通过javascript中的对象键名称修改/更改对象键数组

Question

我想知道如何在javascript中使用对象键修改对象键数组。

我有数组对象arrobj和对象obj ，我想在 javascript 中使用对象键更改数组对象键，即更改数组对象键name, amt使用对象键topic and price更改name, amt

let obj={
   status: 1, data:{
   config:{
   topic: "xx", price: "100"}
   }
  }

let arrobj ={
  status:1,
  data: [
    {
      id:1,
      name: "abc",
      amt: "50",
      city: "TH"
    },
    {
      id:2,
      name: "zen",
      amt: "100",
      city: "IN"
    },
  ]
}

var result = arrobj.data.map(e=>{
   var tt = obj.data.config
  return Object.keys(tt).forEach(i=>{
    return {
      i:e.name
     }
   })
})


Expected Output

 [
    {
      id:1,
      topic: "abc",
      price: "50",
      city: "TH"
    },
    {
      id:2,
      topic: "zen",
      price: "100",
      city: "IN"
    },
  ]

Answer 1

在这里，我们将新键添加到第一个映射中的数组中，然后删除第二个映射中的旧键

 let arrobj = { status: 1, data: [{ id: 1, name: "abc", amt: "50", city: "TH" }, { id: 2, name: "zen", amt: "100", city: "IN" }, ] } arrobj.data = arrobj.data.map(e => ({ ...e, topic: e.name, price: e.amt })) .map(e => { delete e.amt; delete e.name; return e }) console.log(arrobj)

Answer 2

 let obj={ status: 1, data:{ config:{ topic: "xx", price: "100"} } } let arrobj ={ status:1, data: [ { id:1, name: "abc", amt: "50", city: "TH" }, { id:2, name: "zen", amt: "100", city: "IN" }, ] } var result = arrobj.data = arrobj.data.map(paylaod => { let {amt, name, ...rest} = paylaod return { ...rest, topic: paylaod.name, price: paylaod.amt } }) arrobj.data = result; console.log(arrobj);
