javascript - Javascript 拡張クラス

Question

クラスBがクラスAからすべてを継承する(クラスBがAを拡張する)ようにJavaScriptクラスを拡張する正しい/最良の方法は何ですか?

Answer 1

Take a look at Simple JavaScript Inheritance and Inheritance Patterns in JavaScript.

The simplest method is probably functional inheritance but there are pros and cons.

Answer 2

Douglas Crockford has some very good explanations of inheritance in JavaScript:

1. prototypal inheritance: the 'natural' way to do things in JavaScript
2. classical inheritance: closer to what you find in most OO languages, but kind of runs against the grain of JavaScript

Answer 3

   extend = function(destination, source) {   
          for (var property in source) {
            destination[property] = source[property];
          }
          return destination;
    };
