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>
