JS获取URL参数

<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>

然后我们通过调用此函数获取对应参数值：

<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>

以此获取url串中所带的同名参数

二、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"));
