JS截取url中的信息

var url=location.search;

var ename;

var Request = new Object();

if(url.indexOf("?")!=-1)

{

       var str = url.substr(1);

      strs= str.split("&");

       for(var i=0;i

     {

        Request[strs[i].split("=")[0]]=(strs[i].split("=")[1]);

      }

}

ename = Request["ename"];  

例如：url是：http://www.medivh.com?ename=right

那么获取的ename就为：right.
