Js的Url中传递中文参数乱码问题

竟然经常遇到，但是每次都现找度娘，想想还是整理整理吧

重点：encodeURI编码，decodeURI解码

传参页面JavaScript代码：

var url = “bad.html”;
var userName ="王超";
window.open(encodeURI(url + “?userName=” + userName)); }

接收参数页面：bad.html:

var urlinfo = window.location.href;//获取url
var userName = urlinfo.split(“?”)[1].split(“=”)[1];//拆分url得到”=”后面的参数  
decodeURI(userName);
