Ajax: A New Approach to Web Applications

The Internet as we know it today has undergone tremendous change. Beginning with simple textual browsers that allowed scientists to exchange research, the Internet is now a hub for commerce and information. Over that time, we’ve seen a number of new technologies and approaches—from the earliest graphical browsers to podcasts. Today, the Internet has become the leading platform for numerous applications.

Ajax (Asynchronous JavaScript and XML) isn’t a technology. It is really several technologies, each flourishing in its own right, coming together in powerful new ways. Ajax incorporates:

• Standards-based presentation using XHTML and CSS; • Dynamic display and interaction using the Document Object Model; • Data interchange and manipulation using XML and XSLT; • Asynchronous data retrieval using XMLHttpRequest; • and JavaScript binding everything together.

That is because Ajax enables your Web applications to work behind the scenes, getting data as they need it, and displaying that data as you want. And as more and more people get fast Internet connections, working behind the scenes to access data is going to become all the rage. Soon, it will be impossible to distinguish dedicated desktop software from software that is actually on the Internet, far from the user’s machine. To help you understand how Ajax works, the following sections look at Ajax from a user’s and a programmer’s perspective.
