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.

Downloading the library

To obtain a copy of the library, we should visit the download builder at, which gives us a range of different options for building a download package that is tailored for our particular implementational requirements. The following screenshot shows the download builder:

We can either download the complete current release of the library, or a complete package of the legacy 1.6 version, or we can select the components that we want and download a custom package.


This book is specifically tailored towards version 1.7 of jQuery UI (at the time of writing the current stable release is 1.7.2) and is not compatible with legacy versions of the library. jQuery UI 1.7 requires jQuery 1.3.

The page is laid out in a really friendly and easy-to-use way. It lists all of the different components in their respective groupings (core, interaction helpers, and widgets) and allows us to choose from one of 25 different predesigned themes along with providing information about the package (including both its compressed and uncompressed size).

We'll look at the different files found within the library in just a moment, but for now we should download the complete library. It will contain everything we need, including the JavaScript and CSS files, as well as any images from the current theme that different components rely on. It even contains the latest version of jQuery itself, so we don't need to worry about downloading this separately.

For now, just use the Current (stable) link at the top of the page. This will give us the default theme that is called smoothness. We'll look at downloading and using other themes in the next chapter.


Hosted Files

In reality, we don't even need to download the library in order to implement it in a production web application. Both jQuery and jQuery UI are hosted on Google's content delivery network (CDN), so we can include <script> elements that link to these files instead of using local versions. Only the complete library (not individual components) is available, although there are a range of different releases.

On a live site that receives a lot of international traffic, using a CDN will help ensure that the library files are downloaded to a visitor's computer from a server that is geographically close to them. This helps in making the response quicker for them and saving our own bandwidth. This is not recommended for local development however.
