Prevent user to move back page on pressing of back space key through java script.

I can try this but It should't work on Firefox browser but work on Google Crome browser.
I can use this code.

<script language="javascript" type="text/javascript">

function cancelBack()
{
if ((event.keyCode == 8 || (event.keyCode == 37 && event.altKey) || (event.keyCode == 39 && event.altKey))
&&
(event.srcElement.form == null || event.srcElement.isTextEdit == false)) {

event.cancelBubble = true;
event.returnValue = false;
}
}
</script>

and call this function like this.

<body onkeydown="return cancelBack();">
</body>

Please any one help me to solve this problem.

thanks in advance.

You shouldn't do it. Overriding the behaviour the user expects is not good user experience. if you have to, try using event.preventDefault();

You could return false as additional measure. The code below supports IE < 9. This assumes all your conditions in if clause are correct, I just copied them.

JavaScript

var event = e || window.event;
if ((event.keyCode == 8 || (event.keyCode == 37 && event.altKey) || (event.keyCode == 39 && event.altKey))
&&
(event.srcElement.form == null || event.srcElement.isTextEdit == false)) {

event.stopPropagation ? event.stopPropagation() : (event.cancelBubble=true);
}

If this helps please take time to accept the solution. Thank you.
