本文執行個體講述了JSP實現的簡單分頁樣本。分享給大家供大家參考,具體如下:
<%@ 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"; %> <% // 定義如下分頁變數 // 1、定義每頁要顯示的記錄數 int lineSize = 10 ; // 2、定義一個當前是第幾頁 int currentPage = 1 ; //接受傳過來的當前頁 %> <% 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(); //自訂資料庫連接操作 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="首頁" onClick="openPage(1)"> <input name="button2" type="button" value="上一頁" onClick="openPage(<%=currentPage-1%>)"> <input name="button3" type="button" value="下一頁" onClick="openPage(<%=currentPage+1%>)"> <input name="button4" type="button" value="尾頁"> <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">編號</td> <td align="center">登陸名稱</td> <td align="center">姓名</td> <td align="center">密碼</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>刪除</td> </tr> <% } } }catch(Exception e){ %> <h4>系統有錯誤</h4> <% e.printStackTrace(); }finally{ getConnection.getAllClose(conn,pStmt,rs); } %> </table> </center> </body></html>
希望本文所述對大家JSP程式設計有所協助。
