jQuery Smart Auto Complete plugin
Requirements
jQuery 1.5 or above
Usage
In the header section of your page, add two script tags referencing to core jQuery and smart autocomplete plugin. It should look similar to code below:
<script src="jquery.js" type="text/javascript"></script>
<script src="jquery.smart_autocomplete.js" type="text/javascript"></script>
To activate the plugin call smartAutoComplete method with options on target jQuery object.
<script type="text/javascript">
$(function(){
$(target).smartAutoComplete({options})
});
</script>
Options
minCharLimit (integer)
default: 1
Sets the minimum characters user have to type before invoking the autocomplete
maxCharLimit (integer)
default: unlimited
Sets the maximum character range auto-complete will offer suggestions. Useful in free-form fields.
maxResults (integer)
default: null (means unlimited)
Sets the maximum number of results to return.
delay (integer)
default: 0
Sets the number of miliseconds plugin should wait, before calling the filter function.
disabled (boolean)
default: false
Sets whether autocomplete is disabled on the field.
forceSelect (boolean)
default: false
If set to true, field will be always filled with best matching result, without leaving the custom input. Better to enable this option, if you want autocomplete field to behave similar to a HTML select field. (Check Example 2 in the demo)
typeAhead (boolean)
default: false
If set to true, it will offer the best matching result in grey within the field; that can be auto-completed by pressing the right arrow-key or enter. This is similar to behaviour in Google Instant Search's query field (Check Example 3 in the demo)
source (string/array)
Defines the list of items to be filtered. You can give a hardcoded array or a string containing a URL, which will return a JSON array, as the source.
Note: Your can omit this option or provide a different object, if you are defining your own filter method.
filter (function)
parameters available: term, source
Define a custom function that would return the matching items for the term (this will override the default filtering algorithm) Function should return an array or a Deferred object (ajax call)
resultFormatter (function)
parameters available: result
The function you supply here will be called to format the output of an individual result. Function should return a string
resultsContainer (selector)
Define to which element(s) the results should be appended.
resultElement (selector)
References the result elements collection. It should be a jQuery selector which could capture all result elements within the results container (e.g. li, div.result).
Events
Following custom events will be available to the element which has smartAutoComplete activated. You can bind handlers to these events like other jQuery events and also cancel the default handler by calling event.preventDefault().
Note: Make sure you bind the handlers, only after smartAutoComplete is activated on the field. Otherwise context data could get overriden.
To learn more about the default behaviour of the events, please refer to the specs at spec/core/jquery.smart_autocomplete_spec.js.
