获取url后面的参数

var url='http://xxxxxxx.com/?code=021P6CY?name=123'
function obj(url,n){
var urlAry = url.split('?')[n].split('&');
  var urlObj = {};
  urlAry.map(item=> {
    item = item.split('=');
    urlObj[item[0]] = item[1]
  })
return urlObj}
function urlParse(url) {
var urlObj1= obj(url,1)
if(url.split('?').length<3){ return urlObj1;}//url后面有两个？
var urlObj2 =obj(url,2)
  return Object.assign(urlObj1, urlObj2)
}
urlParse(url)
