枚举：类型的参数＆＃x27;＆quort; hh：mm＆quot＆quot＆＃x27;不能分配给类型的参数。

我做出了一个接受两个参数数据和格式的函数。我正在尝试为称为“格式”的参数制作枚举（格式化）。但是，这是一个错误：

类型'“ HH：MM”'的参数不能分配给类型的参数 “格式化”

如何为第二个参数编写正确的枚举？ Here is Playground on TypeScript Click

Code ：

const basicTime: any = {
  year: 'numeric',
  month: 'short',
  day: '2-digit',
  hour: 'numeric',
  minute: 'numeric',
};

const hoursMinutes: any = {
  hour: 'numeric',
  minute: 'numeric',
};

enum FormatOptions {
  HoursMinutes = 'HH:MM',
  MonthDayYear = 'MM/DD/YYYY',
};

const dateFormat = (date: Date, format: FormatOptions) => {
  if (format === 'HH:MM') {
    return new Date(date).toLocaleString('en-US', hoursMinutes);
  }

  return new Date(date).toLocaleString('en-US', basicTime);
};

dateFormat(new Date, 'HH:MM');

I made a function that accepts two arguments data and format. I'm trying to make ENUM(FormatOptions) for argument called "format". However, here is an error:

Argument of type '"HH:MM"' is not assignable to parameter of type
'FormatOptions'

How to write the correct ENUM for 2nd argument?

const basicTime: any = {

  month: 'short',
  day: '2-digit',
  hour: 'numeric',

const hoursMinutes: any = {
  hour: 'numeric',
  minute: 'numeric',
};

enum FormatOptions {
  HoursMinutes = 'HH:MM',
  MonthDayYear = 'MM/DD/YYYY',
};

const dateFormat = (date: Date, format: FormatOptions) => {
  if (format === 'HH:MM') {
    return new Date(date).toLocaleString('en-US', hoursMinutes);

  return new Date(date).toLocaleString('en-US', basicTime);
};

dateFormat(new Date, 'HH:MM');

而不是enum您可以使用Union：

const basicTime: Intl.DateTimeFormatOptions = {
  year: 'numeric',
  month: 'short',
  day: '2-digit',
  hour: 'numeric',
  minute: 'numeric',
};

const hoursMinutes: Intl.DateTimeFormatOptions = {
  hour: 'numeric',
  minute: 'numeric',
};


type FormatOptions = 'HH:MM' | 'MM/DD/YYYY'


const dateFormat = (date: Date, format: FormatOptions) => {
  if (format === 'HH:MM') {
    return new Date(date).toLocaleString('en-US', hoursMinutes);
  }

  return new Date(date).toLocaleString('en-US', basicTime);
};

dateFormat(new Date(), 'HH:MM');

Instead of enum you can use union:

const basicTime: Intl.DateTimeFormatOptions = {
  year: 'numeric',
  month: 'short',
  day: '2-digit',
  hour: 'numeric',
  minute: 'numeric',
};

const hoursMinutes: Intl.DateTimeFormatOptions = {
  hour: 'numeric',
  minute: 'numeric',
};


type FormatOptions = 'HH:MM' | 'MM/DD/YYYY'


const dateFormat = (date: Date, format: FormatOptions) => {
  if (format === 'HH:MM') {
    return new Date(date).toLocaleString('en-US', hoursMinutes);
  }

  return new Date(date).toLocaleString('en-US', basicTime);
};

dateFormat(new Date(), 'HH:MM');
