本文實例講述了PHP+ajax分頁實現方法。分享給大家供大家參考,具體如下:
HTML代碼如下:
<html> <head> <meta http-equiv="Content-Language" content="en" /> <meta name="GENERATOR" content="PHPEclipse 1.0" /> <meta http-equiv="Content-Type" content="text/html; charset=GB2312" /> <title>title</title> <mce:script type='text/javascript'><!-- var http_request=false; function send_request(url){//初始化,指定處理函數,發送請求的函數 http_request=false; //開始初始化XMLHttpRequest對象 if(window.XMLHttpRequest){//Mozilla浏覽器 http_request=new XMLHttpRequest(); if(http_request.overrideMimeType){//設置MIME類別 http_request.overrideMimeType("text/xml"); } } else if(window.ActiveXObject){//IE浏覽器 try{ http_request=new ActiveXObject("Msxml2.XMLHttp"); }catch(e){ try{ http_request=new ActiveXobject("Microsoft.XMLHttp"); }catch(e){} } } if(!http_request){//異常,創建對象實例失敗 window.alert("創建XMLHttp對象失敗!"); return false; } http_request.open("GET",url,true); http_request.onreadystatechange=processrequest; //確定發送請求方式,URL,及是否同步執行下段代碼 http_request.send(null); } //處理返回信息的函數 function processrequest(){ if(http_request.readyState==4){//判斷對象狀態 if(http_request.status==200){//信息已成功返回,開始處理信息 document.getElementById('result').innerHTML=http_request.responseText; } else{ //頁面不正常 alert("您所請求的頁面不正常!"); } } } function dopage(url) { document.getElementById('result').innerHTML="正在讀取數據..."; send_request(url); } // --></mce:script> </head> <body bgcolor="#FFFFFF" text="#000000" link="#FF9966" vlink="#FF9966" alink="#FFCC99"> <div id='result'> </div> </body> </html>
php代碼如下:
header("Content-type: text/html;charset=GBK");// $link=mysql_connect('localhost','root','root'); mysql_select_db('test'); mysql_query("SET NAMES 'GBK'"); $num=5;//每頁顯示5條 $sql="select * from article "; //總共有多少記錄 $resultt=mysql_query($sql); //獲取數據庫總記錄數 $total=mysql_num_rows($result); echo $total; //總共有多少頁 $pagecount=$total/$num; //獲取當前頁 $currentPage=isset($_GET['page'])?intval($_GET['page']):1; //查詢條數 $offset=($currentPage-1)*$num; //下一頁 $nexpage=($currentPage==$pagecount?0:$currentPage+1); //上一頁 $prepg=$currentPage-1; $url='ajax.php'; //根據條數查詢信息 $strSQL="select * from article limit $offset,$num"; $pagecontrol="當前第".$currentPage."頁" ; $pagecontrol.="共".$pagecount."頁"; $pagecontrol.="<a href="javascript:dopage(" mce_href="javascript:dopage("'$url?page=1')>首 頁</a> "; if($prepg) $pagecontrol.=" <a href="javascript:dopage(" mce_href="javascript:dopage("'$url?page=$prepg');>上一頁</a> "; else $pagecontrol.=" 上一頁 "; if($nexpage) $pagecontrol.="<a href="javascript:dopage(" mce_href="javascript:dopage("'$url?page=$nexpage');>下一頁</a>"; else $pagecontrol.="下一頁"; $pagecontrol.="<a href="javascript:dopage(" mce_href="javascript:dopage("'$url?page=$pagecount')>尾 頁</a>"; $result1=mysql_query($strSQL); echo "<table border=1 width=100%>"; echo "<tr>"; echo "<td>編 號</td><td>標 題</td><td>新聞類型</td>"; echo "</tr>"; while($row=mysql_fetch_array($result1)) { echo "<tr>"; echo "<td>$row[id]</td><td>$row[title]</td><td>$row[classname]</td>"; echo "</tr>"; } echo "</table>"; echo "<br/>"; echo $pagecontrol;
希望本文所述對大家PHP程序設計有所幫助。
