hi ...

while the standard HTTP request makes a 'synchronous' call and must wait for the response and makes a page-reload (you always get a new html-page to display) a XMLHttpRequest may be used sync (not typical) and async (the better way) without a page-reload. you may ask for the response with javascript and the response is usually xml- or json-data that you may process with js and update parts of your page through the use of dom-methods that manipulate your document ... so you don't need an entire page-reload because all of that is running in the 'background' ...

kind regards

Changed thread title to better describe the problem (did you know that threads whose titles that do not follow the Posting Guidelines actually get FEWER responses?).

Hi,
We all know, in Ajax, Javascript can get information from the server without
having to load a new page!
How does it works?
can any one explain in clear picture??

Look.
AJAX works behind the screen.
This is simply a HTTP request or HTTPS or simply a request as made generally and we can see how the page reloads.
But AJAX works slight Differently.
When a normal Request made then the Target Page is rendered with specific MIME Type.
It may be HTML,XHTMLor XML.
But it just returns back the output but on working in the behind means user's unknown.
Then simply parse that output using standard API provided bu JavaScript and update the target page that's why the page seems not to be reloaded.
I think you goy my point.
