Hi
When i close the browser window using the
'X' in the top right hand side of the browser window, i want to execute a method of javaScript.

I believe the javascript event you are looking for is onClose();

Ramana

javascript:
window.onunload = function(){ alert(); }

Use can use onload attribute in the body tag
to specify the method to be executed.
But remember the event onunload gets fired when the refresh/reload button of the browser get clicked.

The event is onunload and not unload as written
by me in my previous post.

Ramana,
I hate to say this but, your name does not comply with the Javaranch naming guidelines which can be found at http://www.javaranch.com/name.jsp
please register again with a valid name.

The way to detect if a wiindow is closed is with an unload function and some extra checking of the event object
function onClose()
{
if ((window.event.clientX<0) && (window.event.clientY<0))
alert("you closed me");
}
...
<body onunload="onClose()">
Have Fun.

PLEASE LOOK AT THE DATE

The question may have been old - but the most satisfactory answer ( in my case anyway) was that provided by Dave Appleton.
Surely adding new and correct information can't be a bad thing.

The answer is not a cross browser supported answer plus I can give that answer to anyone that asks. Plus since no one seems to know what a search button is lately I doubt they would have found the answer.
I have people come in here before and answer 15 questions that were posted way in the past, I do not want that to be a habit of new posters.
If you used the submit button, I would be impressed.
