Chapter 15. Introducing Ajax
There was something new (actually not so new, as we'll see) powering these sites, and it is called Ajax. You can use Ajax techniques to make your sites more responsive and attractive, which makes your site's users happier in the process. Best of all, you don't have to learn a completely new technology, because Ajax is made from building blocks that you already know (and that we've covered earlier in this book).
In this chapter, you'll learn how to request information from the server in the background and turn it into a form your Ajax application can use; automatically refresh the information from the server; build a cool previewing effect for objects on your page; and build an Ajax application that auto-completes form fields, just like a desktop application. Let's get to it.
