[英]Is it possible to use enum's values as value for object key in type declaration?
I have enum HealthPlanStatus which was generated by enum HealthPlanStatus .我有枚举 HealthPlanStatus ,它是由枚举 HealthPlanStatus生成的。 In the end I would like to use enum's keys and values to generate not only status keys for type IHealthPlanResponse but also a title value as enum's values.
最后,我想使用枚举的键和值不仅为类型 IHealthPlanResponse生成状态键,而且还生成标题值作为枚举的值。
export enum HealthPlanStatus {
Todo = 'To-Do',
InProgress = 'Working on it',
}
export type IHealthPlanResponse = {
[status in keyof typeof HealthPlanStatus]: {
title: string;
};
};
It gives me strict structure where I have a status key as enum's key ( Todo, InProgress ...):它给了我严格的结构,其中我有一个状态键作为枚举的键( Todo、InProgress ...):
type IHealthPlanResponse = {
readonly Todo: {
title: string;
};
readonly InProgress: {
title: string;
};
}
Also I would like to have a title type as enum's values.我也想有一个标题类型作为枚举的值。 For example:
例如:
type IHealthPlanResponse = {
readonly Todo: {
title: 'To-Do';
};
readonly InProgress: {
title: 'Working on it';
};
}
Does this work for you?这对你有用吗?
export enum HealthPlanStatus {
Todo = 'To-Do',
InProgress = 'Working on it',
}
export type IHealthPlanResponse = {
readonly [status in keyof typeof HealthPlanStatus]: {
title: (typeof HealthPlanStatus)[status];
};
};
let t: IHealthPlanResponse = {} as any
const status = t.InProgress.title // -> HealthPlanStatus.InProgress
If you don't like to see the enum 'key' here and want to have the string
literal as a type you can change it to this:如果您不想在此处看到枚举“键”并希望将
string
文字作为一种类型,您可以将其更改为:
export type IHealthPlanResponse = {
readonly [status in keyof typeof HealthPlanStatus]: {
title: `${(typeof HealthPlanStatus)[status]}`;
};
};
let t: IHealthPlanResponse = {} as any
const status = t.InProgress.title // -> 'Working on it'
