AutoCompleteBase Class
Extension that provides core autocomplete logic (but no UI implementation) for a text input field or textarea.
The AutoCompleteBase class provides events and attributes that abstract away
core autocomplete logic and configuration, but does not provide a widget
implementation or suggestion UI. For a prepackaged autocomplete widget, see
AutoCompleteList.
This extension cannot be instantiated directly, since it doesn't provide an
actual implementation. It's intended to be mixed into a Y.Base-based class or
widget.
Y.Widget-based example:
YUI().use('autocomplete-base', 'widget', function (Y) {
    var MyAC = Y.Base.create('myAC', Y.Widget, [Y.AutoCompleteBase], {
        // Custom prototype methods and properties.
    }, {
        // Custom static methods and properties.
    });
    // Custom implementation code.
});
Y.Base-based example:
YUI().use('autocomplete-base', function (Y) {
    var MyAC = Y.Base.create('myAC', Y.Base, [Y.AutoCompleteBase], {
        initializer: function () {
            this._bindUIACBase();
            this._syncUIACBase();
        },
        // Custom prototype methods and properties.
    }, {
        // Custom static methods and properties.
    });
    // Custom implementation code.
});

specified object, and returns the found value (if any) as a response. See
the source attribute for more details.
Parameters:
-

the specified YQL query for results. If the string starts with "select ",
"use ", or "set " (case-insensitive), it's assumed to be a YQL query;
otherwise, it's assumed to be a URL (which may be absolute or relative).
URLs containing a "{callback}" placeholder are assumed to be JSONP URLs; all
others will use XHR. See the source attribute for more details.

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.
- 
                    
                        [requestTemplate]Function optionalRequest template function. If not specified, the current value of the requestTemplateattribute will be used.

    Current query, or null if there is no current query.
The query might not be the same as the current value of the input node, both
for timing reasons (due to queryDelay) and because when one or more
queryDelimiter separators are in use, only the last portion of the
delimited input string will be used as the query value.

queryDelay
    Number
    
    
    
    
    
    Number of milliseconds to delay after input before triggering a query
event. If new input occurs before this delay is over, the previous input
event will be ignored and a new delay will begin.
This can be useful both to throttle queries to a remote data source and to avoid distracting the user by showing them less relevant results before they've paused their typing.
Default: 100
Fires event queryDelayChange
            
            Fires when the value for the configuration attribute queryDelay 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:
queryDelimiter
    String | Null
    
    
    
    
    
    Query delimiter string. When a delimiter is configured, the input value
will be split on the delimiter, and only the last portion will be used in
autocomplete queries and updated when the query attribute is
modified.
Default: null
Fires event queryDelimiterChange
            
            Fires when the value for the configuration attribute queryDelimiter 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:
requestTemplate
    Function | String | Null
    
    
    
    
    
    Source request template. This can be a function that accepts a query as a
parameter and returns a request string, or it can be a string containing the
placeholder "{query}", which will be replaced with the actual URI-encoded
query. In either case, the resulting string will be appended to the request
URL when the source attribute is set to a remote DataSource, JSONP URL, or
XHR URL (it will not be appended to YQL URLs).
While requestTemplate may be set to either a function or a string, it will
always be returned as a function that accepts a query argument and returns a
string.
Default: null
Fires event requestTemplateChange
            
            Fires when the value for the configuration attribute requestTemplate 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:
resultFilters
    Array
    
    
    
    
    
    Array of local result filter functions. If provided, each filter will be
called with two arguments when results are received: the query and an array
of result objects. See the documentation for the results event for a list
of the properties available on each result object.
Each filter is expected to return a filtered or modified version of the
results array, which will then be passed on to subsequent filters, then the
resultHighlighter function (if set), then the resultFormatter function
(if set), and finally to subscribers to the results event.
If no source is set, result filters will not be called.
Prepackaged result filters provided by the autocomplete-filters and
autocomplete-filters-accentfold modules can be used by specifying the filter
name as a string, such as 'phraseMatch' (assuming the necessary filters
module is loaded).
Default: []
Fires event resultFiltersChange
            
            Fires when the value for the configuration attribute resultFilters 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:
resultFormatter
    Function | Null
    
    
    
    
    
    Function which will be used to format results. If provided, this function will be called with two arguments after results have been received and filtered: the query and an array of result objects. The formatter is expected to return an array of HTML strings or Node instances containing the desired HTML for each result.
See the documentation for the results event for a list of the properties
available on each result object.
If no source is set, the formatter will not be called.
Fires event resultFormatterChange
            
            Fires when the value for the configuration attribute resultFormatter 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.

            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:
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
    
    
    
    
    
    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.
Fires event resultTextLocatorChange
            
            Fires when the value for the configuration attribute resultTextLocator 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:
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.

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'.
