Wow, all this code for a simple popup?
Save this:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>Page</title>
<script type="text/javascript">
<!--
function popup(msg)
{
alert(msg);
}
window.onLoad = popup('Blah, Javascript ... Ajax is the bomb.');
//-->
</script>
</head>
<body>
Hello.
</body>
</html>
Instead of the alert, use whatever you like as HTML code.
