怎么能在客户端操作服务端对象呢？改成这样的
<%@ page language="java" contentType="text/html;charset=gb2312"%>
<form method="post" name="form3" action="action.asp">   /**提交到action*/
   <tr>
      <td>
       <input name="ddfind" type="radio" value="订单查询" checked="checked" id="2" />订单查询&nbsp;&nbsp;&nbsp;
       <input name="ddfind" type="radio" value="合同查询" id="3"/>合同查询
       </td>
    </tr>
</form>action.jsp
<%
String nowValue=request.getParameter("ddfind"); //取得ddfind的值
String tempFile=nowValue.equals("订单查询")?"zy_info_10.jsp":"contract_search.jsp";
response.sendRedirect tempFile;
%>
