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：

$this->nowPage = $this->totalPages;

}

}

public function setConfig($name,$value) {

if(isset($this->config[$name])) {

unset($params[$p]);

}

//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>
