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.

Chapter 11. Selecting

The selectables component allows you to define a series of elements that can be 'chosen' by dragging a selection square around them or by clicking them, as if they were files on the desktop. In this way, elements on the page can be treated as file-like objects, allowing either single or groups of them to be selected.

A selection square has been a standard part of modern operating systems for a long time. For example, if you wanted to select some of the icons on your desktop, you could hold the mouse button down on a blank part of the desktop and drag a square around the icons you wanted to select.

The selectables interaction helper adds this same functionality to our web pages, which allows us to build more user-friendly interfaces without needing to use external environments like Flash or Silverlight. This is yet another example of how the Web is increasingly becoming less distinct from the desktop as an application platform.
