Question

不确定是否有lodash或其他util方法来映射对象序列。在这种情况下，必须手动重新排序一堆嵌套对象的顺序。

//unprocessed
       {
           "order": [
          "home",
          "work"
        ],
        "questions": {
          "US": {
            "work": "working",
            "home": "driving home"
          },
          "UK": {
            "work": "go to work",
            "home": "go to home"
          }
        }
    }

如何基于订单的值映射问题对象的对象的答案。处理后的输出应该是

{
    "questions": {
      "US": {
        "home": "driving home",
        "work": "working"
      },
      "UK": {
        "home": "go to home",
        "work": "go to work"
      }
    }
}

Answer 1

“问题”：{ “美国”：{ “ work”：“工作”， “ home”：“开车回家” }， “英国”：{ “ work”：“上班”， “ home”：“回家” } } 是同样的 “问题”：{ “美国”：{ “ home”：“开车回家”， “工作”：“工作” }， “英国”：{ “ home”：“回家”， “工作”：“上班” } } 所以你什么都不做

Answer 2

如果您实际上要按顺序订购它，那么我希望您使用数组来存储住所和工作。

例如：

问题：{美国：['驾车回家'，'工作']}

Answer 3

我不明白为什么要订购键值对。但是我已经完成了一次打印。请参见下面的代码。

var data = { name:'stack',
             age:40, 
             grant:6000


};
console.log(Object.entries(data).sort(function(a, b) {<SORT LOGIC>}).reduce( (o,[k,v]) => (o[k]=v,o), {} ));

Answer 4

这里有一些代码可以按order数组中指定的顺序访问它们以显示它们。

const data = {"order": ["home","work"],"questions": {"US": {"work": "working","home": "driving home"},"UK": {"work": "go to work","home": "go to home"}}};

// using/accessing the data to display to client
const {order:orderedAccess, questions} = data;

Object.keys(questions).map(country=>
  orderedAccess.forEach(action=>console.log(country, action, questions[country][action]))
)

映射对象的对象以与数组序列匹配
