如何重命名可迭代的对象属性

Question

每个对象属性的第一个字母都有下划线； 我想删除第一个子字符串，并尝试将字符串方法“替换”到所有对象属性，但在这种情况下它不起作用。

// 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('_', '');
  }
}

Answer 1

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！

Answer 2

现在你只需要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];
