javascript Working with QueryString

I've write a beter function for getting the values from the Querystring. I'm sure, there is a better code and better way. I show you the code (blospot has some problems with the code formating):

/*
function getQueryString(){
 var search = location.search.substring(1);
 var result = {};
 var elements = search.split("&");
 var element = '';
 var key = '';
 var value = '';

 for(var i=0; i<elements.<length>; i ++){
  element = elements[i].split('=');
  key = decodeURIComponent(element[0]);
  value = decodeURIComponent(element[1]);
  result[key] = value;
 }
 return result;
