Formatting MomentJS duration above 24 hours

问题

I would like to format a summed up total working hours e.g. 49.75 to this: 49:45.

When I use duration like this:

const dur = moment.duration(49.75, 'hours').asMilliseconds();
moment.utc(dur).format("HH:mm:ss") // 01:45:00

I'll receive 01:45:00 instead of 49:45:00

Is there a way to format (instead of HH) duration without dropping the days?

回答1:

I recommend you this answer.

You can add a format for the duration, and it works for greater than 24 Hour.

function(input) {
    input = input || '';
    var out = '';
    var dur = moment.duration(input, 'minutes');
    return dur.format('HH:mm:ss');
};

I hope it can help you!

EDIT:

This code uses duration-format plugin!

I think you cannot use format but build it manually:

var dur = moment.duration(49.75, 'hours');
var hours = Math.floor(dur.asHours());
var mins  = Math.floor(dur.asMinutes()) - hours * 60;
var sec   = Math.floor(dur.asSeconds()) - hours * 60 * 60 - mins * 60;

var result = hours + ":" + mins + ":" + ((sec > 9) ? sec : ("0"+sec));
console.log(result); // 49:45:00

Fiddle

^{Hope someone will find more elegant way}
