Question

我累了。我搜索了几个组件和插件来实现一个带过滤器的简单表。 CakePHP对于那些占主导地位的人来说是美丽的，但对初学者来说却很头疼。我是先生：S

在尝试了几个带有灾难性结果之后，因为没有人按照作者的说法应该有效。我现在使用James Fairhurst的完全FilterCommponent。

我相信有人可以提供帮助。请！

我得到了致命错误：

Answer 1

嗨，如何实施此过滤器，但客户端？

我的意思是JavaScript + jQuery + DataTables。 jQuery DataTables是一个非常简单的插件，可让您以最简单的方式制作过滤器。

您可以拥有不同类型的数据源（HTML表，JSON对象，甚至可以使用Ajax调用，这意味着您可以在CakePHP Controller中执行操作以检索JSON格式的对象列表）。

我做了一个视频，其中有一个关于如何从Ajax调用中调用CakePHP操作的示例：https://www.youtube.com/watch?v=lV6EFXiljBw&index=7&list=PLSUqL2t8VZCqPhogGoP85QcrvmTgW2_VK

我希望你能找到有用的这些信息。问候。
