object oriented javascript es6

Javascript does not have the namespace concept, but to embody the object-oriented thinking, there should be a namespace, just like the package in java ,. the namespace in. net is used to prevent class name conflicts. The same class name does not conflict as long as it belongs to different namespaces. The simplest way to create a namespace is: The Code is as fol

There is no concept of namespaces in JavaScript, but to embody object-oriented thinking, There should be a namespace, just like the namespace in Package,.net in Java, The main function is to prevent class name conflicts, the same class name as long as the different namespaces, will not conflict. The easiest way to create namespaces: Copy Code code as follo

Introduction to javascript Object-Oriented Programming and Object-Oriented Programming The ECMA-262 defines an object as a collection of unordered properties that can contain basic values, objects, or functions" The simplest way t

In small projects for JavaScript use, just write a few function on the line. But in large projects, especially in the development of the pursuit of a good user experience of the site, such as SNS, will use a lot of javascrpt, sometimes the workload of JavaScript than C #, then write a bunch of function, it will appear very messy, messy, even the naming conflict, Management and maintenance are all very troub

This section describes the private and public members of JavaScript. Although JavaScript does not have private and public keywords, it is still the same sentence-as developers, we need to have an object-oriented idea! In fact, it is very simple. I believe you will be clear at a glance after reading the following code a

error, we can see that the above method for global variables did not establish a namespace, global variables for us to pose a danger. So the above wording is right, let's verify: Copy Code code as follows: var box = { Width:2, Height:2, Getarea:function () { The access to the object in return This.width*this.height;//js must be displayed, that is, this is not omitted }, Init:function (w,h) { This.width = W; This.height

All object-oriented languages should have inherited features, and JavaScript is no exception. There are multiple methods to implement inheritance in JavaScript. The following two are common methods. I. call inheritance. first look at the Code: First define a "person" Class The Code is as follows: // HumanPerson =

Some time ago, after learning "ajax self-taught manual", I realized that javascript can still be written like this. I have learned the concepts of classes in java, c #, and vb, and classes have functions such as inheritance, encapsulation, and polymorphism. Javascript is not an object-oriented language, but an explanat

This week's painstaking efforts have turned to the underlying code of several popular JS Script frameworks. Although the code is easy to understand, it has benefited a lot and lamented the greatness of people first ...... The exclamation is to ease the serious atmosphere and bring out the topic to be discussed today, "javascript object-oriented programming". Next

JavaScript object-oriented code is almost different from other common languages (JavaC # C ++. Therefore, it is necessary to give an example here: JavaScript object-oriented code example [Ctrl + A select all Note: If you need t

Because I used to be. net programmers, so even if you are working on the front-end, you are also used to writing js scripts in an object-oriented way. I think if you were or are still a third-generation programmer, you should be familiar with this. Speaking of js object-oriented, we have to mention prototype, the js bu

; for (var i = 0; i { D = a[i].split ('. '); The incoming arguments are segmented with the symbol '. ' and put into the D array. RT = D[0]; Determines whether the first value in the array is undefined and, if not defined, is defined as an empty object {} and assigned to the variable O Eval (' if (typeof ' + rt + ' = ' = ' undefined ') {' + rt + ' = {};} o = ' + rt + '; for (var j = 1; j { /* Loop traversal array d each value as key, add to

The OOP language gives us the ability to customize objects and variable types. Object Oriented Programming JavaScript is an object-oriented programming language (OOP). The OOP language gives us the ability to define our own objects and variable types. Objects have properti

The JAVA,C#,VB know the concept of class, and the class has the functions of inheritance, encapsulation, polymorphism and so on. And JavaScript is not an object-oriented language, it is an interpretive language. But we can also use JavaScript to implement inheritance, polymorphism.

This article illustrates the simplest method of object-oriented tab implementation, sharing for everyone to reference, the specific contents are as follows Effect Chart: 1. Function description Click three buttons to display the corresponding tabs individually2, HTML code description 3, CSS Key code description /*in is the normal state of the tab, the default does not show * /. in

; var_this = This; for(vari = 0; I This. Count; i++){ //Set Index This. Acon[i].index =i; //add an event to a button This. Acon[i].onclick =function() {_this.cur= This. Index; _this.Switch(); }}}tab.prototype.Switch=function(){ //Remove All for(vari = 0; I This. Count; i++){ This. Ain[i].classname = ' in '; This. acon[i].classname = ' con '; } //Displays the current This. ain[ This. Cur].classname = ' in_active '; This. acon[ This. Cur].classname

Javascript object-oriented (2) code encapsulation. If you need code, refer to the following example: Step 1: create a "Mobile Phone type" The Code is as follows: Var MobilePhone = (function (){............})() Step 2: Consider the private attributes of these classes. Here I want to define the number of mobile phones that come out of the instance. The Code

We see how straightforward the concept of inheritance here is, "copy the prototype of a class to another class", OK, code is cheap, look at the codes: function Class1 () {} function Class2 () {} Class2.prototype = Class1.prototype; Class2.moreproperty1 = "Class 2 additional string"; Class2.moremethod1 = function () {alert (' Class 2 additional method ');} /* So, first of all, the CLASS2 has the same prototype as Class1, regardless of the constructor, two classes are equivalent. Subsequently, th

Inheritance is an essential feature of object-oriented systems, but javascript does not have an inherited conceptual mechanism, but we can implement this function on our own. The Code is as follows: Var JsObject ={}| | new Object ();JsObject. extend = function (subClass, superClass ){// First determine whether the s

Examples of javascript object-oriented ideology code can be found below. The Code is as follows:
