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 deal with drag and droppables

Dragging and dropping, as behaviors, go hand-in-hand with each other. Where one is found, the other is invariably close by. Dragging an element around a web page is all very well, but if there's nowhere for that element to be dragged to, then the whole exercise is usually pointless.

You can use the draggable class independently from the droppable class as pure dragging for the sake of dragging can have its uses, such as with the dialog component. However, you can't use the droppable class without the draggable. You don't need to make use of any of draggable's methods of course, but using droppables without having anything to drop onto them is of no value whatsoever.

Like with the widgets, it is possible however to combine some of the interaction helpers, draggables and droppables go together obviously. But draggables can also be used with sortables, as we'll see in Chapter 12.
