现在出现一个奇怪的问题，请大家帮帮忙！
配置了伪静态
<RewriterRule>
        <LookFor>~/SevenNews/(.[0-9]*)\.html</LookFor>
        <SendTo>~/SevenNews.aspx?type=$1</SendTo>
      </RewriterRule>
用JS却获取不到URL的type参数，但是不用伪静态转发直接用SevenNews.aspx?type=1就可以获取到URL参数。
JS用的是
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;

}

请教高手！谢谢！非常感谢！
