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：<%@ 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" "https://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

}
if (op.equals("del") && ID!=null){
String bbb = new String(request.getParameter("BigClassName").getBytes("iso8859_1"));
Statement stmt_ChannelDEL=conn.createStatement();
String Sqldel="delete from hl_news where id=" + ID;

if (shan>0)
{
