请教个 ts 中 enum 的问题？

Question

以下写法会报错

enum Abc {
  A = 'a',
  B = 'b',
  C = 'c',
}

// 只需要 A和B 这种情况应该怎么写呢
const map: Record<Abc, string> = {
  [Abc.A]: 'aaa',
  [Abc.B]: 'bbb',
}

Answer 1

Record<Exclude<Abc, 'c'>, string>

Answer 2

Record<Exclude<Abc, 'c'>, string>

Answer 3

enum Abc {
  A = 'a',
  B = 'b',
  C = 'c',
}

type AbcKeys = keyof typeof Abc;
type MyKeys = Exclude<AbcKeys, 'C'>;
// 或者 type MyKeys = Extract<AbcKeys, 'A' | 'B'>;  更符合你只想要A和B的意思

const map1: Record<typeof Abc[MyKeys], string> = {
    [Abc.A]: 'aaa',
    [Abc.B]: 'bbb',
};

Answer 4

enum Abc {
  A = 'a',
  B = 'b',
  C = 'c',
}

//使用 Abc.A | Abc.B  简单明了
const map: Record<Abc.A | Abc.B, string> = {
  [Abc.A]: 'aaa',
  [Abc.B]: 'bbb',  
}

Answer 5

const map: Record<string，string>
