Converting enums to array of values (Putting all JSON values in an array)

I use this method Enums in JavaScript? to create enums in our code..

So 

var types = {
  "WHITE" : 0,
  "BLACK" : 1
}

Now the issue is when I want create validations anywhere, I have to do this;

model.validate("typesColumn", [ types.WHITE, types.BLACK ]);

Now is there a way I can just simple convert the values in types to an array so that I don't have to list all of the values of the enum?

model.validate("typesColumn", types.ValuesInArray]);

EDIT: I created a very simple enum library to generate simple enums npm --save-dev install simple-enum (https://www.npmjs.com/package/simple-enum)

Solution

  • I would convert the map into an array and store it as types.all. You can create a method that does it automatically:

    function makeEnum(enumObject){
   var all = [];
   for(var key in enumObject){
      all.push(enumObject[key]);
   }
   enumObject.all = all;
}
