       <s:iterator value="scorelist">

            <td><s:property value="id.{number}.toString().substring(1,id.{number}.toString().length()-1)"/></td> 
            <td><s:property value="id.{name}.toString().substring(1,id.{name}.toString().length()-1)"/></td>

            <td><s:property value="id.{course}.toString().substring(1,id.{course}.toString().length()-1)"/></td>
            <td><br><s:property value="id.{score}.toString().substring(1,id.{score}.toString().length()-1)"/></td>
        </tr>
            </s:iterator>       
    </table>        
  </body>
</html>

2.action中的提交数据

 HttpServletResponse response = ServletActionContext.getResponse();
		 response.setContentType("text/html;charset=utf-8");
		 PrintWriter out = response.getWriter();
		 out.print(scorelist);//传到前台的值
		 out.flush();
		 out.close();

3.效果截图

4.用js实现感觉将list显示出来比较复杂,所以专用jquery。
