推荐答案
<body onunload.</code><br />
check out which one suits you..
<script type="text/javascript" language="javascript">
window.onbeforeunload = function(event)
{
var msg = 'Are you sure you want to leave?';
if (((window.event.clientX || event.clientX) < 0) || ((window.event.clientY || event.clientY)<0)) // close button
{
event=window.event;
event.returnValue = msg;
return msg;
}
if ((window.event.clientX < 0) || (window.event.clientY<0)) // close button
{
event=window.event;
event.returnValue = msg;
return msg;
}
else if (window.event.altKey == true || window.event.ctrlKey == true) // ALT + F4
{
event=window.event;
event.returnValue = msg;
return msg;
}
else // for all other unload events
{
}
}
</script>
