javascript - 遍历枚举，将枚举元素指定为参数

Question

我想迭代一个枚举。当我遍历这个枚举时，我得到了键和值，但我只想使用键将技能实例添加到技能数组。

enum eSkills {
    ACROBATICS = <any>"Acrobatics",
    APPRAISE = <any>"Appraise",
    BLUFF = <any>"Bluff",
    CLIMB = <any>"Climb",
    CRAFT = <any>"Craft"
}

class Skill {
    constructor(name: eSkills) {
        this.name = name;
    }

    name: eSkills;
}

let skills: Skill[] = [];

for (let skill in eSkills) {
    //TODO create new instance of Skill and push to skills array
}

我需要枚举的反向映射。

Answer 1

我猜你已经试过了，但没有用:

skills.push(new Skill(skill)); // Error: Argument of type 'string' is not assignable to parameter of type 'eSkills'.

您可以使用 type assertion 来解决这个问题(作为 eSkills):

skills.push(new Skill(skill as eSkills));
