_doAlign
-
widgetPoint -
x -
y
Helper method, used to align the given point on the widget, with the XY page coordinates provided.
_filterAdHocAttrs
-
allAttrs -
userVals
Parameters:
-
allAttrsObjectThe set of all attribute configurations for this instance. Attributes will be removed from this set, if they belong to the filtered class, so that by the time all classes are processed, allCfgs will be empty.
-
userValsObjectThe config object passed in by the user, from which adhoc attrs are to be filtered.
Returns:
_filterAttrCfs
-
clazz -
allCfgs
A helper method used when processing ATTRS across the class hierarchy during initialization. Returns a disposable object with the attributes defined for the provided class, extracted from the set of all attributes passed in.
Parameters:
Returns:
_filterUIEvent
-
evt
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:
-
evtDOMEventFacade
Returns:
_fireAttrChange

Returns:
_getObjectValue
-
obj -
path
Faster and safer alternative to Y.Object.getValue(). Doesn't bother
casting the path to an array (since we already know it's an array) and
doesn't throw an error if a value in the middle of the object hierarchy is
neither undefined nor an object.

addAttr
-
name -
config -
lazy
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:
-
nameStringThe name of the attribute.
-
configObjectAn 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.
-
lazyBoolean(optional) Whether or not to add this attribute lazily (on the first call to get/set).
Returns:
addAttrs
-
cfgs -
values -
lazy
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:
-
cfgsObjectAn object with attribute name/configuration pairs.
-
valuesObjectAn 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.
-
lazyBooleanWhether 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:
addTarget
-
o

Parameters:
Returns:
align
-
[node] -
[points]
Aligns this widget to the provided Node (or viewport) using the provided
points. This method can be invoked with no arguments which will cause the
widget's current align Attribute value to be synced to the DOM.
Parameters:
-
[node]Node | String | Null optionalA reference (or selector String) for the
Nodewhich with the widget is to be aligned. If null is passed in, the widget will be aligned with the viewport. -

destroy
-
destroyAllNodes
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:
-
destroyAllNodesBooleanIf true, all nodes contained within the Widget are removed and destroyed. Defaults to false due to potentially high run-time cost.
Returns:

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
Detach one or more listeners the from the specified event
Parameters:
-
typeString | ObjectEither 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.
-
fnFunctionThe subscribed function to unsubscribe, if not supplied, all subscribers will be removed.
-

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:
-
typeStringThe type, or name of the event

fire
-
type -
arguments
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.
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.
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.
Parameters:
-
typeString | ObjectThe type of the event, or an object that contains a 'type' property.
-
argumentsObject*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:
focus
()
chainable
Causes the Widget to receive the focus by setting the "focused" attribute to "true".
get
-
name
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:
-
nameStringThe 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:
getAttrs
-
attrs

Parameters:
-
attrsArray | booleanOptional. 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.

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:
-
argsString* multiple0..n strings which should be concatenated, using the default separator defined by ClassNameManager, to create the class name
getDefaultLocale

[context] -
[arg*]
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:
Returns:
once

render
-
parentNode
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:
-
parentNodeObject | StringOptional. 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
Resets the attribute (or all attributes) to its initial value, as long as the attribute is not readOnly, or writeOnce.

-
[originEvent]EventFacade optionalEvent that triggered the selection, if any.
sendRequest
-
[query] -
[requestTemplate]
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 optionalQuery to send. If specified, the
queryattribute will be set to this query. If not specified, the current value of thequeryattribute will be used. -

Parameters:
-
eEventFacadeAn Event Facade object with the following attribute-specific properties added:
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:
-
eEventFacadeAn Event Facade object with the following attribute-specific properties added:
results
Array
readonly
Current results, or an empty array if there are no results.
Default: []
Fires event resultsChange
Fires when the value for the configuration attribute results 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:
-
eEventFacadeAn Event Facade object with the following attribute-specific properties added:
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.

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:
-
eEventFacadeAn Event Facade object with the following attribute-specific properties added:
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.
Example:
['first result', 'second result', 'etc'] - DataSource
-
A
DataSourceinstance or other object that provides a DataSource-likesendRequestmethod. See theDataSourcedocumentation 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).
Example (synchronous):
function (query) { return ['foo', 'bar']; }Example (async):
function (query, callback) { callback(['foo', 'bar']); } - 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.
The response is assumed to be an array of results by default. If the response is not an array, provide a
resultListLocatorto process the response and return an array.Example:
{foo: ['foo result 1', 'foo result 2'], bar: ['bar result']}
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
resultTextLocatorof '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).The response is assumed to be an array of results by default. If the response is not an array, provide a
resultListLocatorto process the response and return an array.The
jsonpmodule must be loaded in order for JSONP URL sources to work. If thejsonpmodule is not already loaded, it will be loaded on demand if possible.Example:
'http://example.com/search?q={query}&callback={callback}' - 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).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
resultListLocatorto 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.The
io-baseandjson-parsemodules must be loaded in order for XHR URL sources to work. If these modules are not already loaded, they will be loaded on demand if possible.Example:
'http://example.com/search?q={query}' - 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).The
yqlmodule must be loaded in order for YQL sources to work. If theyqlmodule is not already loaded, it will be loaded on demand if possible.Example:
'select * from search.suggest where query="{query}"'
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.
