Some people here may know that I've been trying to find a js reloader.
With IE you can change the src of script[0], but with NS you needed an empty script so you can call a new js source to it.....

just done some experimenting and came up with this.......
Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" 
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>untitled</title>
</head>
<script type="text/javascript" language="javascript">
function changeScript(newScript) {
oldScript=document.getElementsByTagName("script" )[1]
var newEl = document.createElement('script');
newEl.setAttribute('type', 'text/javascript');
newEl.setAttribute('src', newScript);
oldScript.parentNode.replaceChild(newEl,oldScript);
changeScript.el = newEl;
return true;
}
</script>
<body>
<script type="text/javascript" src="js1.js"></script> 
<button onclick="changeScript('js2.js')">New JS</button>
<button onclick="changeScript('js1.js')">Old JS</button>
</body>
</html>
give it a try, set up 2 external js files, js1.js and js2.js, with a different alert in each.
works in NS and IE ( don't know about firebird, but not in opera )

Is there something I can add to this script to stop it caching it's js, like a delete???
