Add functions to an Enum

Question

Is it possible to add functions to an Enum type in TypeScript?

for example:

enum Mode {
    landscape,
    portrait,

    // the dream...
    toStri         


        

Answer 1

can make enum like by private constructor and static get return object

export class HomeSlideEnum{

  public static get friendList(): HomeSlideEnum {

    return new HomeSlideEnum(0, "friendList");

  }
  public static getByOrdinal(ordinal){
    switch(ordinal){
      case 0:

        return HomeSlideEnum.friendList;
    }
  }

  public ordinal:number;
  public key:string;
  private constructor(ordinal, key){

    this.ordinal = ordinal;
    this.key = key;
  }


  public getTitle(){
    switch(this.ordinal){
      case 0:

        return "Friend List"
      default :
        return "DChat"
    }
  }

}

then later can use like this

HomeSlideEnum.friendList.getTitle();
