带有打字稿的枚举

Question

我有这个带有枚举的明显简单的代码部分。

这些是类型定义：

export enum AcquisitionStatus {
  IDLE, RUNNING, DONE, ERROR,
}

export type State = {
  acquisitionCycleStatus: {
    progress: number
    status: keyof typeof AcquisitionStatus
  }
}

这是我使用它们的功能：

const initialState = {
  acquisitionCycleStatus: {
    progress: 0,
    status: AcquisitionStatus.IDLE,
  },
}

const StoreContext = createContext<[State, Dispatch<Actions>]>([
  initialState,
  () => null,
])

这是在initialState 上报告 Typescript 的错误。

Type ‘{ acquisitionCycleStatus: { progress: number; status: AcquisitionStatus; }; }’ is not assignable to type ‘State’.
  The types of ‘acquisitionCycleStatus.status’ are incompatible between these types.
    Type ‘AcquisitionStatus’ is not assignable to type ‘“IDLE” | “RUNNING” | “DONE” | “ERROR”’.

我做错了什么？有人可以帮助我吗？谢谢。

Answer 1

枚举的值类似于 0,1,2,3 你需要告诉枚举他们的值。

试试

export enum AcquisitionStatus {
  IDLE = 'IDLE',
  RUNNING = 'RUNNING',
  DONE = 'DONE',
  ERROR = 'ERROR',
}
