wireframe prototype

Javascript advanced-prototype, 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

The relationship between prototype and _ proto _ in Javascript is described in detail. prototype _ proto _ Preface When I learned the prototype, I felt my head was too big )/~~ In particular, prototype and _ proto _ are too stupid to find out more information. Based on your understanding, the following is a summary: 1.

I. Common objects and Function objectsIn JavaScript, everything is Object! But the object is also different. is divided into ordinary objects and function objects, object, function is JS comes with the functions of the object. The following examples illustrateFunction F1 () {};var F2 = function () {};var F3 = new Function (' str ', ' Console.log (str) ');var O3 = new F1 ();var O1 = {};var O2 =new Object ();Console.log (typeof Object); functionConsole.log (typeof Function); functionConsole.log (t

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

three objects are created by the new function (). There are two ways to create objects in JavaScript: Object literals and the use of new expressions, the creation of O1 and O2 corresponds to the two ways, focusing on the O3, if understood in Java and C #, O3 is the F1 instance object, O3 and F1 are the same type, At least I used to think so. So how do you understand it? It's easy to see if O3 is created by the new function, obviously not, since it's not a function object, it's a normal object

I have been studying js recently and have many questions. It is confused by the prototype. The question comes from: The Code is as follows: Function foo {This. name = 'foo ';}Alert (foo. prototype = Function. prototype); // false. At that time, I never figured out why the prototype of foo is not Function.

Design Pattern-prototype pattern (06), design pattern prototypeDefinition Prototype Pattern is a simple design mode. The prototype is Specify the kind of objects to create using a prototypical instance, and create new objects by copying this prototype. it means to use a prototype
