Code to disable backspace

Hi.
I've a website 100% build on Ajax.

When the visitor click on Backspace, he is returned to the previous website he was in, and so goes away from the website.

Is there anyway to disable the backspace utility.

thanks.

This is standard browser functionality. It's not a good idea to change that behavior, as some people who browse primarily with keyboard will only be frustrated by it.

You may also trigger some security software as an intrusive behaviour.

I want to disable this as this is the standard browser functionality. When the user click backspace he is expecting to go to the previous page.

Ajax does NOT allow this.

so I want to catch the refeering page by any code, when the user click BACKSPACE he is back (by ajax too) to the page he came from.

I saw many posts in this forum but non worked with me.

Progress:

<script>
if (typeof window.event != 'undefined')
document.onkeydown = function()
{
if (event.srcElement.tagName.toUpperCase() != 'INPUT')
return (event.keyCode != 8);
}
else
document.onkeypress = function(e)
{
if (e.target.nodeName.toUpperCase() != 'INPUT')
return (e.keyCode != 8);

Final Reply: IT WORKED

<script>
function checkShortcut()
{
if(event.keyCode==8 || event.keyCode==13)
{
alert('Hi'); return false;
}
}
</script>
<body onkeydown="return checkShortcut()">

alert will be changed to ajaxpage("my refering page", "mytarget")
