方法一：正则

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]); returnnull;}

调用：

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]); //转化成对象        }    }    return theRequest;}
