Question

Currencies.js

Verbose

Test.js

Install-Package FSharp.Core -Version X

index.js

var Currency = {};
Currency["USA"] = "dollar";
Currency["INDIA"] = "rupee";
Currency["CHINA"] = "yuan";

export { Currency };

问题出在import { Currency } from './currencies'; export { Currency.USA as USA }; // wrong export { Currency.CHINA as CHINA }; // wrong export { Currency.INDIA as INDIA }; // wrong。我用于命名导出的语法是错误的。有人可以纠正吗？如何从其他位置导入对象时单独导出对象值。

Answer 1

嗯，这太琐碎了

＃1方法：

const Currency = {
  USA: 'dollar',
  INDIA: 'rupee',
  CHINA: 'yuan'
}
export const { USA, INDIA, CHINA } = Currency;

＃2方法（与＃1相同）

export const { USA, INDIA, CHINA } = {
  USA: 'dollar',
  INDIA: 'rupee',
  CHINA: 'yuan'
};

＃3方法：

export const USA = 'dollar';
export const INDIA = 'rupee';
export const CHINA = 'yuan';

您可以像使用（所有方法）一样使用它：

import {USA} form './Currencies'

如何将枚举值导出为单个命名导出？
