jQuery UI 1.7: The User Interface Library for jQuery

By: jQuery Foundation, Dan Wellman

Overview of this book

Modern web application user interface design requires rapid development and proven results. jQuery UI, a trusted suite of official plug-ins for the jQuery JavaScript library, gives you a solid platform on which to build rich and engaging interfaces with maximum compatibility and stability, and minimum time and effort. jQuery UI has a series of ready-made, great-looking user interface widgets and a comprehensive set of core interaction helpers designed to be implemented in a consistent and developer-friendly way. With all this, the amount of code that you need to write personally to take a project from conception to completion is drastically reduced. Specially revised for version 1.7 of jQuery UI, this book has been written to maximize your experience with the library by breaking down each component and walking you through examples that progressively build upon your knowledge, taking you from beginner to advanced usage in a series of easy-to-follow steps. In this book, you'll learn how each component can be initialized in a basic default implementation and then see how easy it is to customize its appearance and configure its behavior to tailor it to the requirements of your application. You'll look at the configuration options and the methods exposed by each component's API to see how these can be used to bring out the best of the library. Events play a key role in any modern web application if it is to meet the expected minimum requirements of interactivity and responsiveness, and each chapter will show you the custom events fired by the component covered and how these events can be intercepted and acted upon.

The methods that we can use to control the selectables component from our code are similar to the methods found in other interaction helpers and follow the same pattern of usage. The only unique method exposed by the selectables component is listed below:




Manually refreshes the positions and sizes of all selectables. Should be used when autoRefresh is set to false.

Setting the autoRefresh property to false can yield performance gains when there are many selectables on the page, especially in IE. However, there will still be times when you will need to refresh the size and positions of the selectables, such as when this component is combined with the draggables component.

Let's take a look at the refresh method as it leads on perfectly from the last example. Add the following new <button> element directly after the selectables container:

<button id="refresh">Refresh</button>

We'll also need to link to the draggable source file for...
