在Thinkphp中使用AJAX实现无刷新分页

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

parse_str($parse['query'],$params);
unset($params[$p]);

        }
//上下翻页字符串

            }
        }

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'>   
                    <volist id='list' name='list'>   
                    <{$list.id}>  <{$list.username}><br/>
            </volist>
            <{$page}> 
        </div>

    </body>
</html>
