javascript - 迭代 JSON 以仅更新单个元素

Question

我有以下 JSON。我将如何在纯 JavaScript 中迭代此操作以仅更新 bCoords 的坐标？

    { aCoordinates: { latitude: 22.572646, longitude: 88.36389500000001 },
  bCoordinates: { latitude: 22.572646, longitude: 88.36389500000001 } }

Answer 1

为什么要迭代？直接访问即可:

let data = {
  aCoordinates: {
    latitude: 22.572646,
    longitude: 88.36389500000001
  },
  bCoordinates: {
    latitude: 22.572646,
    longitude: 88.36389500000001
  }
}

data.bCoordinates.latitude = 1
data.bCoordinates.longitude = -1

console.log(data)
