javascript es2015 class

4. Constructor + prototype assemble a class directly; the same constructor will assemble the same type The previous few learned that JavaScript writing classes were based on constructors and prototypes. In that case, we write a tool function to write the class. Copy Code code as follows: /** * $class

I. Opening (Part of the following text is from the content of the compiled books, and part of the text is from the experience)Javascript is an object-oriented language. Javascript objects include local objects, built-in objects, and custom objects. Both the local object and the built-in object are independently implemented by ecmascript on the host. The local object and built-in object mentioned here are ac

Most classes in javascript are represented by function functions, and most of them are defined in json format later. Classes in javascript are represented by function functions, as follows: The Code is as follows: Function Student (){// Define the field in the Student class and grant the initial value. However, the access permission for this field is public.Th

) {private1 = obj; } THIS.PUBLICMETHOD2 = function () {//console.log (this); Returns an instance of the object return private1; }}) (var B1 = new A (), var b2 = new A (); B1.publicmethod1 (' s '); Console.log (B1.PUBLICMETHOD2 ()); Console.log (b2.pub LICMETHOD2 ());First Class library Base.jsAfter understanding the basic object-oriented and prototype, let's encapsulate our first class library. Thi

Moment.js not to miss the awesome JavaScript date processing class LibraryKey Features: 3.2KB Ultra Lightweight Independent class library, meaning that you don't have to pour a bunch of JS Date processing supports UNIX timestamp, String, date of specified format Date processing: Plus, minus date Date display: Includes date display options

Shawl. Qiu Javascript CodeFormatting class/Styler, styleengine V1.1 Note:V1.1 is completed only in V1.0 as plannedSupports CSS,There are no other differences, so we will not introduce them. However, it should be noted that,Since CSS is generally only a level {}However, you can also define... In the @ media parameter...For efficiency reasons, the publisher does not consider the latter's definition, that i

In object-oriented programming, classes (Class) are templates of objects (object) that define properties and methods that are common to the same set of objects (also known as "instances"). The JavaScript language does not support "classes," but you can simulate "classes" in some alternative way. First, the structural function method This is the classical method, is also the textbook must teach the method

some basic terms!1. prototype)In fact, the prototype of an object is the prototype value of the constructor. All functions have a prototype attribute. When a function is created, it is automatically created and initialized, the initialization value is an object. This object comes with a constructor attribute, which refers to the constructor associated with the prototype.Function PeopleHope (money, house){This. money = money;This. house = house;}PeopleHope. prototype. hope = function () {documen

allow the next regular expression to continue to match. Because the above repetition is "greedy". In JavaScript regular expressions, you can repeat in a non greedy way, which is a feature of PERL5, but is implemented by JavaScript.Define a method that is not greedy: Simply add a question mark after the repeating character, for example:?? ,? +,? * even {1,5}? This is also possible.Examples are as follows:Normally,/a+/matches one or more character a, a

This article focuses on parsing the javascript class inheritance mechanism, so that you can understand how javascript implements the concept of "inheritance" from the underlying layer. Currently, javascript implementation inheritance is not implemented through the "extend" keyword, but through the constructor function

and a distributed database system... and a bunch of other methods that Barabara uses to handle high concurrency and massive data access. I want to say, is it meaningful? Misunderstanding of front-end framework The value of a website lies in what value it can provide to users, what the website can do, and not in how it does it, therefore, when the website is still very small, it is worth the candle to pursue the website architecture framework. The same applies to front-end frameworks. for a simp

Is it very convenient to process JSON object data like a database? Today, we will introduce TaffyDB, a great javascript class library, which can help you process JSON objects in the same way as databases.Main featuresThe class library is very small and has good performance.Powerful data selection EngineSupports different database operations, such as insert, updat

Currently, javascript implementation inheritance is not implemented through the "extend" keyword, but through the constructor function and prototype attributes. First, create an animal class.Js CodeCopy codeThe Code is as follows:Var animal = function () {// This is the constructor function.This. name = 'pipi ';This. age = 10;This. height = 0;}// Create an animal instanceVar a1 = new animal (); The difference between constructor and other common funct

The previous paragraph is a piece of work because of the need to write a JavaScript package to give the tool class, technology is limited, Miss Spray, thank you for your support.1. The following is the JavaScript Ajax tool class.functioncreatexmlhttprequest () {varreq; if(window. XMLHttpRequest) {//compatible with browsers that are non-IE compatible and IE7req =N

I recently checked the JavaScript data and found a function: Copy Code code as follows: function format (s) { var args = arguments; var pattern = new RegExp ("% ([1-" + Arguments.length + "])", "G"); return String (s). Replace (Pattern,function (word,index) { return Args[index]; }); } Test window.onload = alert (Format ("and"%1 want to know whose%2 "," Papers "," shirt "," wear ")); And the papers want to know whose
