AJAX
AJAX is the art of trading data with a web server, and changing parts of a web page, without reloading the whole page. AJAX is not a new programming language, but a new technique for creating better, faster, and more interactive web applications. With AJAX, a JavaScript can communicate directly with the server, with the XMLHttpRequest object. With this object, a JavaScript can trade data with a web server, without reloading the page. AJAX uses asynchronous data transfer (HTTP requests) between the browser and the web server, allowing web pages to request small bits of information from the server instead of whole pages. The AJAX technique makes Internet applications smaller, faster and more user-friendly.
Scott did a quick demo of AJAX for us at the last meeting. He showed us how to use Javascript to send data back and forth to the server using $_GET. He also has a demo that uses a $_POST that he did not show. Check that out on his [Scott Page]. Notice the links at the top of the page to see his code.
