javascript inheritance example

the name attribute will not affect other instances because the array is of reference type, name is the basic type.How can we solve the problem of instance sharing? Let's take a look... Constructor stealing) Just as we have introduced that prototype definition objects are rarely used separately, prototype chain is rarely used in actual development. To solve the Sharing Problem of reference types, javascript developers introduce the classic

called -Dog.prototype =NewAnimal ();//First time Call theAnimal.apply ( This, arguments);//Second CallIn the example above, we execute the parent class constructor in the subclass constructor, instantiate the parent class on the subclass prototype, this is the combination of inheritance, you can see that it combines the advantages of class-type inheritance and c

The JavaScript language itself does not provide a class, and there is no class inheritance mechanism for other languages, its inheritance is implemented through the object's prototype, but this does not meet the requirements of the COCOS2D-JS engine. Since the COCOS2D-JS engine evolved from cocos2d-x, almost all of the APIs in the early versions of Cocos2d-js coc

object-oriented and object-basedAlmost every developer has a development experience with object-oriented languages such as C + +, C #, and Java. In the traditional object-oriented language, there are two very important concepts-classes and instances. A class defines the behavior and methods of a class of things, whereas an instance is a concrete implementation of classes. We also know that object-oriented programming has three important concepts-encapsulation,

In the previous period, the team had a few excellent internal discussions. Here, I will sort out the Inheritance Mechanism shared by masters of the west wind, add some colloquial descriptions as appropriate, and keep them for record filing. I. Tell a story. Clarify the relationship between Java and JavaScript as Lei Feng tower. Javascript, formerly known as m

This article mainly introduces the "class inheritance" of JavaScript design patterns. This article uses code examples to explain the implementation of class inheritance, if you need a friend, you can refer to the following. Before doing one thing, you must first understand the benefits of doing this thing. I believe that no one is willing to do things for no reas

As we all know, C # uses traditional class inheritance, but in JS, it is not that simple, because it uses prototype inheritance, the implementation is a little more complicated. [Nonsense] I was very impressed by one of the questions asked by the manager during the interview because I had not answered the question for a long time. How does JavaScript implement

Object are divided into two types: local and referenced. Taking the WD constructor as an example, we can rewrite it with the prototype attribute: Function WD (skill ){ This. skill = skill; } WD. prototype = {sex: 'male '}; Var WD1 = new WD ('html '); Var WD2 = new WD ('css '); Console. log (WD1.sex); // male Console. log (WD2.sex); // male Now, the sex property is stored in the prototype object, which is shared by two instance objects. If the prototy

In the previous article, we introduced the concept of prototypes, learn about the relationships between a constructor, a prototype object, and an instance of three good friends in JavaScript: each constructor has a "Guardian God"--the prototype object, the prototype object also has a constructor in mind, "position", two lovers, But the example but "secretly love" the prototype object, she also retained in t
