AJAX tutorial

AJAX = Asynchronous JavaScript and XML.

AJAX is not a new programming language, but a new way of using existing standards.

The biggest advantage of AJAX is that it can exchange data with the server and update part of the web page content without reloading the entire page.

AJAX does not require any browser plug-ins, but requires the user to allow JavaScript to execute on the browser.
