将函数参数作为静态类的键

Question

class Example {
    static alpha () {
        return 'a'
    }
    static beta () {
        return 'a'
    }
    static get = <T extends keyof Example> (...keys: T[]) => _.pick(Fragments, keys)
}

Example.get('alpha', 'beta') // {alpha, beta}

我怎么有一个get方法来使用示例的键？

Answer 1

缺少typeof

class Example {
    static alpha () {
        return 'a'
    }
    static beta () {
        return 'a'
    }
    static get = <T extends keyof typeof Example> (...keys: T[]) => _.pick(Fragments, keys)
}

Example.get('alpha', 'beta') // {alpha, beta}
