二.控制器代碼

public function news(){
       $credit = M('news');
       $count = $credit->count(); //計(jì)算記錄數(shù)
       $limitRows = 5; // 設(shè)置每頁(yè)記錄數(shù)
       
       $p = new \Org\Util\AjaxPage($count, $limitRows,"news"); //第三個(gè)參數(shù)是你需要調(diào)用換頁(yè)的ajax函數(shù)名
       $limit_value = $p->firstRow . "," . $p->listRows;
       
       $data = $credit->order('news_id desc')->limit($limit_value)->select(); // 查詢(xún)數(shù)據(jù)
       $page = $p->show(); // 產(chǎn)生分頁(yè)信息，AJAX的連接在此處生成
       $this->assign('list',$data);
       $this->assign('page',$page);
       $this->display('Ajax_news');    
}

三.模板中代碼 

<html>
 
    <head>
 
        <title>Ajax無(wú)刷新分頁(yè)</title>
 
        <script type="text/javascript" src="__PUBLIC__/Ajax_js/jquery-1.11.1.min.js"></script>
 
        <script type="text/javascript">
 
            function news(id){    //news函數(shù)名 一定要和action中的第三個(gè)參數(shù)一致上面有
 
                 var id = id;
 
                    $.get('{:U("Home/Index/news")}', {'p':id}, function(data){  //IndexAction中的用get方法發(fā)送信息到news方法,注意此處的鏈接
 
                     $("#news").replaceWith("<div  id='news'>"+data+"</div>"); //news一定要和tpl中的一致
 
                });
 
             }          
 
        </script>
 
    </head>
 
    <body>
 
       <div id='news'>   <!--這里的news和上面js中的news要一致-->
 
               <table>
 
               <foreach item='v' name='list'>
 
                     <tr><td>{$v.news_id}</td><td>{$v.news_title}</td></tr>
 
               </foreach>
 
               </table>
 
            {$page}
 
          </div>
 
    </body>
 
</html>
