另一种方法是使用ES8 Object.entries

export enum Weeks {  
    MONDAY = 1,  
    TUESDAY= 2,  
    WEDNESDAY = 3,  
    THURSDAY = 4,  
    FRIDAY = 5,  
    SATURDAY=6,  
    SUNDAY=7,  
}


function convertEnumToArray(){
   const arrayObjects = []            
     // Retrieve key and values using Object.entries() method. 
     for (const [propertyKey, propertyValue] of Object.entries(Weeks)) { 

      // Ignore keys that are not numbers
      if (!Number.isNaN(Number(propertyKey))) {  
        continue;  
      }  

      // Add keys and values to array
      arrayObjects.push({ id: propertyValue, name: propertyKey });  
    }        

  console.log(arrayObjects); 
}

将产生以下内容:

[ 
  { id: 1, name: 'MONDAY' },  
  { id: 2, name: 'TUESDAY' },  
  { id: 3, name: 'WEDNESDAY' },  
  { id: 4, name: 'THURSDAY' },  
  { id: 5, name: 'FRIDAY' },  
  { id: 6, name: 'SATURDAY' },  
  { id: 7, name: 'SUNDAY' } 
] 

无耻地从这个博客偷来的

枚举是运行时存在的真实对象。所以你可以这样反向映射:

let value = GoalProgressMeasurements.Not_Measured;
console.log(GoalProgressMeasurements[value]);
// => Not_Measured

基于此，您可以使用以下代码:

export enum GoalProgressMeasurements {
    Percentage = 1,
    Numeric_Target = 2,
    Completed_Tasks = 3,
    Average_Milestone_Progress = 4,
    Not_Measured = 5
}

let map: {id: number; name: string}[] = [];

for(var n in GoalProgressMeasurements) {
    if (typeof GoalProgressMeasurements[n] === 'number') {
        map.push({id: <any>GoalProgressMeasurements[n], name: n});
    }
}

console.log(map);

我很惊讶，在一个TypeScript线程中，没有人给出支持类型的有效TypeScript函数。下面是@user8363解决方案的变化:

const isStringNumber = (value: string) => isNaN(Number(value)) === false;

function enumToArray<T extends {}>(givenEnum: T) {
  return (Object.keys(givenEnum).filter(isStringNumber) as (keyof T)[]).map(
    (key) => givenEnum[key]
  );
}

由于具有字符串值的枚举不同于具有数字值的枚举，因此最好从@user8363解决方案中过滤非数字。

这里是你如何从enum字符串中获取值，数字混合:

/ /帮助 export const StringIsNotNumber = value => isNaN(Number(value)) === true; //将枚举转换为数组 导出函数enumToArray(枚举){ 返回种(enumme) .filter (StringIsNotNumber) .map(key => enumme[key]); ｝

设enum变量为:

 enum EnumName {
      A = 1,
      B = 2
    };

那么列表是:

const list = Object.keys(Enum)
.filter((value => isNaN(Number(value)) === false))
      .map(key => ({ id: key, value: Enum[key] }));

list的值为

list = [ 
{ id:1 , value: A },
{ id:2 , value: B },
];

我已经解出来了。 假设您有一个如下所示的枚举

export enum UnitEnum {
  GRAM = 'gm',
  KILOGRAM = 'kg',
  LITRE = 'lt',
  CENTIMETER = 'cm',
  INCH = 'in',
  METER = 'mt',
  KILOMETER = 'km',
}

你有这样一门课，

export interface Unit {
  Name: string;
  Symbol: string;
}

然后，您可以创建一个如下所示的函数，将异构枚举映射到某个类型的对象，

export function getDefaultUnits() {
  const myUnits = Object.entries(UnitEnum).map(x => {
    return { Name: x[0], Symbol: x[1] } as Unit
  })

  console.log(myUnits);

  return myUnits;
}
