遍历对象中的特定索引

Question

我有一个看起来像这样的对象

const userAnswers = { 
  1: {id: 3, value: "Assistant manager"},
  2: {id: 1, value: "I am the primary decision maker"},
  3: {
    1: {id: 1, name: "Water quality management", value: "On a long list of priorities", valueId: 2},
    2: {id: 2, name: "Greenhouse gas reduction", value: "On a long list of priorities", valueId: 2},
    3: {id: 3, name: "Finanicial management", value: "On a long list of priorities", valueId: 2},
    4: {id: 4, name: "Feed management", value: "On a long list of priorities", valueId: 2}
  }
}

我知道我可以以此遍历整个对象

Object.values(answers).forEach(value => { console.log(value)} )

但是是否只想遍历3:内部的嵌套对象？

编辑：我的console.log

Answer 1

您可以尝试

Object.values(Object.values(object1)[2]).forEach(item => console.log(item));

Answer 2

就像我在评论中说的那样，您可以遍历userAnswers['3']的值，并通过方括号（object["keyName"]）对其进行访问

const userAnswers = { 
  1: {id: 3, value: "Assistant manager"},
  2: {id: 1, value: "I am the primary decision maker"},
  3: {
    1: {id: 1, name: "Water quality management", value: "On a long list of priorities", valueId: 2},
    2: {id: 2, name: "Greenhouse gas reduction", value: "On a long list of priorities", valueId: 2},
    3: {id: 3, name: "Finanicial management", value: "On a long list of priorities", valueId: 2},
    4: {id: 4, name: "Feed management", value: "On a long list of priorities", valueId: 2}
  }
}

var objectWithKey3 = userAnswers['3']

for (var obj of Object.values(objectWithKey3)){
  console.log(obj)
}
