如何实现 当点下一页到最后一页的时候，在点下一页就跳转到第一页？？？？

<%if rs.pagecount > 0 then%>
               <td width="28%" align="left">当前第<%=intpage%>页 共<%=rs.PageCount%>页</td>
               <%else%>
               <td width="8%" align="left">当前页0/0</td>
               <%end if%>
               <td width="64%" align="right"> <a href="index_DQ.asp?page=1">首页</a>  
               <%if pre then%>
               <a href="index_DQ.asp?page=<%=intpage -1%>">上页</a>  
      <%end if%>
               <%if last then%>
               <a href="index_DQ.asp?page=<%=intpage +1%>">下页</a>   
               <%end if%>
      <a href="index_DQ.asp?page=<%=rs.PageCount%>">尾页</a>  转到第  
               <select name="sel_page" onchange="javascript:location=this.options[this.selectedIndex].value;">
               <%
               for i = 1 to rs.PageCount
               if i = intpage then%>
               <option value="index_DQ.asp?page=<%=i%>" selected><%=i%></option>
               <%else%>
               <option value="index_DQ.asp?page=<%=i%>"><%=i%></option>
               <%
                 end if
                 next
                 %>
               </select>页</font></td>
