Part 4. Ajax by example

The five complete Ajax projects in this section demonstrate the full process of building compelling interactive elements for your web applications. In each case, we’ve developed a straightforward example, step by step, so you can see how it works. We’ve then refactored the code so that the example can be dropped into your own projects easily. The examples cover the full spectrum of what Ajax can do, from enhancing form elements to developing complete portal solutions, communicating to both your own server-side processes and to standard Internet services. We’ve deliberately chosen a mixture of popular server-side programming languages in which to implement the server-side code, so you’ll find a medley of PHP, Java, VB.Net and C# in this section. The downloadable code available from the website will contain multiple implementations of the sever-side back-end for each chapter. Have fun!
