如何在不到小时的时间内获取格式“00:34”moment.js

Question

I have duration like:

{
_isValid: true
_milliseconds: 2040000
_days: 0
_months: 0
_data: {milliseconds: 0, seconds: 0, minutes: 31, hours: 3, days: 0, …}
_locale: Locale {_calendar: {…}, _longDateFormat: {…}, _invalidDate: "Invalid date", _dayOfMonthOrdinalParse: /\d{1,2}(th|st|nd|rd)/, ordinal: ƒ, …}
__proto__: Object
}

if I make duration.format("HH:mm") I get "34", how can I get "00:34"?

My code where I use this:

duration: timeEntries
            .slice(1)
            .reduce((prev, cur) => {
              return prev.add(cur.duration);
            }, moment.duration(timeEntries[0].duration))
            .format("HH:mm")

and my duration is 34, instead of 00:34, because duration is less than hour, in other cases, where time is bigger, it return a 1:30 for example

Try this

Duration object has _data which contains the time object we need for formatting.

 //moment(moment.duration(duration_value)._data).format("HH:mm"); console.log(moment(moment.duration(3500000)._data).format("HH:mm"));
