这里有一个相当干净的解决方案，它允许继承，使用TypeScript 2.0。我没有在早期的版本上尝试过。

附加条件:该值可以是任何类型!

export class Enum<T> {
  public constructor(public readonly value: T) {}
  public toString() {
    return this.value.toString();
  }
}

export class PrimaryColor extends Enum<string> {
  public static readonly Red = new Enum('#FF0000');
  public static readonly Green = new Enum('#00FF00');
  public static readonly Blue = new Enum('#0000FF');
}

export class Color extends PrimaryColor {
  public static readonly White = new Enum('#FFFFFF');
  public static readonly Black = new Enum('#000000');
}

// Usage:

console.log(PrimaryColor.Red);
// Output: Enum { value: '#FF0000' }
console.log(Color.Red); // inherited!
// Output: Enum { value: '#FF0000' }
console.log(Color.Red.value); // we have to call .value to get the value.
// Output: #FF0000
console.log(Color.Red.toString()); // toString() works too.
// Output: #FF0000

class Thing {
  color: Color;
}

let thing: Thing = {
  color: Color.Red,
};

switch (thing.color) {
  case Color.Red: // ...
  case Color.White: // ...
}

alert(e[1] + ' ' + e.somestr);

我只是声明了一个接口，并使用该类型的变量访问枚举。保持接口和枚举同步实际上很容易，因为如果枚举中有什么变化，TypeScript会报错，就像这样。

typeof EAbFlagEnum类型的参数不可赋值 参数类型为“IAbFlagEnum”。属性“Move”类型缺失 “typeof EAbFlagEnum”。

这种方法的优点是在各种情况下使用enum(接口)不需要类型强制转换，因此支持更多类型的情况，例如switch/case。

// Declare a TypeScript enum using unique string 
//  (per hack mentioned by zjc0816)

enum EAbFlagEnum {
  None      = <any> "none",
  Select    = <any> "sel",
  Move      = <any> "mov",
  Edit      = <any> "edit",
  Sort      = <any> "sort",
  Clone     = <any> "clone"
}

// Create an interface that shadows the enum
//   and asserts that members are a type of any

interface IAbFlagEnum {
    None:   any;
    Select: any;
    Move:   any;
    Edit:   any;
    Sort:   any;
    Clone:  any;
}

// Export a variable of type interface that points to the enum

export var AbFlagEnum: IAbFlagEnum = EAbFlagEnum;

使用变量，而不是枚举，可以产生所需的结果。

var strVal: string = AbFlagEnum.Edit;

switch (strVal) {
  case AbFlagEnum.Edit:
    break;
  case AbFlagEnum.Move:
    break;
  case AbFlagEnum.Clone
}

标记是我的另一个需要，所以我创建了一个NPM模块，添加到这个例子中，并包括测试。

这对我来说很管用:

class MyClass {
    static MyEnum: { Value1; Value2; Value3; }
    = {
        Value1: "Value1",
        Value2: "Value2",
        Value3: "Value3"
    };
}

or

module MyModule {
    export var MyEnum: { Value1; Value2; Value3; }
    = {
        Value1: "Value1",
        Value2: "Value2",
        Value3: "Value3"
    };
}

更新:在发布这篇文章后不久，我发现了另一种方法，但忘记发布更新(然而，上面已经有人提到过了):

enum MyEnum {
    value1 = <any>"value1 ", 
    value2 = <any>"value2 ", 
    value3 = <any>"value3 " 
}

export enum PaymentType {
                Cash = 1,
                Credit = 2
            }
var paymentType = PaymentType[PaymentType.Cash];

非常非常简单的Enum string (TypeScript 2.4)

import * from '../mylib'

export enum MESSAGES {
    ERROR_CHART_UNKNOWN,
    ERROR_2
}

export class Messages {
    public static get(id : MESSAGES){
        let message = ""
        switch (id) {
            case MESSAGES.ERROR_CHART_UNKNOWN :
                message = "The chart does not exist."
                break;
            case MESSAGES.ERROR_2 :
                message = "example."
                break;
        }
        return message
    }
}

function log(messageName:MESSAGES){
    console.log(Messages.get(messageName))
}
