Twitter Bootstrap Ajax Typeahead Plugin

Modifications to the Bootstrap Typeahead plugin to give it ajax capabilities. See Demo

How to Use

To make a regular typeahead plugin query a server for the source, just specify an ajax member when initializing.

Feature

• A callback function is available for when an item is selected
• Ability to specify data source properties
• Ability to use a local or remote (AJAX) data source

Ajax Options

Name	Type	Default	Description
url	string	null	</td> </tr> <tr> <td> timeout </td> <td> integer </td> <td> 300 </td> <td> Specify the amount of time to wait for keyboard input to stop until you send the query to the server. Default is at 300ms. </td> </tr> <tr> <td> method </td> <td> string </td> <td> 'get' </td> <td> The method to use, either "post" or "get". </td> </tr> <tr> <td> triggerLength </td> <td> integer </td> <td> 1 </td> <td> This is the minimum length of text to take action on. Default is at 1. </td> </tr> <tr> <td> loadingClass </td> <td> string </td> <td> null </td> <td> </td> </tr> <tr> <td> preDispatch </td> <td> function </td> <td> null </td> <td> This function will be run prior to any call. It is used to fashion a custom parameter object to send to the server. Its only argument is the query text. It must return an object that jQuery's post() function will use as its second argument. There's no default for this. If not specified, the parameters send to the server are: <pre> { query: "some text" } </pre> </td> </tr> <tr> <td> preProcess </td> <td> function </td> <td> null </td> <td> This function will be run right after a call and before the typeahead list is populated. It is used to pre process the data returned from the server. Its only argument is the data from the server. Returning false from this method will hide the typeahead list. If not specified, the data will be passed to the typeahead mechanism as is. </td> </tr> <tr> <td> displayField </td> <td> string </td> <td> 'name' </td> <td> If the data returned from the server is a list of objects (as opposed to an array of strings), set this member to the name for the field to use for display. </td> </tr> <tr> <td> valueField </td> <td> string </td> <td> 'id' </td> <td> If the data returned from the server is a list of objects (as opposed to an array of strings), set this member to the id data for the item into list (*required* for a list of objects). </td> </tr>

Basic Usage

The plugin in its simplest (realistic) form.

Example 1

var typeaheadSource = ['John', 'Alex', 'Terry'];

$('input.typeahead').typeahead({
	source: typeaheadSource
});

Example 2

var typeaheadSource = [{ id: 1, name: 'John'}, { id: 2, name: 'Alex'}, { id: 3, name: 'Terry'}];

$('input.typeahead').typeahead({
	source: typeaheadSource
});

Example 3

var typeaheadSource = [{ 
         id: 1, firstName: 'John'}, { 
         id: 2, firstName: 'Alex'}, { 
         id: 3, firstName: 'Terry'
    }];

$('input.typeahead').typeahead({
        source: typeaheadSource,
        displayField: 'firstName'
});

Example 4

For a quick setup, specify a source url to pull data from:

$('input.typeahead').typeahead({
        ajax: '/path/to/typeahead/source'
});

Extended Usage

$("input.typeahead").typeahead({
	onSelect: function(item) {
		console.log(item);
	},
	ajax: {
		url: "/path/to/source",
		timeout: 500,
		displayField: "title",
		triggerLength: 1,
		method: "get",
		loadingClass: "loading-circle",
		preDispatch: function (query) {
			showLoadingMask(true);
			return {
				search: query
			}
		},
		preProcess: function (data) {
			showLoadingMask(false);
			if (data.success === false) {
				// Hide the list, there was some error
				return false;
			}
			// We good!
			return data.mylist;
		}
	}
});

Bootstrap Integration

For simple autocomplete use cases, the typeahead component [Bootstrap][bootstrap] provides should suffice. However, if you'd prefer to take advantage of some of the advance features typeahead.js provides, here's what you'll need to do to integrate typeahead.js with Bootstrap:

• If you're customizing Bootstrap, exclude the typeahead component. If you're depending on the standard bootstrap.js, ensure bootstrap-typeahead.js is loaded after it.
• The DOM structure of the dropdown menu used by typeahead.js differs from the DOM structure of the Bootstrap dropdown menu. You'll need to load some [additional CSS][typeahead-bootstrap.css] in order to get the bootstrap-typeahead.js dropdown menu to fit the default Bootstrap theme.
