Description
This book endeavors to provide you with as much up-to-date information as possible regarding jQuery that can be reasonably included in a book consisting of roughly 200 pages. You need some familiarity with HTML Web pages and JavaScript, but no prior knowledge of jQuery is required.
Which Version of jQuery is for this Book?
The code samples in this book were initially written using jQuery 1.7.1. These code samples were upgraded to jQuery 2.0 beta, along with jQuery Migrate plugin (version 1.9.1) to ensure that the code samples do not contain any deprecated jQuery methods.
There are two benefits to this approach. First, you can use these HTML Web pages with jQuery 2.0 beta and be assured that they do not contain any deprecated jQuery code. In addition, if you need to use a version of jQuery prior to version 2.0 (perhaps due to an existing code base), these HTML Web pages work correctly without modification.
What About jQuery 2.0?
The current production version of jQuery is version 1.9, and jQuery 2.0 beta is also available. As this book goes to print, jQuery 2.0 will probably become available as well. The key point to remember is that jQuery 2.0 removes support for IE 6, IE 7, and IE 8, and also deprecates some jQuery methods that are available in earlier versions of jQuery. Fortunately, version 2.0 will be backward compliant with jQuery 1.9.
