数组按时间排序hh:mm:ss [英] Array Sort by time hh:mm:ss

问题描述

我正在尝试整理时间.但我无法按时间(hh:mm:ss)格式排序.所以我用过矩js.我的数组按时间排序没有得到排序.如何使用地图对数组进行排序

I am trying to sort the time. but I am unable to sort by time (hh:mm:ss) format. so i have used moments js. my array sort by time not get sorted. how sort array by using maps

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 })));

推荐答案

您可以使用

You can lexicographical sort the time using 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; }
