JS如何获取URL

一、
var url=document.location;
url ="www.abc.com/sports/def.aspx";
var r =/\/(\w+)\.aspx/;
alert(url.match(r)[1]);
alert(r.exec(url)[1]);

二、

 var url = document.location
url = " http://localhost:8080/Customer/index?token=ghfghfghfghfgh&mediaUserID=120122&redirect_url=www.wwwghgh.com";
 var[] parm = url.Split('&');
    var token = parm[0].Split('=')[1];
    var userId = parm[1].Split('=')[1];
    var Redirect = parm[2].Split('=')[1];
