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。

TypeScript < 2.4

/** Utility function to create a K:V from a list of strings */
function strEnum<T extends string>(o: Array<T>): {[K in T]: K} {
  return o.reduce((res, key) => {
    res[key] = key;
    return res;
  }, Object.create(null));
}

/**
  * Sample create a string enum
  */

/** Create a K:V */
const Direction = strEnum([
  'North',
  'South',
  'East',
  'West'
])
/** Create a Type */
type Direction = keyof typeof Direction;

/** 
  * Sample using a string enum
  */
let sample: Direction;

sample = Direction.North; // Okay
sample = 'North'; // Okay
sample = 'AnythingElse'; // ERROR!

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)

在TypeScript 0.9.0.1中，尽管会出现编译器错误，但编译器仍然可以将ts文件编译为js文件。代码工作如我们所料，Visual Studio 2012可以支持自动代码补全。

更新:

在语法上，TypeScript不允许我们用字符串值创建enum，但我们可以破解编译器:p

enum Link
{
    LEARN   =   <any>'/Tutorial',
    PLAY    =   <any>'/Playground',
    GET_IT  =   <any>'/#Download',
    RUN_IT  =   <any>'/Samples',
    JOIN_IN =   <any>'/#Community'
}

alert('Link.LEARN:    '                     + Link.LEARN);
alert('Link.PLAY:    '                      + Link.PLAY);
alert('Link.GET_IT:    '                    + Link.GET_IT);
alert('Link[\'/Samples\']:    Link.'        + Link['/Samples']);
alert('Link[\'/#Community\']    Link.'      + Link['/#Community']);

操场上

  Clone     = <any> "clone"
}

// Create an interface that shadows the enum

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
}

为什么不直接使用本地方式访问枚举的字符串呢?

enum e {
  WHY,
  NOT,
  USE,
  NATIVE
}

e[e.WHY] // this returns string 'WHY'
