js获取url传递参数，js获取url？号后面的参数window.location

 <Script language="javascript">
 function GetRequest() {
    var url = location.search; //获取url中"?"符后的字串
    var theRequest = new Object();
    if (url.indexOf("?") != -1) {
       var str = url.substr(1);
       strs = str.split("&");
       for(var i = 0; i < strs.length; i ++) {
          theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);
       }
    }
    return theRequest;
 }
 </script>
