无法理解从私有闭包中包含的类创建对象

Question

我是一名刚开始学习的学生，我一直在与 accessing/running 通过闭包中的 Class 创建的对象进行反复斗争。我掌握了 Class 创建对象的想法，但是当它们被包裹在一个私有闭包中时——我的大脑在翻译过程中丢失了一些东西。

我知道我理解这个的问题必须很简单。我只需要一点外界帮助。

我有两种情况。

场景 1：输出：女人{年龄：20，年级："B"，class："sophomore"}

//WORKING SCENARIO #1
var Woman = function(a, b, c){
        this.age = a;
        this.grade = b;
        this.class = c;
}

var diana = new Woman(20, 'B','sophomore');
console.log(diana);
//END WORKING SCENARIO

情景 2：输出：女人{年龄：未定义，年级：未定义，class：未定义}

//WHAT I'M STRUGGLING WITH
var privateOne = (function(a,b,c){

    var Woman = function(a, b, c){
        this.age = a;
        this.grade = b;
        this.class = c;
    }

    var person = new Woman(a,b,c);

    return {
        showWoman : function(d,e,f){
            return person;
        }
    }

})();

var mary = privateOne.showWoman(20, 'B','sophomore');
console.log(mary);
//END WHAT I'M STRUGGLING WITH

Answer 1

听起来您需要在调用 showWoman 时实例化 Woman:

var privateOne = (function(a,b,c){
    var Woman = function(a, b, c){
        this.age = a;
        this.grade = b;
        this.class = c;
    }

    return {
        showWoman : function(a, b, c){
            return new Woman(a, b, c);;
        }
    }
})();

var mary = privateOne.showWoman(20, 'B','sophomore');
console.log(mary);
