[Peter-Success]

           var str = window.location.search.substr(1),
           num = 0,
           arr1 = [],
           arr2=str.split("&");
           for(var i=0;i < arr2.length;i++){
               var num=arr2[i].indexOf("="),
                     obj = {};
               if(num>0){
                   obj.key = arr2[i].substr(0,num);
                   obj.value = arr2[i].substr(num+1);
                   arr1.push(obj)
                };
            };
