Javascript parser code update

Max budget for this project is $10. The Issue: The code below can't process parameters with spaces, percent signs or () in it. Example URLS: [login to view URL] (awf_first)=first&name (awf_last)=last&email=email [login to view URL](awf_first)=first&name%20(awf_last)=last&email=email The code below needs to be able to parse the parameters above and fill a form with the values. Please don’t take away any functionality of the script, just add the ability to process the above URL examples. -Thanks Here is the code: <script type="text/javascript"> function _id(e){return [login to view URL](e)} var QueryString = function () { // This function is anonymous, is executed immediately and // the return value is assigned to QueryString! var query_string = {}; var query = [login to view URL](1); var vars = [login to view URL]("&"); for (var i=0;i<[login to view URL];i++) { var pair = vars[i].split("="); // If first entry with this name if (typeof query_string[pair[0]] === "undefined") { query_string[pair[0]] = decodeURIComponent(pair[1]); // If second entry with this name } else if (typeof query_string[pair[0]] === "string") { var arr = [ query_string[pair[0]],decodeURIComponent(pair[1]) ]; query_string[pair[0]] = arr; // If third or later entry with this name } else { query_string[pair[0]].push(decodeURIComponent(pair[1])); } } return query_string; }(); if([login to view URL]){ _id('name_f-0').value=[login to view URL]; _id('name_1-0').value=[login to view URL]; _id('email-0').value=[login to view URL]; _id('password').value=[login to view URL]; _id('contact').value=[login to view URL]; } // [login to view URL] // ex: [login to view URL] // [login to view URL] // [login to view URL] // [login to view URL] // [login to view URL] </script>
