Question

从本质上讲，这就是我的API中的有效负载的样子。我想重塑数据，以便可以在前端动态显示数据而无需对列名之类的内容进行硬编码。对于我值得使用的是DRF，axios和react-redux。话虽如此，我想我只需要学习更多香草js：/

*故意在一个条目中具有与另一个条目不同的键数。

data =[
{
    "id": 1,
    "j_column": {
        "name": "James",
        "outside_id": 1,
        "alt_name": "Jim",
        "full_name": "James the third"
    }
},
{
    "id": 3,
    "j_column": {
        "name": "Dennis",
        "outside_id": 57,
        "alt_name": "Denny",
        "full_name": "Dennis the third",
        "nickname": "Denny the super star"
    }
}]



newData =[
{
    "id": 1,
    "name": "James",
    "outside_id": 1,
    "alt_name": "Jim",
    "full_name": "James the third"
},
{
    "id": 3,
    "name": "Dennis",
    "outside_id": 57,
    "alt_name": "Denny",
    "full_name": "Dennis the third",
    "nickname": "Denny the super star"
}]

Answer 1

这是一种实现方法：

const data =[
  {
      "id": 1,
      "j_column": {
          "name": "James",
          "outside_id": 1,
          "alt_name": "Jim",
          "full_name": "James the third"
      }
  },
  {
      "id": 3,
      "j_column": {
          "name": "Dennis",
          "outside_id": 57,
          "alt_name": "Denny",
          "full_name": "Dennis the third",
          "nickname": "Denny the super star"
      }
}];

const newData = data.map((el) => {
  const obj = {...el.j_column};
  obj.id = el.id;
  return obj;
});

console.log(newData);

Answer 2

var new_data = [];
data.map(item => {
    var obj = {};
    Object.keys(item).map(itemKey => {
        if (typeof item[itemKey] !== 'object') {
            obj[itemKey] = item[itemKey]
        }else
            Object.keys(item[itemKey]).map(subItemKey => {
                obj[subItemKey] = item[itemKey][subItemKey]
            })
    })
    new_data.push(obj);
})
console.log(new_data);
