AJAX Beginners' tutorial

AJAX is a mix of technologies which allows you to get extra data from the Web server even after the page has finished loading. JavaScript is used to send requests to PHP pages which get the data from MySQL and send it back to the JavaScript which then displays the data on the page or uses it in other ways. Google's autocomplete search box may be the best known example.

AJAX is really easy. There is almost nothing to learn as it is just a mix of what you already know. It can use other technologies but here it is a mix of XHTML, JavaScript, PHP and MySQL. If you haven't done the beginners' tutorials on all of those do them now!
