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<strs.length;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.
