Python类的“类”在Javascript中 [英] Python-Like "Classes" in Javascript

问题描述

我想知道如何在Javascript中使用类似于Python中的类。使用下面列出的Python类和函数：

I was wondering how one would go about making "classes" similar to those in Python in Javascript. Take the Python classes and functions listed here:

class one:
    def foo(bar):
        # some code

函数foo将被调用 one.foo （bar）。

JS等效项是什么？我怀疑这将是这样的：

The function "foo" would be called with one.foo(bar).
What would the JS equivalent be? I suspect it would be something like this:

var one = {
    foo: function(bar) {
        // JavaScript
    }
};

谢谢。

推荐答案

在Javascript中创建类的本地方法是首先定义构造函数：

The native way to create classes in Javascript is to first define the constructor:

function MyClass() {
}

和原型：

MyClass.prototype = {
    property: 1,
    foo: function(bar) {
    }
};

然后你可以创建MyClass的实例：

Then you can create instance of MyClass:

var object = new MyClass;
object.foo();

添加静态方法：

MyClass.staticMethod = function() {};

MyClass.staticMethod();

扩展MyClass：

function SubClass() {
}
SubClass.prototype = new MyClass;
SubClass.prototype.bar = function() {
};

var object = new SubClass;
object.foo();
object.bar();
