JS how to get the parameters of the address bar

Methods to get parameters (using regular expressions)

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;}

　　

How to use

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

Get Namevar name = Geturlparam ("name");
Console.log ("name=" +name);//name=lxy
