我如何将 json 对象作为 json 数组

Question

I've a json returned as part of my api call and it looks like below.

{
  'D1': {
    'name': 'Emp1',
    'Age':22
  },
  'D2': {
    'name': 'Emp2',
    'Age':43
  },
};

I want to convert this into an array. ie in the below format.

[
  'D1': {
    'name': 'Emp1',
    'Age':22
  },
  'D2': {
    'name': 'Emp2',
    'Age':43
  },
];

I'm trying to do it using the below code.

 let obj = { 'D1': { 'name': 'Emp1', 'Age':22 }, 'D2': { 'name': 'Emp2', 'Age':43 }, }; let wholeArray = Object.keys(obj).map(key => obj[key]); console.log(wholeArray);

But it is stripping off the outer JSON keys.

please let me know where am I going wrong and how to get the expected output.

Answer 1

You could separate the object into an array with only one key/value pair.

 let object = { D1: { name: 'Emp1', Age:22 }, D2: { name: 'Emp2', Age:43 } }, array = Object .entries(object) .map(pair => Object.fromEntries([pair])); console.log(array);

 .as-console-wrapper { max-height: 100% !important; top: 0; }

Answer 2

This:

 [ 'D1': { 'name': 'Emp1', 'Age':22 }, 'D2': { 'name': 'Emp2', 'Age':43 }, ];

Simply does not exist. Arrays have no keys, objects do.

The most you could do is:

[
  {
    'D1': {
      'name': 'Emp1',
      'Age':22
    }
  },{
    'D2': {
      'name': 'Emp2',
      'Age':43
    }
  }
];

An array of objects with a single key.

One code variant for doing this:

 let obj = { 'D1': { 'name': 'Emp1', 'Age':22 }, 'D2': { 'name': 'Emp2', 'Age':43 }, }; //let wholeArray = Object.keys(obj).map(key => obj[key]); let wholeArray = Object.keys(obj).map(key => { let ret={}; ret[key]=obj[key]; return ret; }); console.log(wholeArray);

Side remark: I see a lot of similar question in the past 2-3 days, people want "JSON array" with keys, and they also carefully put an "empty" comma at the end of their arrays. Are you guys coming from some course?
