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 " 
}

最近在使用TypeScript 1.0.1时遇到了这个问题，并以这种方式解决了:

enum IEvents {
        /** A click on a product or product link for one or more products. */
        CLICK,
        /** A view of product details. */
        DETAIL,
        /** Adding one or more products to a shopping cart. */
        ADD,
        /** Remove one or more products from a shopping cart. */
        REMOVE,
        /** Initiating the checkout process for one or more products. */
        CHECKOUT,
        /** Sending the option value for a given checkout step. */
        CHECKOUT_OPTION,
        /** The sale of one or more products. */
        PURCHASE,
        /** The refund of one or more products. */
        REFUND,
        /** A click on an internal promotion. */
        PROMO_CLICK
}

var Events = [
        'click',
        'detail',
        'add',
        'remove',
        'checkout',
        'checkout_option',
        'purchase',
        'refund',
        'promo_click'
];

function stuff(event: IEvents):boolean {
        // event can now be only IEvents constants
        Events[event]; // event is actually a number that matches the index of the array
}
// stuff('click') won't work, it needs to be called using stuff(IEvents.CLICK)

更新:TypeScript 3.4

你可以简单地使用const:

const AwesomeType = {
   Foo: "foo",
   Bar: "bar"
} as const;

打字稿2.1

这也可以用这种方式完成。希望它能帮助到一些人。

const AwesomeType = {
    Foo: "foo" as "foo",
    Bar: "bar" as "bar"
};

type AwesomeType = (typeof AwesomeType)[keyof typeof AwesomeType];

console.log(AwesomeType.Bar); // returns bar
console.log(AwesomeType.Foo); // returns foo

function doSth(awesometype: AwesomeType) {
    console.log(awesometype);
}

doSth("foo") // return foo
doSth("bar") // returns bar
doSth(AwesomeType.Bar) // returns bar
doSth(AwesomeType.Foo) // returns foo
doSth('error') // does not compile

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。

https://github.com/djabraham/ts-enum-tools

使用typescript@next中提供的自定义转换器(https://github.com/Microsoft/TypeScript/pull/13940)，您可以从字符串字面类型创建字符串值的枚举对象。

请查看我的npm包，ts-transformer-enumerate。

使用示例:

// The signature of `enumerate` here is `function enumerate<T extends string>(): { [K in T]: K };`
import { enumerate } from 'ts-transformer-enumerate';

type Colors = 'green' | 'yellow' | 'red';
const Colors = enumerate<Colors>();

console.log(Colors.green); // 'green'
console.log(Colors.yellow); // 'yellow'
console.log(Colors.red); // 'red'

我在TypeScript 1.5中尝试过，如下所示，它对我来说很有效

module App.Constants {
   export enum e{
        Hello= ("Hello") as any,
World= ("World") as any
    }
}
