I have a url with parameters like the following:

http://test.com/mycode.html?xyz&myvar=value2

I need to endup with the following available to JS

base_file = mycode.html
parameter1 = xyz
parameter2 = value2 or myvar = value 2

What is the easiest way to parse the query string out of the url? When I use self.location I get everything.

Thanks.
