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.

Dialog's event model


The dialog widget gives us a wide range of callback options that we can use to execute arbitrary code at different points in any dialog interaction. The following table lists the option available to us:

Option

Fired when

beforeclose

The dialog is about to be closed.

close

The dialog is closed.

drag

The dialog is being dragged.

dragStart

The dialog starts being dragged.

dragStop

The dialog stops being dragged.

focus

The dialog receives focus.

open

The dialog is opened.

resize

The dialog is being resized.

resizeStart

The dialog starts to be resized.

resizeStop

The dialog stops being resized.

Some of these callbacks are only available in certain situations, such as the drag and resize callbacks, which will only be available when the draggable and resizable components are included. We won't be looking at these callback options in this chapter as they'll be covered in detail later in the book.

Other callbacks such as the beforeClose, open, close, and focus...
