Hi this is your solution the internet Explorer itself provides the confirm() functionality where you can find the two buttons ok and cancel and the corresponding code on the basis of input is shown below with the example

You should call this function on the event onunload

like this

Code:

///////////////////
<body onunload="windowClose();"
////////////////////////////////////////////////


<script type="text/javascript">
function windowClose()
{
var r=confirm("Window will be closed do U want to Proceed");
if (r==true)
  {
            top.close();  
  }
else
  {
         (Do whatever you like);
  }
}

Hi
I think you have posted your question in the wrong forum BUT anyway , here is your answer:

Code:

<head>
<script type="text/javascript">
	var myclose = false;
	function ConfirmClose()
	{
		if (event.clientY < 0)
		{
			event.returnValue = 'Are you sure you want to close this window!';
			setTimeout('myclose=false',100);
			myclose=true;
		}
	}
</script>
</head>
<body onbeforeunload="ConfirmClose()">
</body>

Please note that this code only works for IE.

Not just Internet Explorer - every browser (or at least every major one) has a confirm() method.

Instead of onunload, you'd have to use onbeforeunload though because once it gets to the unload event, you can't prevent it. Note that onbeforeunload is not supported in all browsers.

One final point to bear in mind: it is rarely a good idea to have a confirmation when the user clearly wants to leave the page/close the browser.
