Methods

Methods

_activateNextItem

() protected chainable

Activates the next item after the currently active item. If there is no next item and the circular attribute is true, focus will wrap back to the input node.

_activatePrevItem

() protected chainable

Activates the item previous to the currently active item. If there is no previous item and the circular attribute is true, focus will wrap back to the input node.

_add

(
  • items
)
NodeList protected

Appends the specified result items to the list inside a new item node.

Parameters:

Returns:

NodeList :

Added nodes.

_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: {

 // make sure this bar is available when foo is added
 this.get("bar");
 }
 },
 bar: {
 value: ...
 }
});

  • userVals Object

    The config object passed in by the user, from which adhoc attrs are to be filtered.

Returns:

Object :

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

_filterUIEvent

(
  • evt
)
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

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.

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)

    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".

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"))

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+)')

Initializer lifecycle implementation for the Widget class. Registers the widget instance, and runs through the Widget's HTML_PARSER definition.

Parameters:

  • config Object

    Configuration object literal for the widget

isRoot

() Boolean

Determines if the Widget is the root Widget in the object hierarchy.

Returns:

Boolean :

Boolean indicating if Widget is the root Widget in the object hierarchy.

modifyAttr

(
  • name
  • config
)

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:

readOnly;
writeOnce;
broadcast; and
getter.

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

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.

move

(
  • x
  • [y]
)

Moves the Widget to the specified page xy co-ordinate position.

Parameters:

  • x Number | Number[]

    The new x position or [x, y] values passed as an array to support simple pass through of Node.getXY results

  • [y] Number optional

    The new y position

next

(
  • circular
)
Widget

Returns the Widget's next sibling.

Parameters:

  • circular Boolean

Widget instance.

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.

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, or pass an array of event names as the first argument to subscribe to all listed events with the same callback.

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

  • [arg*] Any optional

Parameters:

render

(
  • parentNode
)
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.

renderUI

() protected

Adds nodes to the DOM

This method is not called by framework and is not chained automatically for the class hierarchy.

reset

(
  • name
)
Object chainable

Resets the attribute (or all attributes) to its initial value, as long as the attribute is not readOnly, or writeOnce.

Parameters:

    Optional. The name of the attribute to reset. If omitted, all attributes are reset.

Returns:

Object :

A reference to the host object.

selectItem

(
  • [itemNode]
  • [originEvent]
)
chainable

Selects the specified itemNode, or the current activeItem if itemNode is not specified.

Parameters:

  • [itemNode] Node optional

    Item node to select.

  • [originEvent] EventFacade optional

    Event that triggered the selection, if any.

sendRequest

(
  • [query]
  • [requestTemplate]
)
chainable

Sends a request to the configured source. If no source is configured, this method won't do anything.

Usually there's no reason to call this method manually; it will be called automatically when user input causes a query event to be fired. The only time you'll need to call this method manually is if you want to force a request to be sent when no user input has occurred.

Parameters:

  • [query] String optional

    Query to send. If specified, the query attribute will be set to this query. If not specified, the current value of the query attribute will be used.

  • [requestTemplate] Function optional

    Request template function. If not specified, the current value of the requestTemplate attribute will be used.

set

(
  • name
  • value
  • [opts]
)
Object chainable

Sets the value of an attribute.

Parameters:

  • name String

    The name of the attribute. If the current value of the attribute is an Object, dot notation can be used to set the value of a property within the object (e.g. set("x.y.z", 5)).

  • 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.

query

String | Null readonly

Current query, or null if there is no current query.

resultListLocator

Function | String | Null

Locator that should be used to extract an array of results from a non-array response.

By default, no locator is applied, and all responses are assumed to be arrays by default. If all responses are already arrays, you don't need to define a locator.

The locator may be either a function (which will receive the raw response as an argument and must return an array) or a string representing an object path, such as "foo.bar.baz" (which would return the value of result.foo.bar.baz if the response is an object).

While resultListLocator may be set to either a function or a string, it will always be returned as a function that accepts a response argument and returns an array.

Fires event resultListLocatorChange

Fires when the value for the configuration attribute resultListLocator is changed. You can listen for the event using the on method if you wish to be notified before the attribute's value has changed, or using the after method if you wish to be notified after the attribute's value has changed.

Parameters:

      If setting a property within the attribute's value, the name of the sub-attribute property being set.

resultTextLocator

Function | String | Null

Locator that should be used to extract a plain text string from a non-string result item. The resulting text value will typically be the value that ends up being inserted into an input field or textarea when the user of an autocomplete implementation selects a result.

By default, no locator is applied, and all results are assumed to be plain text strings. If all results are already plain text strings, you don't need to define a locator.

The locator may be either a function (which will receive the raw result as an argument and must return a string) or a string representing an object path, such as "foo.bar.baz" (which would return the value of result.foo.bar.baz if the result is an object).

While resultTextLocator may be set to either a function or a string, it will always be returned as a function that accepts a result argument and returns a string.

source

Array | DataSource | Function | Node | Object | String | Null

Source for autocomplete results. The following source types are supported:

Array

The full array will be provided to any configured filters for each query. This is an easy way to create a fully client-side autocomplete implementation. 

<p>
Example: <code>[&#39;first result&#39;, &#39;second result&#39;, &#39;etc&#39;]</code>
</p>

DataSource
A DataSource instance or other object that provides a DataSource-like sendRequest method. See the DataSource documentation for details.

Function

A function source will be called with the current query and a callback function as parameters, and should either return an array of results (for synchronous operation) or return nothing and pass an array of results to the provided callback (for asynchronous operation). 

<p>
Example (synchronous):
</p>
<pre>
function (query) {
 return [&#39;foo&#39;, &#39;bar&#39;];
}
</pre>
<p>
Example (async):
</p>
<pre>
function (query, callback) {
 callback([&#39;foo&#39;, &#39;bar&#39;]);
}
</pre>

Object

An object will be treated as a query hashmap. If a property on the object matches the current query, the value of that property will be used as the response. 

<p>
The response is assumed to be an array of results by default. If the
response is not an array, provide a <code>resultListLocator</code> to
process the response and return an array.
</p>
<p>
Example: <code>{foo: [&#39;foo result 1&#39;, &#39;foo result 2&#39;], bar: [&#39;bar result&#39;]}</code>
</p>

If the optional autocomplete-sources module is loaded, then the following additional source types will be supported as well:

<select> Node
You may provide a YUI Node instance wrapping a <select> element, and the options in the list will be used as results. You will also need to specify a resultTextLocator of 'text' or 'value', depending on what you want to use as the text of the result. Each result will be an object with the following properties:
html (String)

HTML content of the <option> element.

index (Number)

Index of the <option> element in the list.

node (Y.Node)

Node instance referring to the original <option> element.

selected (Boolean)

Whether or not this item is currently selected in the <select> list.

text (String)

Text content of the <option> element.

value (String)

Value of the <option> element.

String (JSONP URL)

If a URL with a {callback} placeholder is provided, it will be used to make a JSONP request. The {query} placeholder will be replaced with the current query, and the {callback} placeholder will be replaced with an internally-generated JSONP callback name. Both placeholders must appear in the URL, or the request will fail. An optional {maxResults} placeholder may also be provided, and will be replaced with the value of the maxResults attribute (or 1000 if the maxResults attribute is 0 or less). 

<p>
The response is assumed to be an array of results by default. If the
response is not an array, provide a <code>resultListLocator</code> to process the
response and return an array.
</p>
<p>
<strong>The <code>jsonp</code> module must be loaded in order for
JSONP URL sources to work.</strong> If the <code>jsonp</code> module
is not already loaded, it will be loaded on demand if possible.
</p>
<p>
Example: <code>&#39;http://example.com/search?q={query}&amp;callback={callback}&#39;</code>
</p>

String (XHR URL)

If a URL without a {callback} placeholder is provided, it will be used to make a same-origin XHR request. The {query} placeholder will be replaced with the current query. An optional {maxResults} placeholder may also be provided, and will be replaced with the value of the maxResults attribute (or 1000 if the maxResults attribute is 0 or less). 

<p>
The response is assumed to be a JSON array of results by default. If the
response is a JSON object and not an array, provide a
<code>resultListLocator</code> to process the response and return an array. If the
response is in some form other than JSON, you will need to use a custom
DataSource instance as the source.
</p>
<p>
<strong>The <code>io-base</code> and <code>json-parse</code> modules
must be loaded in order for XHR URL sources to work.</strong> If
these modules are not already loaded, they will be loaded on demand
if possible.
</p>
<p>
Example: <code>&#39;http://example.com/search?q={query}&#39;</code>
</p>

String (YQL query)

If a YQL query is provided, it will be used to make a YQL request. The {query} placeholder will be replaced with the current autocomplete query. This placeholder must appear in the YQL query, or the request will fail. An optional {maxResults} placeholder may also be provided, and will be replaced with the value of the maxResults attribute (or 1000 if the maxResults attribute is 0 or less). 

<p>
<strong>The <code>yql</code> module must be loaded in order for YQL
sources to work.</strong> If the <code>yql</code> module is not
already loaded, it will be loaded on demand if possible.
</p>
<p>
Example: <code>&#39;select * from search.suggest where query=&quot;{query}&quot;&#39;</code>
</p>

As an alternative to providing a source, you could simply listen for query events and handle them any way you see fit. Providing a source is optional, but will usually be simpler.

Fires event sourceChange

Be warned that if you set this attribute and something breaks, it's your own fault.

Supported sourceType values are: 'array', 'datasource', 'function', and 'object'.
