Hi,

I have the following text string on a page XX_Test, the program I am working with needs this format but when it is displayed in the browser I want it to just display Test, I want the format to be changed when the page loads.

Bascially I want to strip the first 3 characters from this string.

Thanks

Check this:

<html>
<body onLoad="document.write(document.body.innerHTML.replace(/XX_/g,''))">

If you want to strip out anything before '_', then try this

<script type="text/javascript">
<!--
var str = "XX_Test";
document.write(str.substring(str.lastIndexOf('_') + 1));
// -->
</script>
