隐藏吸气剂或添加原型对象 [英] hide the getter or add in the proto Object

问题描述

是一种方法，我可以创建一个吸气剂，但将其隐藏或添加到原型中? 在这里的例子中，我使用简单的OBJ. 看起来获取sprite()

is a way how i can create a getter, but hide it or add it in proto ? example here, i use simple OBJ. Look get sprite()

    buttonsData[name] = {
        name:name,
        type:bType,
        slot:slot,
        get sprite() { return this.slot.currentSprite },
    };

但是我发现它非常污染，如何隐藏或编写它，以免在调试终端中干扰我的视线? 我要隐藏 get sprite(){返回this.slot.currentSprite}

but I find it very polluting, how can I hide it or write it so that it does not disturb my eyes in a debug terminal? i want hide get sprite() { return this.slot.currentSprite }

推荐答案

您可以使用prototype /Reference/Global_Objects/Object/create"rel =" nofollow noreferrer> Object.create() ，但请注意，此会稍微恶化 的性能.

You can embed an anonymous prototype using Object.create(), though do note that this slightly deteriorates drastically improves performance for no reason other than "it disturbs my eyes in a debug terminal".

我不主张在性能要求严格的代码中使用这种方法 如何...

buttonsData[name] = Object.assign(Object.create({
    get sprite() { return this.slot.currentSprite }
}), {
    name: name,
    type: bType,
    slot: slot
});

这将创建一个像这样的对象:

This creates an object like this:

{
  name: "Spines",
  slot: Slot,
  type: "sheetsType",
  __proto__: {
    get sprite: function () {...},
    __proto__: Object
  }
}

对于可重用性，最好为每个添加到buttonsData的对象实现class而不是创建匿名prototype:

For re-usability, it would probably be better to implement a class instead of creating an anonymous prototype for each object added to buttonsData:

class ButtonsData {
  constructor (data = {}) {
    Object.assign(this, data)
  }

  get sprite () { return this.slot.currentSprite }
}

并像这样使用它:

buttonsData[name] = new ButtonsData({ name, type: bType, slot })
