javascript - 如何更改 Json 格式，例如值将是对象名称

Question

如何从以下形式设置 json 文件:我喜欢将 id 值设置为对象名称。

[{
  "id": 1,
  "public_name": "Duygu D.",
  "professions": "Kumas dizayn",
  "job_preference": "freelancer"
}, {
  "id": 2,
  "public_name": "Meral A.",
  "professions": "Model Uyg.",
  "job_preference": "freelancer"
}]

到下面的表格:

{
  "1": {
    "public_name": "Duygu D.",
    "professions": "Kumas dizayn",
  },
  "2": {
    "public_name": "Meral A.",
    "professions": "Model Uyg.",
  }
}

Answer 1

您可以使用数组的 reduce()方法。

var arr = [{
  "id": 1,
  "public_name": "Duygu D.",
  "professions": "Kumas dizayn",
  "job_preference": "freelancer"
}, {
  "id": 2,
  "public_name": "Meral A.",
  "professions": "Model Uyg.",
  "job_preference": "freelancer"
}];

var obj = arr.reduce(function(o, v, i) {
  o[v.id] = {"public_name":v.public_name,  "professions": v.professions};
  return o;
}, {});
