如何在javascript中将json对象转换为json数组

Question

The JSON object I have

{Yana: 1, Pirelli: 2, Good Year: 1}

Expected results

series: [
         {name: 'Yana', data: [1]},
         {name: 'Pirelli', data: [5]},
         {name: 'Good year', data: [5]}
        ]

Answer 1

Object.entries will help here

 var input = {"Yana": 1, "Pirelli": 2, "Good Year": 1}; var output = Object.entries(input).map(([name, v]) => ({name, data:[v]})); console.log (output);

Answer 2

How about this:

const object = {"Yana": 1, "Pirelli": 2, "Good Year": 1};

Object.keys(object).map(key => {
    return {name: key, data: [object[key]]};
})

Object.keys gets an array of the key names from object which can be iterated over using map . Using this it's then simple to construct the output array in your desired format.

Answer 3

You can use a forEach() in Object.keys() for data object:

 var data = {"Yana":1,"Pirelli":2,"Good Year":1}; var res = []; Object.keys(data).forEach(key => res.push({name: key, data:[data[key]]})); console.log(res);

Answer 4

The object you provided is not a valid JSON object. In JSON format your object would be:

{"Yana": 1, "Pirelli": 2, "Good Year": 1}

Assuming that you have that in a string, first thing you need to do is to parse it as JS object:

const jsonData = '{"Yana": 1, "Pirelli": 2, "Good Year": 1}'
const object = JSON.parse(jsonData);

// Now get all the keys from the object:
const brands = Object.keys(object);

// Finally, create a new object with the desired properties:
const result = brands.map(brand => {
  return {
    name: brand,
    data: object[brand]
  };
})
