Question

让我说我有一个像这样的数组：

[ { full_name: 'Sickö' }, 
  { location: 'New York City, United States' },
  { follower: '1.2M' },
  { er: '5.59%' },
  { topics: 'Fashion' } ]

我想将其作为一个对象，例如：

{
  fullname: 'Sicko',
  location: 'New York City, United State'
  ..and more
}

我知道我可以使用Object.assign组合它们，但不知道如何分配所有它们。

Answer 1

let all = [ { full_name: 'Sickö' }, 
  { location: 'New York City, United States' },
  { follower: '1.2M' },
  { er: '5.59%' },
  { topics: 'Fashion' } ];

let res = Object.assign({}, ...all);

Answer 2

您可以使用Array.reduce()并从等于空对象{}的累加器开始，并在化简器的每次迭代中使用Object.assign()。像这样：

const input = [
  {full_name: 'Sickö'},
  {location: 'New York City, United States'},
  {follower: '1.2M'},
  {er: '5.59%'},
  {topics: 'Fashion'}
];

function assign(acc, obj)
{
    return Object.assign(acc, obj);
}

let res = input.reduce(assign, {});
console.log(res);

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

但是，Object.assign()旨在接受多个sources，因此，如果您有ES6支持，则可以将其与spread syntax一起使用：

const input = [
  {full_name: 'Sickö'},
  {location: 'New York City, United States'},
  {follower: '1.2M'},
  {er: '5.59%'},
  {topics: 'Fashion'}
];

let res = Object.assign({}, ...input);
console.log(res);

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

Answer 3

在标记jquery时，以防您需要使用相同的解决方案：

var data = [ { full_name: 'Sickö' }, 
  { location: 'New York City, United States' },
  { follower: '1.2M' },
  { er: '5.59%' },
  { topics: 'Fashion' } ];

var d = $.extend({}, ...data);

console.log(d);

如何分配数组中的所有对象？
