[chowdhury]

Dear Sir,
I am trying to catch the close button event(X) at internet explorer 8.
i trying with follwoing code.but in that case i can detect tab button while it's close(X) is clicked.

function closeIt(){
    
if( !event) { event = window.event ; } 

 if (event.clientY < 0)
 			{
         		 //event.returnValue = 'Are you sure you want to Quit?'
		 }
   }

<body   onBeforeUnload="closeIt()">
</body>

if its just for an alert then you might try:

window.onbeforeunload = function() {
    alert('foo')
}
