Ensure that a class has only one instance and provides a global access point to it.When you click the login button, a login floating window appears on the page, which is unique. No matter how many login buttons are clicked, this
The following 23 design patterns are mentioned in the design pattern book:Abstractfactory: Provides an interface to create a series of related or interdependent objects without specifying their specific classes.Adapter: Transforms the interface of a class into another interface that the customer wants. The adapter mode makes it possible for those classes that wou
the parent class, the post-condition (that is, the return value of the method) of the method is stricter than that of the parent class;
Dependency inversion principle:
Invert dependency to dependency Interface
Upper-layer modules should not depend on lower-layer modules. They all depend on an abstraction;
Parent classes cannot depend on child classes. They all depend on abstract classes;
Abstraction cannot depend on or depend on abstraction;
Interface isolation principle:
The dependence of a

Introduction: the online criticism of MFC is endless. It is not good to say that it is similar to MFC. Some netizens even use "bad" to describe MFC. I have been learning mf c for some time. I feel that my level of MFC is moderate, and there is still a gap between my skills in using it. I have a deep understanding of the "pain" of learning MFC, so I usually try to avoid using MFC at work. A few days ago, I saw a discussion about the

So far, I have finished learning several design patterns of the created model. Let's take a look at them.
It takes a short time. It is better to create a model that is relatively simple and will not be so smooth in the future. since there is no real practice in the project, so far, I think I have not mastered it, just a little understanding of the design model.

Learning JavaScript design patterns: class inheritance and javascript Design Patterns
Before doing one thing, you must first understand the benefits of doing this thing, and believe that no one is willing to do things for no reason. In general, when designing a class, we actually want to reduce repetitive code and use
type T, and the return value of the same method (overloaded or overridden) of the subclass is S, then the Richter substitution principle requires s to be less than or equal to T.
3. Dependency inversion principle (DIP):
The high-level module should not rely on the bottom low-layer module, both should rely on its abstraction;
Abstraction should not depend on details;
Detail should be dependent on abstraction.
