Question

我有这个JSON输出：

[{"id":"15","title":"music"},{"id":"103","title":"movie"},{"id":"214","title":"book"}]

如何将其转换为Javascript中的数组：

items = array(
     15 => 'music',
     103 => 'movie',
     214 => 'book'
          );

Answer 1

您可以将Object.assign用于破坏对象并构建新对象。

＆＃13;

var array = [{ id: "15", title: "music" }, { id: "103", title: "movie" }, { id:"214", title: "book" }],
    object = Object.assign(...array.map(({ id, title }) => ({ [id]: title })));
    
console.log(object);

＆＃13;

Answer 2

您可以使用reduce(...)：

var arr = [{"id":"15","title":"music"},{"id":"103","title":"movie"},{"id":"214","title":"book"}];
var obj = arr.reduce((acc, o) => { acc[o.id] = o.title; return acc; }, {});
console.log(obj);
// prints: {15: "music", 103: "movie", 214: "book"}

Answer 3

似乎你在寻找像这样的对象

var x = [{
  "id": "15",
  "title": "music"
}, {
  "id": "103",
  "title": "movie"
}, {
  "id": "214",
  "title": "book"
}];
let temp = {};
x.forEach(function(item) {
  temp[item.id] = item.title
})
console.log(temp)
