我想在 ActivityDate 中按日期對我的數組進行排序，但它沒有對任何內容進行排序。它是一個包含對象的數組，ActivityDate 是每個對象的一個字段。如果您查看最后的輸出，您會看到一個 Date 應該在日志中排在第一位，但它仍然在最后，因為它與 Array1 連接在一起。const dummy = "2020-06-01T22:00:00.000Z";const Array2 = [{"activitydate":"2020-06-01T22:00:00.000Z","name":"Pfingstmontag","hourstype":"H","state":1}]const ArrFinal = Array1.concat(Array2).sort((a, b) => Date.parse(new Date(...a.activitydate.toString().split("-")[2])) - Date.parse(new Date(...b.activitydate).toString().split("-")[2]))console.log(JSON.stringify(ArrFinal))console.log(dummy.split("-")[2])

property 中的字符串采用activitydate的格式可以使用 自動解析new Date(DATE_IN_STRING)。
只需解析日期并按Date對象排序。
const ArrFinal = Array1.concat(Array2).sort((a, b) => new Date(a.activitydate) - new Date(b.activitydate));
這很好用。
