问题描述

我发现 http://ejohn.org/blog/simple-javascript-inheritance /，这正是我要搜索的内容，但我想知道它是否仍然有效以及是否会引起任何问题.

推荐答案

许多现代图书馆现在都在使用经典继承.其核心方法如下(Stoyan Stefanov撰写的JavaScript Patterns，第127页):

Many modern libraries use classical inheritance now. Its core method is the following (JavaScript Patterns by Stoyan Stefanov, page 127):

function inherit(C, P) { 
    var F = function () {}; 
    F.prototype = P.prototype; 
    C.prototype = new F(); 
    C.uber = P.prototype; 
    C.prototype.constructor = C; 
} 

使用它的项目示例是:

• Google关闭
• YUI
• ExtJS

• Google Closure
• YUI
• ExtJS
