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;

}

调用方法：

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

alert(GetQueryString("参数名3"));

方法二

<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>

调用方法：

<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>
