jsp分頁顯示完整實例
這篇文章主要介紹了jsp分頁顯示完整實例,以文章管理頁面為例詳細分析了jsp的分頁顯示實現技巧,具有一定參考借鑒價值,需要的朋友可以參考下
本文實例講述了jsp分頁顯示的實現方法。分享給大家供大家參考。
具體實現方法如下：
代碼如下: <%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %><%@include file ="../inc/ChkPwd.jsp"%>
<%@include file="../DB.jsp"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
