你可以在最新的TypeScript中使用字符串枚举:

enum e
{
    hello = <any>"hello",
    world = <any>"world"
};

最近我在React中使用的一种更健壮的方法是这样的:

export class Messages
{
    static CouldNotValidateRequest: string = 'There was an error validating the request';
    static PasswordMustNotBeBlank: string = 'Password must not be blank';   
}

import {Messages as msg} from '../core/messages';
console.log(msg.PasswordMustNotBeBlank);

enum e{
    hello = 1,
    somestr = 'world'
};

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

Typescript中的字符串枚举:

字符串枚举是一个类似的概念，但是有一些细微的运行时差异，如下文所述。在string enum中，每个成员必须用string字面值或另一个string enum成员常量初始化。

enum Direction {
  Up = "UP",
  Down = "DOWN",
  Left = "LEFT",
  Right = "RIGHT",
}

虽然字符串枚举没有自动递增的行为，但字符串枚举的好处是它们很好地“序列化”。换句话说，如果你正在调试并且必须读取一个数值enum的运行时值，这个值通常是不透明的——它本身没有传达任何有用的含义(尽管反向映射通常会有所帮助)，字符串enum允许你在代码运行时给出一个有意义且可读的值，与枚举成员本身的名称无关。 参考链接如下。

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 " 
}

我认为你应该试试这个，在这种情况下，变量的值不会改变，它的工作方式很像枚举，使用类也可以，唯一的缺点是你可以错误地改变静态变量的值这是我们不希望在枚举中发生的。

namespace portal {

export namespace storageNames {

    export const appRegistration = 'appRegistration';
    export const accessToken = 'access_token';

  }
}

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)
