parse string in URL

I’m horrible at javascript, I need help.

I’m trying to parse a string from a URL and pass it as a parameter to another function. If that parameter meets certain conditions, I want hidden fields in my form to “unhide”.

Here’s why I need this:
I am giving 3 usersr a specified url i.e. ([url]http://DOMAINNAME.com?usr=uk[/url] or [url]http://DOMAINNAME.com?usr=france[/url]) and based on that url, we’ll parse the name and pass it as a parameter to a function. (i think i expressed that right??) Then we will display the proper shipping address depending on the parameter passed. My only problem now is, i’m horrible at writing regular expressions and programming in general. Do you or anyone else out there know of any good url parseing functions? I’ve been doing mostly project management throughout my career and never really got a chance to become fluent in javascript or programming for that matter. I’ll be doing my research in the mean time. Thanks again for all your help, much appreciated.
