　　<a href="index.jsp?action=new">新品上架</a>
<a href="index.jsp?action=tejia">特价商品</a>
我的意思是想实现当进入index时首先显示new.jsp，当点特价商品时就显示特价商品tejia.jsp，也就是想实现象框加的功能　，还想问一下就是
我按上面那样写怎么不点任何连接right.jsp也不能显示．没有包含在if语句里面啊．

是你搞错了吧，应该显示的！

<%
String select=request.getParameter("action");
%>
<table>
<tr>
<td width="65%" valign="top" bgcolor="#FFFFFF">
<%@ include file="flash.jsp"%>
<%if (select!=null&&select.equals("new")){%>
<%@ include file="new.jsp"%>
<%}else if (select!=null&&select.equals("tejia")){%><%@ include file="tejia.jsp"%><%}%>
</td>
<td width="17%" valign="top" bgcolor="#FFFFFF"><%@ include file="right.jsp"%></td>
</tr>
</table>
