js获取url参数值

方法一：正则分析法

function getQueryString(name) {    var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i");    var r = window.location.search.substr(1).match(reg);    if (r != null) return unescape(r[2]); return null;    }alert(GetQueryString("参数名1"));alert(GetQueryString("参数名2"));alert(GetQueryString("参数名3"));

方法二：

function GetRequest() {    var url = location.search; //获取url中"?"符后的字串    var theRequest = new Object();    if (url.indexOf("?") != -1) {       var str = url.substr(1);       strs = str.split("&");       for(var i = 0; i < strs.length; i ++) {          theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);       }    }    return theRequest; } var Request = new Object();Request = GetRequest();var 参数1,参数2,参数3,参数N;参数1 = Request['参数1'];参数2 = Request['参数2'];参数3 = Request['参数3'];参数N = Request['参数N'];
