Javascript 如何重命名iterably对象属性

每个对象属性都在第一个字母下面加下划线； 我想删除第一个子字符串，并尝试对所有对象属性使用字符串方法“replace”，但在这种情况下不起作用

// nested object
const posts = {
  // ...
  'post-meta-fields': {
    _bg_advantages_home: [''],
    _bg_banner_home: ['35'],
    _bg_info_1_home: ['41'],
    _bg_info_2_home: [''],
    _bg_offers_home: ['38'],
    _bg_sales_home: ['36'],
    _bg_video_home: ['']
  }
  // ...
};
// I tried this, but its not working
for (const key in posts['post-meta-fields']) {
  for (let key_2 in key) {
    key_2 = key_2.replace('_', '');
  }
}

现在只需删除旧密钥并添加新密钥：

let newKey = key_2.replace('_','');
key.newKey = key[key_2];
delete key[key_2];

也许你可以这样做

const tempObj = {};
for(let key in posts["post-meta-fields"]) {
     const modifiedKey = key.replace('_','');
     tempObj[modifiedKey] = posts["post-meta-fields"][key]
}
posts["post-meta-fields"] = tempObj;

希望你有一些想法

应该是

posts['post-meta-fields'][newKey]

，而不是

key。newKey

…点运算符在那里不起作用，基本对象不应该是

key

谢谢，它有助于解决此问题！！！
