object oriented javascript interview questions

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 programming, in contrast, like jquery and ExtJS such a good

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

JavaScript object-oriented is totally accidental, because most of the time I work in a non-graphic environment, sometimes when I write JavaScript and ajax, even when I get involved in the work of the web Client, the most important thing is writing a function. I have never considered using the advanced

by the point number follow the rules of the identifiers. However, the use of a non-identifier naming method is not generally advocated. 3> using the Eval function The Eval function is a good choice if you do not want to use a variable to pass a variable or method name, and you do not want to use conditional judgment. Eval receives a parameter of type string and then executes the string as code in the context, returning the result of execution. This is where the Eval function is used. As follows

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

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, expand. Encapsulation: The pattern of creating obj

In JavaScript, we can say that everythingisobject, so what is an object? An object is a set of variables and functions. In other object-oriented languages, objects are instantiated by classes. JavaScript is a prototype-based

This article is translated from ScottAllenPrototypesandInheritanceinJavaScript, a Microsoft cool-man. This article gives a detailed analysis and explanation of Prototype and Prototype inheritance. It is one of the best works to understand JSOO. I. Preface This article is translated from Microsoft's cool man Scott Allen Prototypes and Inheritance in JavaScript. This article gives a detailed analysis on what Prototype is and why Prototype can be used

In object-oriented languages, overloading is an important feature, while JavaScript, a self-proclaimed object-oriented language, does not directly provide overload functions. I have discussed the JavaScript

result of the invocation of the prototype inheritance method, and the problem is the same, not repeated here. By the result of the O.method () call, we see that the method defined on the parent prototype will not inherit from the quilt class. The result of the call to O.method3 () shows that the instance method defined in the subclass also cannot access the private instance members defined in the parent class. Finally, we see that static members are also not inherited by the results of the Subc

Interfaces are one of the most useful features in the object-oriented Javascript toolbox. As we all know, in the design mode, GOF says: interface-oriented programming, rather than implementation-oriented programming, is enough to show how important interfaces are in the

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 greatly improves code reuse, reduces inter-modul

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: Copy Code code as follows: functi

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 and Private Members are simulated through the
