javascript - 如何从 json 数组中删除名称字段？

Question

我有一个像这样的 json 数组:

(3) [{…}, {…}, {…}]
0: {Id: 1, Name: "bask"}
1: {Id: 2, Name: "voll"}
2: {Id: 3, Name: "badminton"} 

我想把它变成这样:

{1:"bask",2:"voll",3:"badminton"}

Answer 1

您可以使用reduce循环遍历数组并构建所需键/值对的对象

let data = [{Id: 1, Name: "bask"},{Id: 2, Name: "voll"},{Id: 3, Name: "badminton"}]

let output = data.reduce((op, {Id, Name}) => {
  op[Id] = Name
  return op
},{})

console.log(output)
