本文實例講述了JSP實現的簡單分頁顯示效果代碼。分享給大家供大家參考，具體如下：
<%@ page contentType="text/html;charset=gb2312" %><%@ page language="java" import="java.sql.*" %><script language="javascript">function newwin(url) {varnewwin=window.open(url,"newwin","toolbar=no,location=no,directories=no,status=no, menubar=no,scrollbars=yes,resizable=yes,width=600,height=450");newwin.focus();return false;}</SCRIPT><script LANGUAGE="javascript">function submit10(){self.location.replace("fenye1.jsp")}</SCRIPT><%//變量聲明java.sql.Connection sqlCon; //數據庫連接對象java.sql.Statement sqlStmt; //SQL語句對象java.sql.ResultSet sqlRst; //結果集對象java.lang.String strCon; //數據庫連接字符串java.lang.String strSQL; //SQL語句int intPageSize; //一頁顯示的記錄數int intRowCount; //記錄總數int intPageCount; //總頁數int intPage; //待顯示頁碼java.lang.String strPage;int i;//設置一頁顯示的記錄數intPageSize = 4;//取得待顯示頁碼strPage = request.getParameter("page");if(strPage==null){//表明在QueryString中沒有page這一個參數，此時顯示第一頁數據intPage = 1;}else{//將字符串轉換成整型intPage = java.lang.Integer.parseInt(strPage);if(intPage<1) intPage = 1;}//裝載JDBC驅動程序Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");//設置數據庫連接字符串strCon = "jdbc:odbc:heyang";//連接數據庫sqlCon = java.sql.DriverManager.getConnection(strCon,"sa","");//創建一個可以滾動的只讀的SQL語句對象sqlStmt =sqlCon.createStatement(java.sql.ResultSet.TYPE_SCROLL_INSENSITIVE,java.sql.ResultSet.CONCUR_READ_ONLY);//準備SQL語句strSQL = "select user_id,user_name from userinfo order by user_id desc";//執行SQL語句并獲取結果集sqlRst = sqlStmt.executeQuery(strSQL);//獲取記錄總數sqlRst.last();//??光標在最后一行intRowCount = sqlRst.getRow();//獲得當前行號//記算總頁數intPageCount = (intRowCount+intPageSize-1) / intPageSize;//調整待顯示的頁碼if(intPage>intPageCount) intPage = intPageCount;%><html><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312"><title>會員管理</title></head><body><form method="POST" action="fenye1.jsp">第<%=intPage%>頁 共<%=intPageCount%>頁<%if(intPage<intPageCount){%><ahref="fenye1.jsp?page=<%=intPage+1%>">下一頁</a><%}%> <%if(intPage>1){%><a href="fenye1.jsp?page=<%=intPage-1%>">上一頁</a><%}%>轉到第:<input type="text" name="page" size="8"> 頁<span><input class=buttonface type='submit' value='GO' name='cndok'></span></form><table border="1" cellspacing="0" cellpadding="0"><tr><th>用戶名</th><th width='8%'>刪除</th></tr><%if(intPageCount>0){//將記錄指針定位到待顯示頁的第一條記錄上sqlRst.absolute((intPage-1) * intPageSize + 1);//顯示數據i = 0;String user_id,user_name;while(i<intPageSize && !sqlRst.isAfterLast()){user_id=sqlRst.getString(1);user_name=sqlRst.getString(2);%><tr><td><%=user_id%></td><td><%=user_name%></td><td width='8%' align='center'><a href="delete.jsp?user_id=<%=user_id%>"onClick="return newwin(this.href);">刪除</a></td></tr><%sqlRst.next();i++;}}%></table></body></html><%//關閉結果集sqlRst.close();//關閉SQL語句對象sqlStmt.close();//關閉數據庫sqlCon.close();%>希望本文所述對大家JSP程序設計有所幫助。
