js如何获取地址栏的参数

function GetUrlParam(name){
  var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");
  var r = window.location.search.substr(1).match(reg);
  if(r!=null)return unescape(r[2]); return null;
}

String url ="localhost:8080/Demo/index.html?id=123&name=lxy";

//获取id

var id = GetUrlParam("id");
console.log("id="+id);//id=123

//获取name

var name = GetUrlParam("name");
console.log("name="+name);//name=lxy
