JavaScript 对日期和时间进行降序排序

Question

<分区>

Answer 1

只需连接date 和time，然后将其解析为Date 并获取时间戳。从那时起，它只是普通的旧排序。

const datetimes = [
  {chatroomID: "1", date: "12/26/2017", time: "10:31:32 PM"},
  {chatroomID: "2", date: "12/26/2017", time: "10:38:01 PM"},
  {chatroomID: "3", date: "12/26/2017", time: "10:35:14 PM"}
]

const sorted = datetimes.sort((a, b) => {
  const aDate = new Date(a.date + ' ' + a.time)
  const bDate = new Date(b.date + ' ' + b.time)
  
  return bDate.getTime() - aDate.getTime()
})

console.log(sorted)

更新:Marcel Gwerder 评论中的链接答案表明您可以完全跳过 getTime() 并只比较日期。
