將行追加到JSON

Question

向數據庫添加行后如何將數組附加到JSON

[
  {id: 1, content: "aaaa", date: "2017-12-05T23:00:00.000Z"},
  {id: 2, content: "bbbb", date: "2017-13-05T23:00:00.000Z"},
  {id: 3, content: "cccc", date: "2017-13-05T23:00:00.000Z"},
  {id: 4, content: "dddd", date: "2017-14-05T23:00:00.000Z"},
  {id: 5, content: "eeee", date: "2017-14-05T23:00:00.000Z"},
]

然后在日期為2017-13-05T23:00:00.000Z數據庫中添加quest ，以及如何顯示此視圖，但是我必須將此行添加到日期為2017-13-05T23:00:00.000Z最后一個值中2017-13-05T23:00:00.000Z 。

如果您希望按日期對數組進行排序，則可以使用push ，然后按日期對數組進行sort ，如下所示：

 const array = [ {id: 1, content: "aaaa", date: "2017-12-05T23:00:00.000Z"}, {id: 2, content: "bbbb", date: "2017-13-05T23:00:00.000Z"}, {id: 3, content: "cccc", date: "2017-13-05T23:00:00.000Z"}, {id: 4, content: "dddd", date: "2017-14-05T23:00:00.000Z"}, {id: 5, content: "eeee", date: "2017-14-05T23:00:00.000Z"}, ] const rowToInsert = {id: 6, content: "ffff", date: "2017-13-05T23:00:00.000Z"} array.push(rowToInsert) array.sort(function (a, b) { return a.date > b.date; }) console.log(array)
