JS& ES6：从类中访问静态字段 [英] JS & ES6: Access static fields from within class

问题描述

在ES6中，给出以下示例：

In ES6, given the following example:

export default class MyStyle extends Stylesheet {
   static Color = {
      mainDark: '#000'
   }
   static Comp = {
      ...
      color: Color.mainDark
   }
}

如何访问Color.mainDark（静态字段）？

How can I access Color.mainDark (the static field)?

推荐答案

我认为你的意思是ES.next（可能使用babel stage-0），因为klaemo说你可以按照你的预期访问它，但是如果我记得有一些使用Babel并立即导出类时出现问题，因此在定义类后导出如果您遇到问题：

I assume you mean ES.next (probably using babel stage-0) as klaemo said you can access it as you would expect, however if I recall there were some issues when using Babel and exporting the class immediately, so export after defining the class if you're having problems:

class MyStyle extends Stylesheet {
   static Color = {
      mainDark: '#000'
   }

  someMethod() {
    console.log(MyStyle.Color.mainDark);
  }
}

export default MyStyle;

您可以在 Marian根据类似问题做出的回答，据推测在Babel 6.2.1中确定。

You can read more about the Babel issue in an answer Marian made on a similar question, which is supposedly fixed in Babel 6.2.1.
