javascript - 如何从字典中提取项目

Question

我有一本看起来像这样的字典:

"Player Details": {
    "Sally Smith": {
        "player_id": 2,
        "color_one": "blue",
        "color_two": "red"
    },
    "John Smith": {
        "player_id": 4,
        "color_one": "white",
        "color_two": "black"
    }
}

我需要它进入一个数组并像这样结束:

"Player details": [
    {
        "player_id": "2",
        "color_one": "blue",
        "color_two": "red"
    },
    {
        "player_id": "4",
        "color_one": "white",
        "color_two": "black"
    }
]

我尝试了以下方法，但“值”仍然存在:

Object.entries(myDictionary).forEach(([key, value]) => {
   newArray.push({value})
});

我觉得我快到了，有人可以帮忙吗？

只需使用 Object.values 从对象中获取值返回数组中的对象属性值的方法。

let data = {
  "Player Details": {
    "Sally Smith": {
      "player_id": 2,
      "color_one": "blue",
      "color_two": "red"
    },
    "John Smith": {
      "player_id": 4,
      "color_one": "white",
      "color_two": "black"
    }
  }
}


let res = {
  'Player Details': Object.values(data['Player Details'])
};

// or in case you justt need the array then 
let res1 = Object.values(data['Player Details']);

console.log(res)
console.log(res1)

仅供引用:由于您的属性中有空格，您不能使用 dot notation访问属性而不是使用 bracket notation .
