Overview of this book

jQuery UI is the quintessential framework for creating professional user interfaces. While jQuery core lays the foundation for interaction with the DOM and handling events, jQuery UI fills in the user interaction gap. This book will give you a huge productivity boost out of the box with jQuery UI, and help you understand the framework, inside and out."jQuery UI Cookbook" provides you with practical recipes featuring in-depth coverage of every widget in the framework, including how to address limitations that impact your everyday development activities with these widgets. You'll get a better idea of the big picture – how the framework is composed, how the widgets relate to one another, and how to build on those patterns.Be it a minor tweak on the visual design of a progress bar or a fundamental change in a widget to meet your needs, "jQuery UI Cookbook" covers scenarios both big and small. You can show reminders as tooltips, apply a variety of effects to the menu widget, and start interactions between the dialog widget and API data using deferred objects. These and many more interesting tasks are covered in this book, which can be done with smooth learning and great understanding. You will see how button widgets can fill the width of their containing element, making the layout more consistent. Tabs can be sorted and moved between widgets. You will learn how to do all these things within the context of the big picture, by finding out why the components work the way they do, making you well-versed in jQuery UI.

Using multiple data sources

Sometimes, an autocomplete widget doesn't map directly to one data source. Take video for instance. Imagine the user needs to pick a video, but the two data sources are DVD and Blu-ray. If we were to use autocomplete to select a video, we would need a way to assign multiple data sources. Furthermore, the mechanism would need to be extensible enough to support adding more data sources, especially since there is a new video format born every other year.

How to do it...

The default implementation of the autocomplete widget is expecting a single data source – an array or an API endpoint string. We'll give the widget a new sources option to allow for this behavior. This is how we'll extend autocomplete and create an instance of the widget that has two video data sources – one for DVDs, and one for Blu-ray discs.

( function( $, undefined ) {

$.widget( "ab.autocomplete", $.ui.autocomplete, {

    options: { 
        sources: []    

    _create: function() {
