return $pageStr;
}
}
?>

Write the following content in the controller:

<?php
class UserAction extends Action{
public function user(){
import("ORG.Util.AjaxPage");// 导入分页类 注意导入的是自己写的AjaxPage类
$credit = M(&#39;user&#39;);
$count = $credit->count(); //计算记录数
$limitRows = 5; // 设置每页记录数
$p = new AjaxPage($count, $limitRows,"user"); //第三个参数是你需要调用换页的ajax函数名
$limit_value = $p->firstRow . "," . $p->listRows;
$data = $credit->order(&#39;id desc&#39;)->limit($limit_value)->select(); // 查询数据
$page = $p->show(); // 产生分页信息，AJAX的连接在此处生成
$this->assign(&#39;list&#39;,$data);
$this->assign(&#39;page&#39;,$page);
$this->display();
}
}
?>

The template file is as follows:

<html>
<head>
<title>Ajax无刷新分页</title>
<script type="text/javascript" src="../Public/jquery-1.7.2.min.js"></script>
<script type="text/javascript">
function user(id){ //user函数名 一定要和action中的第三个参数一致上面有
var id = id;
$.get(&#39;User/user&#39;, {&#39;p&#39;:id}, function(data){ //用get方法发送信息到UserAction中的user方法
$("#user").replaceWith("<p id=&#39;user&#39;>"+data+"</p>"); //user一定要和tpl中的一致
});
}
</script>
</head>
<body>
<p id=&#39;user&#39;> <!--这里的user和下面js中的test要一致-->
<volist id=&#39;list&#39; name=&#39;list&#39;> <!--内容输出-->
<{$list.id}>  <{$list.username}><br/>
</volist>
<{$page}> <!--分页输出-->
</p>
</body>
</html>
