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= %>
< file =../inc/chkpwd.jsp%>
< file=../db.jsp%>
<!doctype html public -//w3c//dtd xhtml 1.0 transitional//en >
<html xmlns=>
<head>
<meta name=robots content=noindex,nofollow />
<meta http-equiv=content-type content=text/html; charset=gb2312 />
<title>文章管理</title>
<link href=style.css rel=stylesheet type=text/css />
</head>

string sqldel=delete from hl_news where id= + id;
int shan=stmt_channeldel.executeupdate(sqldel);
if (shan>0)
