网络 1970-01-01JSP编程5684
这篇文章主要介绍了jsp分页显示完整实例,以文章管理页面为例详细分析了jsp的分页显示实现技巧,具有一定参考借鉴价值,需要的朋友可以参考下

本文实例讲述了jsp分页显示的实现方法。分享给大家供大家参考。

具体实现方法如下：

复制代码 代码如下:
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>
<%@include file ="../inc/ChkPwd.jsp"%>
<%@include file="../DB.jsp"%>

 int shan=stmt_ChannelDEL.executeUpdate(Sqldel);
 if (shan>0)
 {
  out.print("<script type="text/javascript"> alert("已成功删除！"); window.location.href='Hanye_Manages.jsp?BigClassName="+bbb+"'; </script>");
 }
 stmt_ChannelDEL.close();
 return ;
}
 Statement stmtA=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_READ_ONLY);
 String SqlA="Select * from hl_smallclass WHERE bigname='行业新闻' order by id asc";
 ResultSet RsA=stmtA.executeQuery(SqlA);
