這篇文章主要介紹了jsp分頁顯示完整實(shí)例,以文章管理頁面為例詳細(xì)分析了jsp的分頁顯示實(shí)現(xiàn)技巧,具有一定參考借鑒價(jià)值,需要的朋友可以參考下

本文實(shí)例講述了jsp分頁顯示的實(shí)現(xiàn)方法。分享給大家供大家參考。

具體實(shí)現(xiàn)方法如下：

代碼如下:

<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>

< file ="../inc/ChkPwd.jsp"%>

< file="../DB.jsp"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">

<body>

</tr>

<td height="25" background="images/admin_bg_1.gif" class="t2">|

String op;

String ID = request.getParameter("id");

op = request.getParameter("op");

if(op==null){

op = "my";

}

if (op.equals("del") && ID!=null){

String bbb = new String(request.getParameter("BigClassName").getBytes("iso8859_1"));

Statement stmt_ChannelDEL=conn.createStatement();

String Sqldel="delete from hl_news where id=" + ID;

int shan=stmt_ChannelDEL.executeUpdate(Sqldel);

if (shan>0)

{

out.print("<script type="text/javascript"> alert("已成功刪除！"); window.location.href='Hanye_Manages.jsp?BigClassName="+bbb+"'; </script>");

}

stmt_ChannelDEL.close();

return ;

}

Statement stmtA=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_READ_ONLY);

String SqlA="Select * from hl_smallclass WHERE bigname='行業(yè)新聞' order by id asc";

ResultSet RsA=stmtA.executeQuery(SqlA);

while (RsA.next()) {

<a class='t2' href='Hanye_Manages.jsp?modi=新聞&BigClassName=<%=RsA.getString("smallname")%>'><%=RsA.getString("smallname")%></a> |

}

RsA.close(); //關(guān)閉記錄集對(duì)象

stmtA.close(); //關(guān)閉語句對(duì)象
