AJAX = Asynchronous JavaScript and XML.
AJAX is not a new programming language, but a new way to use existing standards.
AJAX is the art of exchanging data with a server, and updating parts of a web page - without reloading the whole page.
Example script :
Create two files :
1) main file
2) load file
create main.php this is main file.
The second file is load.php this file load every 5 second.<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js"> </script> <script> setInterval( function() { $('#content').fadeOut('slow').load('load.php').fadeIn("slow");}, 3000); </script> <title>Auto Load Page Div using Jquery - similar to twitter Live Search</title> </head> <body> <div id="content" style="background-color:#ffffcc;font-size:24px;font-weight:bold;width:600px;margin:auto 10px;">Please wait.</div> <a href="#" target="_blank">Home</a> </body> <html>
echo'This content is loaded via ajax every 5 seconds ..';
