MVC问题:直接模型-查看交流-为什么? [英] MVC question: direct modell <-> view communication - why?

问题描述

有人可以告诉我，为什么要在MVC模式中直接与视图进行模型通信，为什么不通过控制器呢?

can anybody tell me, why communicates the model direct with the view in the MVC pattern, and why not just throught the controller?

推荐答案

有时使用Controller进行简单的View/Model通讯成本太高.

Sometimes it is too costly to use Controller for simple View/Model communication.

如果您的视图仅显示原始数据而没有任何操作(过滤，可视化，修改...)，则很容易忘记Controller.

If your view just shows raw data without any operation (filtration, visualization, modification ...) it is easy to forget about Controller.

但是这种行为非常容易被滥用 .

But this behavior is so abuse-able sometimes it kills all of the advantages of MVC.

这是 MVP 出现的位置:

MVP(Model-View-Presenter)切断了模型与视图之间的联系，所有事物都通过中间人(Presenter)传递.

MVP (Model-View-Presenter) cuts the connection between model and view and every thing pass through man-in-the-middle (Presenter).
