JS & ES6: Access static fields from within class

Question

In ES6, given the following example:

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

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

Answer 1

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;

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.

Answer 2

'use strict';

 class User {
   constructor(firstName, lastName) {
   this.firstName = firstName;
   this.lastName = lastName;
 }

 static createGuest() {
    return new User("guest", "site");
   }
 };

 let user = User.createGuest();

  alert( user.firstName ); // guest

  alert( User.createGuest ); // createGuest ... (function)

And const:

'use strict';

class Menu {
 static get elemClass() {
   return "menu"
 }
}

alert( Menu.elemClass ); // menu

use call to context object --- this
