jsp分页显示完整实例

  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);
