获取对象 React Native 的列表属性

福赞里塞克

我不想获取数组中每个对象的 ID。
我有这个数组

[
  {
    "-ML8Lx8jOSv64Ecat611": {
      "category": "Automotive Parts & Accessories",
      "description": "I will be there at least but I don't know if I can help in any way I can",
      "item": "Apple Watch",
      "price": "429,99",
      "timestamp": "2020-11-02T21:28:11+07:00",
      "viewCount": 0
    }
  }
]

我期望得到的是

[
  {
      "category": "Automotive Parts & Accessories",
      "description": "I will be there at least but I don't know if I can help in any way I can",
      "item": "Apple Watch",
      "price": "429,99",
      "timestamp": "2020-11-02T21:28:11+07:00",
      "viewCount": 0
  }
]

由于您想要在输出中的对象是嵌套的，您需要在 JSON 中循环两个级别：

let input = [
  {
    "-ML8Lx8jOSv64Ecat611": {
      "category": "Automotive Parts & Accessories",
      "description": "I will be there at least but I don't know if I can help in any way I can",
      "item": "Apple Watch",
      "price": "429,99",
      "timestamp": "2020-11-02T21:28:11+07:00",
      "viewCount": 0
    }
  }
];

let result = []
input.forEach(obj => {
  Object.keys(obj).forEach(key => {
    result.push(obj[key]);
  });
});

console.log(result);
