We cover areas such as: • Handling keyboard and mouse events • Form validation techniques • Applying animation effects • Manipulating the DOM • Advanced table handling • Working with JSON and XML data For each problem, we carefully define what the issue is first, and then pro- vide the code solution along with any required HTML and CSS to get the exam- ple working. Where there are numerous permutations to the problem, we’ll run through a set of solutions to keep you fully armed for all eventualities. The code is then carefully explained so that you understand the core details of the solution and can apply them to your own code any time you come across a similar issue. Along with using the book as a reference to dip into for answers, you can also use it for increasing your knowledge of jQuery. By reading through the solutions and trying out the fully illustrated and explained sample code, you will gain a bet- ter understanding of the inner workings of the jQuery framework and how it can be used to make your websites more dynamic and sticky.
