javascript - 在 javascript 中重建包含嵌套数组的对象数组

Question

我正在努力解决这里的问题。 假设我有一个像这样的对象数组:

[
 {name:Alex, products: [{type: 1, code: 1213}, {type: 2, code: 2312}]},
 {name:Alex, products: [{type: 1, code: 1213}, {type: 2, code: 2312}]}
]

我想以某种方式将我的对象重建为如下所示:

[
 {name:Alex, products: [{name:Alex, type: 1, code: 1213}, {name:Alex, type: 2, code: 2312}]},
 {name:Alex, products: [{{name:Alex, type: 1, code: 1213}, {{name:Alex, type: 2, code: 2312}]}
]

因此每个嵌套数组都包含名称。这在 JavaScript 中可能吗？

Answer 1

您可以在对象中使用带有扩展语法的map()方法来创建包含更新对象的新数组并保留原始数据。

const data = [
 {name:'Alex', products: [{type: 1, code: 1213}, {type: 2, code: 2312}]},
 {name:'Alex', products: [{type: 1, code: 1213}, {type: 2, code: 2312}]}
]

const result = data.map(e => ({
  ...e,
  products: e.products.map(p => {
    return {...p, name: e.name}
  })
}))

console.log(result)
