1 What is Ajax?
1.1 Introduction
Asynchronous JavaScript and XML (Ajax) is a term for the process of
transferring data between a client script and the server. The advantage of
this is that it provides developers with a way to retrieve content from a
Web server without reposting the page the user is currently viewing to the
server. In concert with modern browsers??™ ability to dynamically change
displayed content through programming code (JavaScript) that accesses
the browser's DOM, Ajax lets developers update the HTML content
displayed in the browser without refreshing the page. Thus, Ajax
provides dynamic interaction between a client and a server. In other
words, Ajax can make browser-based applications more interactive, more
responsive, and more like traditional desktop applications.
