javascript - 按动态键对嵌套对象数组进行排序

Question

我相信我对这个问题的措辞是正确的......我有一个这样的数据集......

[
  {
    "Fri Aug 03 2018 00:00:00 GMT-0500": {
      "bill": "Test 2",
      "account": "defaultAccount",
      "amount": 40,
      "category": "defaultCategory",
      "description": "231"
    }
  },
  {
    "Fri Aug 17 2018 00:00:00 GMT-0500": {
      "bill": "Test 2",
      "account": "defaultAccount",
      "amount": 40,
      "category": "defaultCategory",
      "description": "231"
    }
  },
  {
    "Wed Aug 01 2018 00:00:00 GMT-0500": {
      "bill": "test",
      "account": "create-account",
      "amount": 40,
      "category": "mortgage",
      "description": "23"
    }
  }, ....
]

我正在努力根据对象的动态日期对数组进行排序。在过去的几个小时里，我一直在研究这个关于堆栈溢出的问题的每个版本，但我没有提出解决方案……非常感谢任何建议!

您需要获取每个外部对象的键并获取一个日期对象。然后取delta进行排序。

var array = [{ "Fri Aug 03 2018 00:00:00 GMT-0500": { bill: "Test 2", account: "defaultAccount", amount: 40, category: "defaultCategory", description: "231" } }, { "Fri Aug 17 2018 00:00:00 GMT-0500": { bill: "Test 2", account: "defaultAccount", amount: 40, category: "defaultCategory", description: "231" } }, { "Wed Aug 01 2018 00:00:00 GMT-0500": { bill: "test", account: "create-account", amount: 40, category: "mortgage", description: "23" } }];

array.sort((a, b) => new Date(Object.keys(a)[0]) - new Date(Object.keys(b)[0]));

console.log(array);

.as-console-wrapper { max-height: 100% !important; top: 0; }
