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 5. The Dialog

Traditionally, the way to display a brief message or ask a visitor a question would've been to use one of JavaScript's native dialog boxes (such as alert or confirm) or to open a new web page with a predefined size, styled to look like a dialog box.

Unfortunately, as I'm sure you're aware, neither of these methods is particularly flexible to us as developers, or particularly engaging for our visitors. For each problem they solve, several new problems are usually introduced.

The dialog widget lets us display a message, supplemental content (such as images or text), or even interactive content (like forms). It's also easy to add buttons, such as simple ok and cancel buttons to the dialog and define callback functions for them in order to react to their being clicked.

The following screenshot shows a dialog widget and the different elements that it is made of:
