jQuery UI Examples -Autocomplete

Search and filter based on user input values, allowing users to quickly find and select from a preset value list.

For more details about the autocomplete widget, please refer to the API documentation.Autocomplete Widget。

Used in this chaptersearch.php Download。

Default functionality

As you type in the input field, the Autocomplete widget provides corresponding suggestions. In this example, suggestions for programming languages are provided; you can try typing "ja" to get Java or JavaScript.

The datasource is a simple JavaScript array, provided to the widget via the source option.

Accent sensitivity

The autocomplete field uses a custom source option to match result items with accented characters, even if the text field does not contain accented characters. However, if you type accented characters in the text field, non-accented result items will not be displayed.

Try typing "Jo" to see "John" and "Jörn", then type "Jö" to see only "Jörn".

Combobox

A custom widget created from Autocomplete and Button. You can type some characters to get results filtered based on your input, or use the button to select from the full list.

The input is read from an existing select element and passed to Autocomplete with a custom source option.

This is an unsupported, imperfect widget. It is purely to demonstrate autocomplete customization features.For more details on how this widget works, click here to view the related jQuery article.

Custom data and display

You can use a custom data format and display the data by simply overriding the default focus and select behaviors.

Try typing "j", or press the down arrow key, to get a list of items.

Multiple values

Usage: type some characters, such as "j", to see related programming language results. Select a value, then continue typing characters to add other values.

This example demonstrates how to use the source option and some events to implement multiple autocomplete values in a single text field.

Multiple values, remote

Usage: type at least two characters to get bird names. Select a value, then continue typing characters to add other values.

Remote JSONP datasource

Usage: type at least two characters to get bird names. Select a value, then continue typing characters to add other values.

This example demonstrates how to use jsonp to fetch data.

Remote datasource

As you type characters in the text field, the Autocomplete widget gives suggested results. In this example, when you type at least two characters in the text field, related bird names will be displayed.

In this example, the datasource is a server-side script that returns JSON data, specified through a simple source option. In addition, the minLength option is set to 2 to avoid the query returning too many results, and the select event is used to display some feedback.

Remote caching

As you type characters in the text field, the Autocomplete widget gives suggested results. In this example, when you type at least two characters in the text field, related bird names will be displayed.

To improve performance, some local caching is added here; otherwise it is similar to the remote datasource example. Here, the cache only stores one query, and can be extended to cache multiple values, one value per entry.

          return;
        }
 
        $.getJSON( "search.php", request, function( data, status, xhr ) {
          cache[ term ] = data;

Scrollable results

When displaying a long list of options, you can simply set max-height on the autocomplete menu to prevent it from getting too long. Try typing "a" or "s" to get a scrollable long list of results.

XML data

This example demonstrates how to fetch some XML data, parse it using jQuery methods, and then provide it to autocomplete as a datasource.

This example can also be used as a reference for parsing remote XML datasources - parsing occurs on each source callback request.
