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。
