  12: "Editor"

}

这是我的数组

array1 = ["Reader", "Author"]

Answer 1

你可以 filter对象的键并使用 includes 检查键是否在数组中有值

const object1 = {
  1: "Reader",
  8: "Author",
  3: "Publisher",
  9: "Site Editor",
  11: "Guest",
  12: "Editor",
  13: "Designer",
  14: "Publicist"
};

const array1 = ["Reader", "Author"]

const keys = Object.keys(object1).filter(k => array1.includes(object1[k]))

console.log(keys)
