I still at the newbie stage as far as Javascript goes. How do you return a URL's Querystring using Javascript?

Not certain if there is a built in function for it, but you could just put the URL into a string object and parse it for:

Code:

<html> 
<head> 
<title>Select the products...</title> 
<meta name="Microsoft Theme" content="none"> 
<script language="JavaScript"> 
function SearchDemo()
{
   var r, re, ln;		//Declare variables.
   var qs = new String('');
   var s = new String(document.URL);
   re = "[?]";            	//Create regular expression pattern.
   r = s.search(re);            //Search the string.
   if (r != -1)
   {
       ln = s.length;
       qs = s.substring(r, ln);
   }

   return(qs);                   //Return the Boolean result.
}
function cmdDisplay_onclick()
{
   window.alert(SearchDemo());
}
</script> 
</head> 
<body> 
<input onclick="cmdDisplay_onclick()" type=button name=cmdDisplay value="ClickMe!">
</body> 
</html>

If you copy this into a HTML document in your wwwroot folder for IIS and call it with a querystring, when you click on the button it will pop up a dialog with just the querystring. (You can't specify querystrings when calling a file locally.. at least I couldn't)

That should get you close..

Use:

var myQuery;
myQuery = location.search;

This will return everthing from the "?" on. Then you can use the split() function to split the string on the "&"s, assuming that you have more than one value.
