javascript object oriented programming interview questions

Two days ago I had a former co-worker who was always asking me JavaScript object-oriented stuff, so just write an article to let him see it, this article mainly wants to explain the JavaScript object-oriented

In fact, object-oriented thinking is independent of the programming language, for example, in C #, in a static class of static methods, in accordance with procedural development calls a series of static functions, we can hardly say that this is object-oriented

For a long time (here I want to gloat to say), JS is "a decorative role, complete a very limited function, such as form verification, the language itself has been used as a procedural language, it is difficult to complete complex functions." ”。 But (I'm going to Shine and bitterly say), "and the advent of Ajax makes complex scripts a necessary part, which puts new demands on JavaScript programming, and many

Javascript has almost become a required language for web developers nowadays, but many people only stop at some basic operation layers such as form verification. Currently, object-oriented languages are widely used, we need to learn the Object-Oriented Knowledge of

In my opinion, objects are the most difficult. Because the Object model of Javascript is unique and different from other languages, it is difficult for beginners to master. What is the most difficult part of learning Javascript? In my opinion, objects are the most difficult. Because the Object model of

object There are three ways to refer to a property or method of a class in JavaScript. 1> Point number operator This is one of the most common ways of quoting, and it is not burdensome. In the form of: Object name. property name; Object name. Method name; 2> square brackets Reference In

Sigh is to ease the seriousness of the atmosphere and lead to today's topic, "JavaScript object-oriented programming," Next, we are around the object-oriented several major keywords: encapsulation, inheritance, polymorphism, expan

Javascript is a flexible language that allows us to simulate many machine mechanisms in Object-Oriented Programming and fully use the object-oriented design idea in Javascript, this gre

This article takes the previous JavaScript object-oriented programming (1) Foundation. As mentioned in the previous article, JavaScript does not have a class concept and needs to implement the definition of classes through functions. Let's take an example to illustrate:

Sigh is to ease the seriousness of the atmosphere and lead to today's topic, "JavaScript object-oriented programming," Next, we are around the object-oriented several major keywords: encapsulation, inheritance, polymorphism, expan

JavaScript has been able to simulate object-oriented encapsulation and inheritance, but unfortunately JavaScript's support for polymorphic features is very weak! Other object-oriented language polymorphism is generally implemented by method overload and virtual method to ach

Function is used to create functions or methods in javascript. To implement object-oriented programming, class is an indispensable role and the main character. However, javascript does not have the concept of a class. The so-called class is also simulated. The class members

inherited prototype chain. An article has been written in very detailed, please refer to: http://bbs.51js.com/thread-84148-1-1.html the object-oriented development of JS Since I am not a front developer, I have seen the project limited and only talk about my own experience. I developed the B/s, commonly used two architectures, one is mainly CGI, by the background language to generate HTML,JS just do s

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

child class instances might be affected by a property that has a reference type value on the prototype object (because the parent class's properties are all copied over on the subclass, the Parent property is overwritten). But in this way, subclasses extend inconvenient when we want to extend the parent class, such as when the parent class becomes a function Sup (a, B). So, here's an improved notation (the idea I've been told by an interviewer):Sup.a

The factory mode and constructor mode are introduced in javaScript object-oriented design and Javascript object-oriented design, as well as their advantages and disadvantages, today, we will continue to explain the prototype mode.

(stuinfo); This style of operation is very similar to C #. The above code is static constructs the student object, the student object's structure is determined. In other programming languages the general object structure is not easily modified once it is determined, but the object structure in

Javascript object-oriented programming example code, the code is also relatively basic, do not know a friend can refer to the articles released before the home of feet. The Code is as follows:

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
