Question

我非常喜欢cakephp ajax的分页。我正在处理一个大型项目，我需要一个带有ajax请求和页面分页的页面。那么让我解释一下我想要的东西。一方面，我想要一个ajax分页（效果非常好），但另一方面，我有一个选择选项下拉列表，它会生成一个过滤器。每当我在下一个请求中单击此下拉列表时，它就会在更改时丢失该事件。此外，它还使用 #content-rooms 创建了一个新的div。请任何人帮助我，因为我已经失去了很多时间。

        $this->Paginator->settings = $options;
        $this->set('rooms', $this->Paginator->paginate());




    }

当ajax请求加载具有 content-rooms 的重复ID的内容时，结果如下。我认为这就是它在下拉列表中丢失事件的原因。

cakephp分页ajax请求不起作用
