如何转换为 24 小时格式（谷歌应用程序脚本）

Question

 function dailyEventMessage() {  var googleCalendarId = "[e-mail]";  var calendar = CalendarApp.getCalendarById(googleCalendarId);  var today = new Date();  var tomorrow = new Date(today.getFullYear(), today.getMonth(),today.getDate()+1);  var tomorrowEventList = calendar.getEventsForDay(tomorrow);  const date = new Date(tomorrow)   const tomorrowdateresult = date.toLocaleDateString('th-TH', {  year: 'numeric',  month: 'long',  day: 'numeric',  weekday: 'long', })  var message = "";  for (var i = 0; i < tomorrowEventList.length; i++) {  var eventTitle = "Task: "   + tomorrowdateresult + "\n" + "**"+  tomorrowEventList[i].getTitle()+"**";   var eventTime = "Timebegin: "  + tomorrowEventList[i].getStartTime().toTimeString().slice(0,5)+"-"+ tomorrowEventList[i].getEndTime().toTimeString().slice(0,5);  var eventDescription = "Details: "  + tomorrowEventList[i].getDescription();   message += "\n" + eventTitle + "\n" + eventTime + "\n" + eventDescription + "\n";   }  if (message === "") {   return;  }  Logger.log(message); sendMessage(message);  }我发现的问题是变量 eventtime，它显示为 12 小时格式。前任。03.00-04.00 但实际上我在谷歌日历中设置的时间为 15.00-16.00谁能建议如何将其更改为 24 小时格式。Thks

如果您使用日期格式化程序，您的代码会更干净。通过使用toTimeString()，slice(0,5)你的代码有时会崩溃。

Intl.DateTimeFormat您可以将hour12配置设置为false. 它将为您提供 24 小时格式。

const startTime = new Date(2010, 11, 12, 13, 14);

const endTime = new Date(2010, 11, 12, 16, 17);

const formatter = new Intl.DateTimeFormat('en', {

    hour: 'numeric',

    minute: 'numeric',

    hour12: false,

});

console.log(`${formatter.format(startTime)} - ${formatter.format(endTime)}`);
