如何访问在d.ts文件中声明的枚举-Nativescript

Question

I have declared an enum in a d.ts file

declare enum myenum
{
    TYPE_ONE,
    TYPE_TWO,
}

declare class MobileAPI extends NSObject {....}

Now I am accessing the enum in a .ts file like bellow.

this.mobileAPI.addType(myenum.TYPE_ONE,NSString.stringWithString("someString"));

I can compile the app, but getting following JS error

JS ERROR ReferenceError: Can't find variable: myenum

What's am I doing wrong here, please share some idea on this

You are creating a declaration . These should only be used if you have corresponding JavaScript code available .

Fix

Dont use declare and use a file .ts (not .d.ts )

enum myenum // Fixed
{
    TYPE_ONE,
    TYPE_TWO,
}

If you are not the author of the .d.ts file, make sure you load the corresponding JS for the .d.ts file.

Answer 2

You can do inside your d.ts :

export const enum myenum {
  TYPE_ONE = "TYPE_ONE",
  TYPE_TWO = "TYPE_TWO"
}
