/*
 * Get URL Parameters
 * http://www.netlobo.com/url_query_string_javascript.html
 * 
The way that the function is used is fairly simple. Let's say you have the following URL:

http://www.foo.com/index.html?bob=123&frank=321&tom=213#top

You want to get the value from the frank parameter so you call the javascript function as follows:

var frank_param = gup( 'frank' );

Now if you look at the frank_param variable it contains the number 321. The query string was parsed by the regular expression and the value of the frank parameter was retrieved. The function is smart in a couple of ways. For example, if you have an anchor in your URL like our example URL above does (#top) the gup() function knows to stop before the # character. Also, if a requested parameter doesn't exist in the query string then an empty string is returned instead of a null.

  var tmpURL = window.location.href;
  var results = regex.exec( tmpURL );

    return "";
