数组 按时间排序 hh:mm:ss

Question

我正在尝试对时间进行排序。但我无法按时间 (hh:mm:ss) 格式排序。所以我使用了 moment js。我的数组按时间排序未排序。如何使用映射对数组进行排序

我有一个对象数组：

let elements =[
  {
    "id": 1,
    "date": "02:01:02"
  },
  {
    "id": 2,
    "date": "01:01:01"
  },
  {
    "id": 3,
    "date": "03:01:01"
  },
  {
    "id": 4,
    "date": "04:01:01"
  }
 ]; 


 let parsedDates = new Map(
        elements.map(e =>[["id", "date"],[e.id, moment(e.date, 'hh:mm:ss')]])
        );

    elements.sort((a, b) => parsedDates.get(a) - parsedDates.get(b));

    console.log(elements.map(e => ({ id: e.id, date: e.date })));

您可以使用string.localeCompare().

let times = [ { "id": 1, "date": "02:01:02" }, { "id": 2, "date": "01:01:01" }, { "id": 3, "date": "03:01:01" }, { "id": 4, "date": "04:01:01" } ];
times.sort((a,b) => a.date.localeCompare(b.date));
console.log(times);

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