Javascript 如何更改json对象的所有属性名

我想更改json对象的所有属性名

const obj = {
  "country": "Value1",
  "area": "value2",
  "color_flag": "value3"
}

const newKeys = ["pays", "Superficie", "Couleur de drapeau"]

// I would like to have something like this : 

obj = {
  "pays": "Value1",
  "superficie": "Value2",
  "couleur_drapeau": "Value3"
}

提前感谢

您可以使用新关键点克隆对象，但您需要为新关键点提供如下地图：

const newKeys = {
  "country": "pays",
  "area": "superficie",
  "color_flag": "couleur_drapeau"
}

const obj = {
  "country": "Value1",
  "area": "value2",
  "color_flag": "value3"
}

const newKeys = { // Keys map
  "country": "pays",
  "area": "superficie",
  "color_flag": "couleur_drapeau"
}

const renamedObj = {}
for(let key in obj){
  const newKey = newKeys[key]
  renamedObj[newKey] = obj[key]
}

renamedObj = {
  "pays": "Value1",
  "superficie": "Value2",
  "couleur_drapeau": "Value3"
}

只需在左边放上原来的钥匙，在右边放上新的钥匙，在你的例子中是法语的翻译

然后，需要在原始对象的所有关键点上循环，并使用新关键点将每个值复制到新对象

const renamedObj = {}
for(let key in obj){
  const newKey = newKeys[key]
  renamedObj[newKey] = obj[key]
}

最终代码应如下所示：

const newKeys = {
  "country": "pays",
  "area": "superficie",
  "color_flag": "couleur_drapeau"
}

const obj = {
  "country": "Value1",
  "area": "value2",
  "color_flag": "value3"
}

const newKeys = { // Keys map
  "country": "pays",
  "area": "superficie",
  "color_flag": "couleur_drapeau"
}

const renamedObj = {}
for(let key in obj){
  const newKey = newKeys[key]
  renamedObj[newKey] = obj[key]
}

renamedObj = {
  "pays": "Value1",
  "superficie": "Value2",
  "couleur_drapeau": "Value3"
}

renamedObj

应如下所示：

const newKeys = {
  "country": "pays",
  "area": "superficie",
  "color_flag": "couleur_drapeau"
}

const obj = {
  "country": "Value1",
  "area": "value2",
  "color_flag": "value3"
}

const newKeys = { // Keys map
  "country": "pays",
  "area": "superficie",
  "color_flag": "couleur_drapeau"
}

const renamedObj = {}
for(let key in obj){
  const newKey = newKeys[key]
  renamedObj[newKey] = obj[key]
}

renamedObj = {
  "pays": "Value1",
  "superficie": "Value2",
  "couleur_drapeau": "Value3"
}

您将如何将哪个旧密钥映射到哪个新密钥？对象未排序。这将是另一个属性。分配后

obj.pays=obj.country；删除obj.country，如果这些是基本值。您已经尝试过什么？如果
新密钥
可以包含
obj
的密钥子集，请改用
重命名bj[newKey | | key]=obj[key]
。如果找不到新键的真实值，则使用旧键。否则，这是一个很好的答案。
