Creating a contacts application with AJAX part 2

In the first part of this tutorial, we looked at some of the theory behind AJAX, a new approach to building Web applications. AJAX uses XML, XSLT, XHTML and CSS, JavaScript and the DOM and the XMLHttpRequest object to create applications. The key advantage is that data loads asynchronously, so there’s no need to reload the page each time the user requests new data. This creates a more responsive application and an improved user experience.

In the second part of the tutorial, we’ll build a simple address book application. We’ll start by displaying a hyperlinked list of contacts. When we click each contact’s link, we’ll show the details of the contact below. We won’t need to reload the page each time we click a link, speeding up the browsing process
