Code:
<html>
<head>
<script type="text/javascript">
onload = function(){
document.getElementById('btn1').onclick = function(){
if (window === window)
alert('window === window')
else
alert('window !== window');
if (window.event === window.event)
alert('window.event === window.event')
else
alert('window.event !== window.event' );
}
}
</script>
</head>
<body>
<button id="btn1" >click</button>
</body>
</html>
Result:
IE(i have tested IE6 - IE8) says:
window === window
window.event !== window.event
All other browsers say:
window === window
window.event === window.event
What's the reason for IE's response? Thanks.
