuring.

Subscribers to the "after" momemt of this event, will be notified after initialization of the object is complete (and therefore cannot prevent initialization).

Event Payload:

  • e EventFacade
    Event object, with a cfg property which refers to the configuration object passed to the constructor.

render

Lifecycle event for the render phase, fired prior to rendering the UI for the widget (prior to invoking the widget's renderer method).

Subscribers to the "on" moment of this event, will be notified before the widget is rendered.

Subscribers to the "after" moment of this event, will be notified after rendering is complete.

Event Payload:

widget:contentUpdate

Notification event, which widget implementations can fire, when they change the content of the widget. This event has no default behavior and cannot be prevented, so the "on" or "after" moments are effectively equivalent (with on listeners being invoked before after listeners).

Event Payload:
