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;    }

这样调用：

alert(GetQueryString("参数名1"));alert(GetQueryString("参数名2"));alert(GetQueryString("参数名3"));

方法二：

<span style="font-size: 16px;"><Script language="javascript">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;}</Script></span>

这样调用：

<Script language="javascript">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'];</Script>
