Javascript：從 object 的嵌套數組中獲取值並使其成為 object 鍵

Question

我有一個這樣的數組 object

{
  "data": [{
    "location": {
      "type": "Point",
      "coordinates": [
        77.361916,
        28.606075
      ]
    },
  }]
}

我想從中獲取緯度和經度並將 object 變為如下所示：

{
  "data": [{
    "latitude": 28.606075,
    "longitude": 77.361916,
  }]
}

我怎樣才能做到這一點？ 我試着做

response.map((data: any) => {
  console.log(data.location);
  let latitude = data.location.coordinates[2];
  let longitude = data.location.coordinates[1];
  delete data.location;
  data.latitude = latitude;
  data.longitude = longitude;
})

我知道這是錯誤的，但我該如何解決呢？

Answer 1

如果你只有一套

 const oldObj = { "data": [{ "location": { "type": "Point", "coordinates": [ 77.361916, 28.606075 ] }, }] } const [longitude, latitude] = [...oldObj.data[0].location.coordinates] const newObj = { data: [{ latitude, longitude }] } console.log(newObj)

 const oldArr = [{ "data": [{ "location": { "type": "Point", "coordinates": [ 77.361916, 28.606075 ] }, }] }, { "data": [{ "location": { "type": "Point", "coordinates": [ 77.361916, 28.606075 ] }, }] }, { "data": [{ "location": { "type": "Point", "coordinates": [ 77.361916, 28.606075 ] }, }] } ] const newArr = oldArr.map(item => { const [longitude, latitude] = [...item.data[0].location.coordinates]; return { data: [{ latitude, longitude }] } }) console.log(newArr)

response.map((data: any) => {
  let newData = {"data" : []};
  let coords = {
    'latitude' : data.location.coordinates[2],
    'longitude' : data.location.coordinates[1]
  }
  newData.data.push(coords)
  return newData;
})
