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" ];

Typescript游乐场示例

enum TransactionStatus {
  SUBMITTED = 'submitted',
  APPROVED = 'approved',
  PAID = 'paid',
  CANCELLED = 'cancelled',
  DECLINED = 'declined',
  PROCESSING = 'processing',
}


let set1 = Object.entries(TransactionStatus).filter(([,value]) => value === TransactionStatus.SUBMITTED || value === TransactionStatus.CANCELLED).map(([key,]) => {
    return key
})


let set2 = Object.entries(TransactionStatus).filter(([,value]) => value === TransactionStatus.PAID || value === TransactionStatus.APPROVED).map(([key,]) => {
    return key
})

let allKeys = Object.keys(TransactionStatus)



console.log({set1,set2,allKeys})

简单地说

如果你的枚举如下:

export enum Colors1 {
  Red = 1,
  Green = 2,
  Blue = 3
}

要获得特定的文本和值:

console.log(Colors1.Red); // 1 
console.log(Colors1[Colors1.Red]); // Red

获取值和文本列表:

public getTextAndValues(e: { [s: number]: string }) {
  for (const enumMember in e) {
    if (parseInt(enumMember, 10) >= 0) {
      console.log(e[enumMember]) // Value, such as 1,2,3
      console.log(parseInt(enumMember, 10)) // Text, such as Red,Green,Blue
    }
  }
}
this.getTextAndValues(Colors1)

如果你的枚举如下:

export enum Colors2 {
  Red = "Red",
  Green = "Green",
  Blue = "Blue"
}

要获得特定的文本和值:

console.log(Colors2.Red); // Red
console.log(Colors2["Red"]); // Red

获取值和文本列表:

public getTextAndValues(e: { [s: string]: string }) {
  for (const enumMember in e) {
    console.log(e[enumMember]);// Value, such as Red,Green,Blue
    console.log(enumMember); //  Text, such as Red,Green,Blue
  }
}
this.getTextAndValues(Colors2)

这对于基于键值的enum更有效:

enum yourEnum {
  ["First Key"] = "firstWordValue",
  ["Second Key"] = "secondWordValue"
}

Object.keys(yourEnum)[Object.values(yourEnum).findIndex(x => x === yourValue)]
// Result for passing values as yourValue
// FirstKey
// SecondKey

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);

如果你只搜索名称，然后迭代使用:

Object.keys(myEnum).map(key => myEnum[key]).filter(value => typeof value === 'string') as string[];
