在键值对的规范化对象中查找具有给定值的对象

Question

假设我有一个标准化对象（正如您在使用 redux 时经常看到的那样）包含如下键值对：

const normalized_object = {
  "1": {
    id: "1",
    color: "red",
    other_id: "45"
  },
  "2": {
    id: "2",
    color: "blue",
    other_id: "101"
  },
  "3": {
    id: "3",
    color: "green",
    other_id: "77"
  }
};

检索具有给定 other_id 的内部对象的最佳方法是什么。类似于以下内容：

const inner_obj = normalized_object.find(entry => entry.other_id === "77");
console.log(inner_obj);

// Prints the third inner object with id "3"

有单线的吗？

Answer 1

您可以使用 Object.values:

const normalized_object = {
  "1": { id: "1", color: "red", other_id: "45" },
  "2": { id: "2", color: "blue", other_id: "101" },
  "3": { id: "3", color: "green", other_id: "77" }
};

const inner_obj = Object.values(normalized_object).find(entry => entry.other_id === "77");

console.log(inner_obj);
