在不对内部对象的每个键使用 Object.entries() 的情况下循环遍历对象

Question

我想知道如何在不指定键的情况下循环遍历嵌套对象。我的意思是只取对象的名称来执行循环。有什么方法可以实现吗？您可以在底部看到我尝试过的内容。它确实有效，但我想知道是否有一种方法可以做到这一点而无需提及 keys(hero, monster)

要循环的对象：

const characterData = {
  hero: {
    name: "Wizard",
    avatar: "images/wizard.png",
    health: 60,
    diceCount: 3,
    currentDiceScore: []
  },
  monster: {
    name: "Orc",
    avatar: "images/orc.png",
    health: 10,
    diceCount: 1,
    currentDiceScore: []
  },
};

Object.entries(characterData.hero).forEach(([key, value]) => {
  console.log(`${key}: ${value}`)
});

Answer 1

您可以先遍历 Object.values() which, in this case, are the nested objects hero, monster and so on.. using Array.prototype.forEach(), and then your code that iterates over Object.entries() again using Array.prototype.forEach()

但是请注意，在 callbackFn 函数中使用了 方括号 Destructuring assignment and inside the console.log() Template literals (Template strings):

const characterData = {hero: {name: "Wizard",avatar: "images/wizard.png",health: 60,diceCount: 3,currentDiceScore: []},monster: {name: "Orc",avatar: "images/orc.png",health: 10,diceCount: 1,currentDiceScore: []},}

Object.values(characterData)
  .forEach(o => 
    Object.entries(o)
      .forEach(([k, v]) => 
        console.log(`${k}: ${v}`)))
