js method to get parameters from page

This article mainly introduces the parameters transmitted from the page through window.location.search. It is OK after testing

 function GetQueryString(name) { var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)","i"); var r = window.location.search.substr(1).match(reg); if (r!=null) return (r[2]); return null; } var sname = GetQueryString("name"); if(sname!=null) { var sname_ = decodeURIComponent(sname); alert(sname_); }

test

abcd.html?name=xyz

xyz should pop up
