Disable Backspace

[k0r54]

Hi,

Just a quicky how can i disable the backspace. I have found code for the enter key but dont understand it. So any help will be great thanks

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

function checkCR(evt) {

var evt = (evt) ? evt : ((event) ? event : null);

var node = (evt.target) ? evt.target : ((evt.srcElement) ? evt.srcElement : null);

if ((evt.keyCode == 13) && (node.type=="text")) {return false;}

}

document.onkeypress = checkCR;

</script>

Tnx Adz

The question that needs to be answered first is why would you want to do that?

[k0r54]

The reason why is because, at work our agents use webscript and on the web script there is an ocx, but when you press back space it goes back a page and i cant do anything about it.

So the best way is to disable backspace on that page.

Thanks Adam

Get ASCII chart, lookup code for "Backspace" and replace 13 with it.

Then, I guess, the browser catches the event before it is passed to the page, which means you are out of luck.

Maybe try listening for it onkeydown instead of onkeypress. You might be able to catch the event that way.

Try This:

<script type="text/javascript">

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);
}

</script>
