export function enumKeys(E: any): string[] {
    return Object.keys(E).filter(k => isNaN(Number(k)));
}

export function enumValues(E: any): string[] | number[] {
    return enumKeys(E).map(k => E[k as any]);
}

两者都适用:

enum TestA {
    RED = "red",
    BLUE = "blue"
}

enum TestB {
    ONE = 1,
    TWO = 2
}

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;
}

我从几个月前就了解了typescript，下面的解决方案对我来说很有效。希望它也能帮助到一些人

export enum ScheduleType {
  Basic = <any>'B',
  Consolidated = <any>'C',
}

scheduleTypes = Object.keys(ScheduleType)
.filter((k, i) => i % 2)
.map((key: any) => {
  return {
    systemValue: key,
    displayValue: ScheduleType[key],
  };
});

它给出了如下的结果- [{displayValue: "Basic"， systemValue: "B"}， {displayValue: "Consolidated"， systemValue: "C"}]

enum目标进度测量{ 百分比= 1， Numeric_Target = 2， Completed_Tasks = 3， average_milestone one_progress = 4， Not_Measured = 5 ｝ Const数组= [] for (const [key, value] of Object.entries(GoalProgressMeasurements)) { if (!Number. isnan (Number(key)) { 继续; ｝ 数组中。Push ({id:值，名称:键。Replace ('_'， ")}); ｝ console.log(数组);

我使用

Object.entries(GoalProgressMeasurement).filter(e => !isNaN(e[0]as any)).map(e => ({ name: e[1], id: e[0] }));

一条简单的线就可以做到这一点。

它只需要3个简单的步骤 -使用Object.entries加载键和值的组合。 -过滤掉非数字(因为typescript会为反向查找生成值)。 -然后我们将它映射到我们喜欢的数组对象。

你可以这样做:

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

export class GoalProgressMeasurement {
    constructor(public goalProgressMeasurement: GoalProgressMeasurements, public name: string) {
    }
}

export var goalProgressMeasurements: { [key: number]: GoalProgressMeasurement } = {
    1: new GoalProgressMeasurement(GoalProgressMeasurements.Percentage, "Percentage"),
    2: new GoalProgressMeasurement(GoalProgressMeasurements.Numeric_Target, "Numeric Target"),
    3: new GoalProgressMeasurement(GoalProgressMeasurements.Completed_Tasks, "Completed Tasks"),
    4: new GoalProgressMeasurement(GoalProgressMeasurements.Average_Milestone_Progress, "Average Milestone Progress"),
    5: new GoalProgressMeasurement(GoalProgressMeasurements.Not_Measured, "Not Measured"),
}

你可以这样使用它:

var gpm: GoalProgressMeasurement = goalProgressMeasurements[GoalProgressMeasurements.Percentage];
var gpmName: string = gpm.name;

var myProgressId: number = 1; // the value can come out of drop down selected value or from back-end , so you can imagine the way of using
var gpm2: GoalProgressMeasurement = goalProgressMeasurements[myProgressId];
var gpmName: string = gpm.name;

您可以根据需要使用对象的附加属性扩展GoalProgressMeasurement。我将这种方法用于每个应该是包含多个值的对象的枚举。
