URL参数解析

1、

function analyticParameter(){    var URL = document.location.toString();    if(URL.lastIndexOf("?")!=-1){        var QueryString= URL.substring(URL.lastIndexOf("?")+1,URL.length);        var tmpArr1=QueryString.split(",");        var tmpArrs=tmpArr1[0].split("=");        if(tmpArrs[0]=="jzdm"){            jzStationName =parseInt(decodeURI(tmpArrs[1]));        }        else{            jzStationName = null;        }    }    else{        jzStationName = null;    }}

2、

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

var username = decodeURI(GetQueryString("username"));
