JSP实现的简单分页示例
作者：hacker0825
这篇文章主要介绍了JSP实现的简单分页,涉及jsp简单数据库查找及遍历实现分页的相关技巧,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实现的简单分页示例。分享给大家供大家参考，具体如下：
<%@ page language="java" import="java.util.*" contentType="text/html; charset=gbk"%>
<%@ page import="com.yx.page.db.*"%>
<%@ page import="java.sql.*" %>
<html>
<head>
<title>My JSP 'page01.jsp' starting page</title>
</head>
<body>
<center>
<%!
final String jspURL = "page04.jsp";
%>
<%
// 定义如下分页变量
// 1、定义每页要显示的记录数
int lineSize = 10 ;
// 2、定义一个当前是第几页
int currentPage = 1 ;
//接受传过来的当前页
%>
<%
try{
currentPage = Integer.parseInt(request.getParameter("cp"));
}catch(Exception e){
e.printStackTrace();
}
%>
<%
Connection conn = null;
PreparedStatement pStmt = null;
ResultSet rs = null;
GetConnection getConnection = new GetConnection(); //自定义数据库连接操作 DAO
%>
<script language="javascript">
function openPage(curpage){
document.form1.cp.value=curpage;
document.form1.submit();
}
</script>
<form action="<%=jspURL%>" method="post" name="form1">
<input name="button1" type="button" value="首页" onClick="openPage(1)">
<input name="button2" type="button" value="上一页" onClick="openPage(<%=currentPage-1%>)">
<input name="button3" type="button" value="下一页" onClick="openPage(<%=currentPage+1%>)">
<input name="button4" type="button" value="尾页">
<input name="cp" type="hidden" value="" />
</form>
<table width="80%" border="1">
<%
try{
String strSql= "select * from person";
pStmt = getConnection.getPreStatement(strSql);
rs = pStmt.executeQuery();
%>
<tr>
<td align="center">编号</td>
<td align="center">登陆名称</td>
<td align="center">姓名</td>
<td align="center">密码</td>
<td colspan="2" align="center">操作</td>
</tr>
<%
for(int x=0; x<(currentPage-1)*lineSize; x++){
rs.next();
}
for(int x=0; x<lineSize; x++){
if(rs.next()){
int id = rs.getInt(1);
String uid = rs.getString(2);
String name = rs.getString(3);
String pass = rs.getString(4);
%>
<tr>
<td><%=id%></td>
<td><%=uid%></td>
<td><%=name%></td>
<td><%=pass%></td>
<td>更改</td>
<td>删除</td>
</tr>
<%
}
}
}catch(Exception e){
%>
<h4>系统有错误</h4>
<%
e.printStackTrace();
}finally{
getConnection.getAllClose(conn,pStmt,rs);
}
%>
</table>
</center>
</body>
</html>
希望本文所述对大家JSP程序设计有所帮助。
