Javascript对象将对象键移动到值数组中

Question

如何将键传递到作为对象的值。我想将作为产品ID级别的键向下移动到值"0"；id"；

我有一个这样的数组：

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": []
}
}
]

我期待这个：

[
{
"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Array#flatMap和Object#entries，获取id对象对列表
• 使用Array#map，迭代上述属性，并将id添加到其他属性中

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

您可以简单地通过使用Object.keys((和Array.map((方法来实现这一点。

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);
