Javascript 如何将对象的数组转换为一维数组？

我有一个javascript对象数组的例子，在一个对象中有一个对象。所以我基本上只想把它放到一维数组中

我已经搜索了很多Q，但没有一个符合我的要求

我所拥有的

[
{
"id": "59cf758f7bdf8d2e0c1c68c7",
"value": {
  "city": "Mahbubnagar",
  "state": "Andhra Pradesh",
  "country": "India"
}
},
{
"id": "59cf758f7bdf8d2e0c1c68c8",
"value": {
  "city": "Udgir",
  "state": "Maharashtra",
  "country": "India"
}
},
{
"id": "59cf758f7bdf8d2e0c1c68c9",
"value": {
  "city": "Umarga",
  "state": "Maharashtra",
  "country": "India"
}
},
{
"id": "59cf758f7bdf8d2e0c1c68ca",
"value": {
  "city": "Umarkhed",
  "state": "Maharashtra",
  "country": "India"
}
},
{
"id": "59cf758f7bdf8d2e0c1c68cb",
"value": {
  "city": "Umred",
  "state": "Maharashtra",
  "country": "India"
}
}
]

我只是想把这个对象数组变成一个数组

[
  "59cf758f7bdf8d2e0c1c68c7",
  "Mahbubnagar",
  "Andhra Pradesh",
  "India",
],[
  "59cf758f7bdf8d2e0c1c68c9",
  "Umarga",
  "Maharashtra",
  "India",
],[
  "59cf758f7bdf8d2e0c1c68ca",
  "Umarkhed",
  "Maharashtra",
  "India",
],[
  "59cf758f7bdf8d2e0c1c68c7",
  "Mahbubnagar",
  "Andhra Pradesh",
  "India",
],

对象数组可以有更多的子对象，换句话说，你可以说它的动态内容

到目前为止，我使用的是

var object= property.value.elements;
        var finalArray = object.map(function (obj) {
          return obj.id;
        });
        console.log(finalArray);

只给了我一张身份证的清单

这不是重复的问题，请在将其标记为重复之前进行验证。

尝试以下操作

var arr=[{id:59cf758f7bdf8d2e0c1c68c7，值：{city:Mahbubnagar，state:Andhra Pradesh，country:India}}，{id:59cf758f7bdf8d2e0c1c68c8，值：{city:Udgir，state:Maharashtra，country:India}，{id:59CF758F7BDF8D2E0C68C9，值：{city:Umargarga，state:Maharashtra，country:India}，{id:CF758D08C68C8，country:Maharashtra，country:India}，{id:59cf758f7bdf8d2e0c1c68cb，值：{城市：乌姆雷德，州：马哈拉施特拉邦，国家：印度}}]； 函数getValsobj，arr{ Object.entriesobj.forEach[键，值]=>{ iftypeof值===对象{ arr=[…arr，…getValsobj[key]，arr]； }否则{ arr.pushvalue； } }; 返回arr； } var resp=arr.mapitem=>{ 设temp=[]； 获取项目，温度； 返回温度； };

console.logresp；您可以检查对象的值是否为对象，并获取结果的展平值

函数平面对象{ 返回对象 .价值主体 .reducer，v=>r.concatv和&typeof v=='object'？flatv:v，[]； } var数组=[{id:59cf758f7bdf8d2e0c18c7，值：{city:mahbunagar，state:Andhra Pradesh，country:India}}，{id:59cf758f7bdf8d2e0c18c8，值：{city:Udgir，state:Maharashtra，country:India}，{id:59cf758f7bdf8d2e0c18c9，值：{city:Umarga，state:Maharashtra，country:India}，{id:59cf758d7bdf8c8c8c8c8c8c8c8c8c8c8c8c8c8c6c8，值：{城市：乌马尔基德，州：马哈拉施特拉，国家：印度}，{id:59cf758f7bdf8d2e0c1c68cb，值：{城市：乌姆雷德，州：马哈拉施特拉，国家：印度}]， 结果=array.mapflat； console.logresult；

.as console wrapper{max height:100%！important；top:0；}这不是最简单的方法。只需循环所有对象并提取它们的值

let x = [{"id": "59cf758f7bdf8d2e0c1c68c7", "value": {...}, ..] 
let res = []

x.forEach((obj, index) => {
  res.push([obj.id, obj.value.city, obj.value.state, obj.value.country])
}) 

console.log(res)

您的示例输出在语法上不正确。怎么不正确？@ninesaltI已经添加了我尝试过的内容@NinaScholzCopy/再次粘贴您的输出…您发布的内容不正确您的输出只是一系列未包装在数组中的数组。您可能想将字符串包装在对象[{}，{}…]这对数组中的多个级别的对象有效吗？还是只对两个级别的@nikhilThanks很多@nikhil有效
