vue实现页面滚动到底部刷新

if (!empty($_POST['sort'])) $parm['sort'] = $_POST['sort'];
if (!empty($_POST['page'])) $parm['page'] =1;
//获取前台传过来的size值如果不为空就设置请求接口时多一个size参数
if (!empty($_POST['size'])) $parm['size'] = $_POST['size'];
//调用接口
$data = $this->http('service/article.php', $parm);
echo json_encode($data);
}
