I recently finished reading Dan Wellman‘s book, jQuery UI 1.7 – The User Interface Library for jQuery. But with the imminent realease of version 1.8 of the popular interface library, is this book still relevant? In my opinion,  it is.

This book is recommended for beginner to intermediate users of jQuery UI, and it hits the mark perfectly for its intended audience. There’s a chapter for each of the high and low level widgets, as well as the CSS and effects frameworks. Each chapter is structured to follow a logical pattern, and Dan’s clear writing style means that the code and text is easy to follow.

Each chapter starts with a basic example, and gradually adds more and more options to show the flexibility and power of the framework. The text is supported by numerous code samples, which can be downloaded from Packt Publishing‘s support site. Finally, each chapter ends with an imaginative, more advanced use of the library. One chapter showcases jQuery UI’s drag and drop functionality with a game, for example. These examples really bring the code to life, and inspire you to open your favourite text editor and start coding!

The most obvious omission from this book (in fact, the only one worth mentioning, really) is the lack of a section on writing your own plugins for jQuery UI. Dan obviously feels the same way, because he’s written a tutorial on the subject here, and something like this is promised for the next update of the book. If this more advanced topic is something that interests you, you might want to wait for the next version of the book.

Alternatively, if your knowledge of jQuery UI is at the other end of the spectrum, there’s no reason at all not to go ahead and buy the current version. The book focuses on the common features of each widget (for example the destroy, enable, and disable methods) so that you can easily adapt to the new components as they appear.

If you’re somewhere between the two camps, as I was, then this book will consolidate your knowledge and give you lots of inspiration to use the parts of the library you might not have touched on yet. And that, for me, was worth the cover price alone.
