JavaScript parse query string values

A quick post on how to use JavaScript to retrieve a query string value.

   // Function to parse the querystring
   getQueryString= function(sVar) {
        return unescape( RegExp("^(?:.*[&\\?]" + escape(sVar).replace(/[\.\+\*]/g, "\\$&") + "(?:\\=([^&]*))?)?.*$", "i"), "$1"));

   // Get the value
   var queryParam = getQueryString("your key");
