JavaScript对象将对象键移动到值阵列

Question

如何将键传输到作为对象的值。 我想将产品 ID 级别的键移动到“id”值

我有一个像这样的数组：

const products = [
  {
    "2": {
      "name": "Name of product with id 2",
      "ean": "123123123",
      "parameters": []
      },
    "3": {
      "name": "Name of product with id 3",
      "ean": "123123122",
      "parameters": []
      },
    "5": {
      "name": "Name of product with id 5",
      "ean": "123123121",
      "parameters": []
      }
  }
]

我期待这样：

[
  {
    "id": "2",
    "name": "Name of product with id 2",
    "ean": "123123123",
    "parameters": []
  },
  {
    "id": "3",
    "name": "Name of product with id 3",
    "ean": "123123122",
    "parameters": []
  },
  {
    "id": "5",
    "name": "Name of product with id 5",
    "ean": "123123121",
    "parameters": []
  }
]

Answer 1

• 使用 > and ，
• 使用 数组＃映射 ，在上面迭代，然后将 id 添加到其他属性

const products = [
  {
    "2": { "name": "Name of product with id 2", "ean": "123123123", "parameters": [] },
    "3": { "name": "Name of product with id 3", "ean": "123123122", "parameters": [] },
    "5": { "name": "Name of product with id 5", "ean": "123123121", "parameters": [] }
  }
];

const res = products
  .flatMap(Object.entries)
  .map(([ id, props ]) => ({ ...props, id }));

console.log(res);

Answer 2

您只需使用与 array。 map（）方法。

演示：

const products = [
  {
    "2": {
      "name": "Name of product with id 2",
      "ean": "123123123",
      "parameters": []
      },
    "3": {
      "name": "Name of product with id 3",
      "ean": "123123122",
      "parameters": []
      },
    "5": {
      "name": "Name of product with id 5",
      "ean": "123123121",
      "parameters": []
      }
  }
];

const res = Object.keys(products[0]).map((id) => {
    products[0][id]['id'] = id;
  return products[0][id];
});

console.log(res);
