通过js获取Url的参数值

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"));

		

<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>
