具有已知属性的Typescript对象动态

Question

我遇到需要动态使用对象属性的情况。我不喜欢打字稿。.

情况与上述情况类似。

如何键入检查Enum[val]或foo变量？

enum Enum {
    VAR1 = "A",
    VAR2 = "B",
}

const foo = ["VAR1", "VAR2"];
foo.forEach(val => {
    const a = Enum[val]; // Typescript doesn't like it (val implicitly has 'any' type...)
    const b = Enum[val as any]; // This is "OK", but I use "any", which I'm trying to avoid.
});

Answer 1

const foo: (keyof typeof Enum)[] = ["VAR1", "VAR2"];
