创建javascript类时使用什么模式? [英] what pattern to use when creating javascript class?

问题描述

用Java创建类的最佳方法是什么(如在OOP中)? 现在，我正在使用以下模式.可以吗?

what is the best way to create classes ( as in OOP) in Javascript ? Right now I am using the following pattern . Is it ok ?

var myclass = (function() {
var _name;
var baseObject = {
    a: 10,
    c: function() {
        return _name + " world " + privateFunc();
        }
};
function privateFunc() { return _name + "-ba"; };

function myclass(name) {
    _name = name;
    this.x = 9;
};
myclass.prototype = baseObject;
return myclass; })();

推荐答案

没有最佳"方法. JavaScript中有一些OOP模式，您提到的是其中一种(也是流行的一种).本质上，它是一种原型(或伪古典)模式，带有用于封装基于私有类的静态变量的闭包.

There is no "best" way. There are a few OOP patterns in JavaScript, and the one you mentioned is one of them (and also a popular one). It is essentially a prototypical (or pseudo-classical) pattern with a closure to encapsulate private class-based static variables.

还有其他模式(例如，道格拉斯·克罗克福德(Douglas Crockford)推荐的功能模式).

There are other patterns (e.g. the functional pattern recommended by Douglas Crockford).

我个人建议使用伪古典模式(尽管哪种模式最好是争论的热点).

I personally recommend the pseudo-classical pattern (although which pattern is best is a hot area of debate).

如果您要使用JavaScript进行OOP，我强烈，建议您考虑采用内置OOP的JavaScript库，例如关闭库.其他库(例如jQuery，MOOtools，Ext等)都具有OOP模块和/或插件.

If you are doing OOP with JavaScript, I strongly recommend that you look into adopting a JavaScript library that has OOP built in, such as The Dojo Toolkit or the Closure Library. Other libraries (e.g. jQuery, MOOtools, Ext etc.) all have OOP modules and/or plugins.
