在打字稿枚举中使用对象 [英] use object in typescript enum

问题描述

我有一个枚举:

 export enum PizzaSize {
          SMALL =  0,
          MEDIUM = 1,
          LARGE = 2

    }

但是在这里我想使用一些值对:例如小我想说的是，它有2个值(0、100).我该怎么办?

But here I would like to use some pair of values: e.g. SMALL i would like to say that it has 2 values (0, 100). How can I do this one?

我努力使用

export enum PizzaSize {
          SMALL =  {key:key, value: value},
         ...

    }

但是打字稿不接受这一点.

But typescript doesn't accept this one.

推荐答案

更新:在下面找到 @Javarome的答案，其中更优雅.我建议用他的方式.

如果需要使用Type，请尝试添加一些代码. 用法:getPizzSizeSpec(PizzaSize.small).value

Update: find @Javarome's answer below, which is more elegant. I suggest using his way.

If you need to use Type, try adding some code. usage: getPizzSizeSpec(PizzaSize.small).value

enum PizzaSize {
    small,
    medium,
    large
}
interface PizzaSizeSpec {
    key: number,
    value: number
}
function getPizzaSizeSpec(pizzaSize: PizzaSize): PizzaSizeSpec {
    switch (pizzaSize) {
        case PizzaSize.small:
            return {key:0, value: 25};
        case PizzaSize.medium:
            return {key:0, value: 35};
        case PizzaSize.large:
            return {key:0, value: 50};
    }
}
