Personally think that there is no MVC model with only MC models. Because so-called V (View) in the web frame is not a web layer. It is a layer. The representation must also have its own logic. In this way, it can be seen that each layer has M and C. Only different levels, the role of MC is different. I estimate this is people, I have always wanted to peel off the display and logic, and there is no perfect reason: even the uppermost display layer must also have some control display logic and display layer once complex these logic It must also follow complicated.
