在Thinkphp中使用ajax实现无刷新分页的方法

在Thinkphp目录的Lib\ORG\Util\目录里新建AjaxPage.class.php,写入一下内容：

class AjaxPage {
// 分页栏每页显示的页数

// 页数跳转时要带的参数

// 默认分页变量名

$this->nowPage = $this->totalPages;
}
$this->firstRow = $this->listRows*($this->nowPage-1);
}
public function setConfig($name,$value) {

}
//上下翻页字符串
$upRow = $this->nowPage-1;
$downRow = $this->nowPage+1;
if ($upRow>0){
$upPage="<a id='big' href='javascript:".$this->ajax_func."(".$upRow.")'>".$this->config['prev']."</a>";
}else{
$upPage="";
}
if ($downRow <= $this->totalPages){

array('%header%','%nowPage%','%totalRow%','%totalPage%','%upPage%','%downPage%','%first%','%prePage%','%linkPage%','%nextPage%','%end%'),
array($this->config['header'],$this->nowPage,$this->totalRows,$this->totalPages,$upPage,$downPage,$theFirst,$prePage,$linkPage,$nextPage,$theEnd),$this->config['theme']);
return $pageStr;
}
}
?>

控制器里写入以下内容：

<?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('user');
$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 = $credit->order('id desc')->limit($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
$this->assign('list',$data);
$this->assign('page',$page);
$this->display();
}
}
?>

模板文件如下：

<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('User/user', {'p':id}, function(data){ //用get方法发送信息到UserAction中的user方法
$("#user").replaceWith("<div id='user'>"+data+"</div>"); //user一定要和tpl中的一致
});
}
</script>
</head>
<body>
<div id='user'> <!--这里的user和下面js中的test要一致-->
<volist id='list' name='list'> <!--内容输出-->
<{$list.id}>  <{$list.username}><br/>
</volist>
<{$page}> <!--分页输出-->
</div>
</body>
</html>
