javascript - Is there any conditional formatting in moment.js? -

i working on countdown using moment.js.
nice if have conditional formatting.

here have

var count_down = moment().hour(23).min(30); alert( count_down.format('h[h ]m[min ]s[s]') );

that displays:

0h 43min 20s

i know if there format expression

var format = 'h[h ]m[min ]s[s]'; if (count_down.hour() === 0)    format = 'm[min ]s[s]'; alert( count_down.format(format) );

displaying:

43min 20s

i have not seen in doc though.

a moment object represents time-of-day, not make sense count-down. should use moment's duration object purpose instead.

moment doesn't yet have direct support formatting durations, this:

var d = moment.duration('23:30'); var s = (d.hours() > 0 ? d.hours() + 'h ' : '')         + d.minutes() + 'min '         + d.seconds() + 's';

alternatively, can try moment-duration-format plugin, still have handle conditional evaluation yourself.
