JavaScript prototype and prototype chain Ultimate detailed
I. Common objects and Function objects
In JavaScript, everything is the object! But the objects are also different. It is divided into ordinary object and function object, Object,function is the function object with JS. The following examples illustrate
Function F1 () {};
var F2 = function () {};
var F3 = new Function (' str ', ' Console.l

To understand the prototype in JS, we must first clarify the following concepts1. All the things in JS are objects
2. All things in JS are derived from object, that is, the end point of all the prototype chain points to Object.prototype

Article Description: It's more than just paper-screen print prototypes.
As a user experience research person, should not be unfamiliar with the prototype, whether it is to design physical devices, Web sites or applications, we will use the prototype. In the Internet field, designers often use the code of flash,html and so on to make prototypes, which makes the
A good explanation of JavaScript inheritance, but slow to explain now. Don't say much nonsense, go straight to the chase.Since you want to understand the inheritance, prove that you have a certain understanding of JavaScript object-oriented, such as what is not understood can refer to the "Object-oriented JS basic explanation, Factory mode, constructor mode, prototype mode, mixed mode, dynamic prototype mod

JavaScript we know the prototype properties of objects in JScript, which are used to return references to object type prototypes. We use the prototype property to provide a set of basic functions for the object's class. And a new instance of the object "inherits" the action given to the object's prototype. But how exactly is this
First, prototype (Prototype) mode
The purpose of the prototype pattern is to specify the type of object to be created by giving a prototype object, and then create more objects of the same type with the method of copying the prototype object.

I. Overview:
Use a prototype instance to specify the type of the object to be created and copy the prototype to create a new object. Simply put, an object is copied to generate a new object (Object cloning). The prototype

I. Understanding of javascript prototype
Many programming languages have the concept of classes. We can compare prototypes and classes to see the differences and similarities between them.
1. Class: class is the abstraction of a specific thing, so class is an abstract thing. In object-oriented mode, classes can be used to
The previous article tells the prototype concept of js, and here is a review of the definition of prototype:Prototype is a property of a function and is a prototype object of a Function. It is necessary to refer to the function, which should be remembered.but, It's strange, crossing, have you ever seen a JS code that references prototype like This:function func (
Analysis of Principles and Examples of javascript prototype, prototype chain, and object replication (II)
PrototypePrototype is an important concept in JavaScript object-oriented features and is also a concept that everyone is too familiar. Because in most casesIn the object-oriented language of data, objects are class-based (such as Java and C ++), and objects are the results of class instantiation. InTher
The prototype mode in JavaScript and the prototype in javascript
Objects Created in JavaScript are created in many ways, such as factory mode, constructor mode, and prototype mode:
Its Equivalent prototype:
function Person(){}Person.prototype = {name:"dw",age:20,job:"IT",sayName:function(){alert(this.name);}};var

Constructors Create objectsFirst we use the constructor to create an object:function Person(){}var person = new Person();person.name = ‘tom‘;console.log(person.name) //tomIn this example, person is a constructor, and we create an instance object person with new.Next, get to the point:PrototypeEach function has a prototype attribute, which is the prototype that we often see in various examples, such as:funct
