这里有很多答案，尽管这是一个7年前的问题，但我还是查了一下，我猜会有更多的答案出现在这里。这是我的解决方案，它比其他解决方案简单一点，它处理数字/文本/混合值枚举，都是一样的。

enum funky {
    yum , tum='tum', gum = 'jump', plum = 4
}

const list1 = Object.keys(funky)
  .filter(k => (Number(k).toString() === Number.NaN.toString()));
console.log(JSON.stringify(list1)); // ["yum","tum","gum","plum"]" 

 // for the numeric enum vals (like yum = 0, plum = 4), typescript adds val = key implicitly (0 = yum, 4 = plum)
 // hence we need to filter out such numeric keys (0 or 4)
 

要获得枚举值的列表，您必须使用:

enum AnimalEnum {
  DOG = "dog", 
  CAT = "cat", 
  MOUSE = "mouse"
}

Object.values(AnimalEnum);

在当前的TypeScript版本1.8.9中，我使用类型化enum:

export enum Option {
    OPTION1 = <any>'this is option 1',
    OPTION2 = <any>'this is option 2'
}

与结果在这个Javascript对象:

Option = {
    "OPTION1": "this is option 1",
    "OPTION2": "this is option 2",
    "this is option 1": "OPTION1",
    "this is option 2": "OPTION2"
}

所以我必须通过键和值查询，只返回值:

let optionNames: Array<any> = [];    
for (let enumValue in Option) {
    let optionNameLength = optionNames.length;

    if (optionNameLength === 0) {
        this.optionNames.push([enumValue, Option[enumValue]]);
    } else {
        if (this.optionNames[optionNameLength - 1][1] !== enumValue) {
            this.optionNames.push([enumValue, Option[enumValue]]);
        }
    }
}

我在数组中收到选项键:

optionNames = [ "OPTION1", "OPTION2" ];

可以是简短的:

enum AnimalEnum {
  DOG = "dog", 
  CAT = "cat", 
  MOUSE = "mouse"
}

Object.keys(AnimalEnum).filter(v => typeof v == 'string' && isNaN(v))

让ts-enum-util (github, npm)为您工作，并提供许多额外的类型安全实用程序。适用于字符串和数字enum，正确忽略数字enum的数字索引反向查找条目:

字符串枚举:

import {$enum} from "ts-enum-util";

enum Option {
    OPTION1 = 'this is option 1',
    OPTION2 = 'this is option 2'
}

// type: ("OPTION1" | "OPTION2")[]
// value: ["OPTION1", "OPTION2"]
const keys= $enum(Option).getKeys();

// type: Option[]
// value: ["this is option 1", "this is option 2"]
const values = $enum(Option).getValues();

数字枚举:

enum Option {
    OPTION1,
    OPTION2
}

// type: ("OPTION1" | "OPTION2")[]
// value: ["OPTION1", "OPTION2"]
const keys= $enum(Option).getKeys();

// type: Option[]
// value: [0, 1]
const values = $enum(Option).getValues();

如果你有enum

enum Diet {
  KETO = "Ketogenic",
  ATKINS = "Atkins",
  PALEO = "Paleo",
  DGAF = "Whatever"
}

然后你可以得到如下的键和值:

Object.keys(Diet).forEach((d: Diet) => {
  console.log(d); // KETO
  console.log(Diet[d]) // Ketogenic
});
