VBScript to Javascript

I have been told that any VBScript can be transformed into Javascript. I have this page in VBScript that needs to be converted…

[code]
<%@ Language=VBScript %>
<html>
<head>
<title>Search</title>

<script>
function viewHelp(sourcefile, w, h) {
winPop = window.open(sourcefile,"Help","width="+w+",height="+h+",scrollbars=yes, screenX=75,screenY=75,left=75,top=75");
}
</script>
</head>

<body bgcolor="#ffffff">
<div align="center">
<table>
<tr><td class="tdWhite"><a href="javascript:viewHelp('instructions.htm', 425, 400);">Instructions</a></td></tr>
</table>
<table border="0" cellpadding="0" cellspacing="0">

Thanks pillbug, that will help me learn in the future, but I need that translated asap...

Ok, the truth of the matter is, this script works fine on an ASP enabled server, but I was tasked to create a DHTML version that would not need a server to run. I technically don't know if this is possible but I think it would be…

PurplePerls

Now that was what I assumed.
And the answer is: it would be possible, but only on that one machine where the server is running AND only when the page is invoked locally on that machine, not trough a web server.
The reason is that it is not possible to examine anything on server side what is not on client side.
Therefore you can not run a full text search on client side which does a lookup of server side repository.
Additionally you can not instantiate an ActiveX module from a web server page to lookup client side objects.

Sorry for the bad news.

I would agree - server-side code (VBScript) isn't interchangable with client-side code (JavaScript). The VBScript runs code on the webserver (which has to allow it), and can't access the client.

Client-side code runs on your local browser and can't access the server. You need to be able to run code on ther server in order to use your ActiveX control.

Ok, now we are getting somewhere.

In the DHTML version there would be no server. Everything would be contained on a CD or in an EXE.

If this code cannot be converted to be able to do this please tell me how I can close/delete this topic...
