I got an ISO 8601 string as duration and I need to format it as XhYm( 1h20m). Does anyone have some suggestions?

What I did right now is this:

const duration = moment.duration(secondData.duration);
const formatted = moment.utc(duration.asMilliseconds()).format('HH:mm');

• 3 and what is wrong when you try your code? You didn't make clear. Also please show us the input string from which you want to produce your stated result. – ADyson Commented Jan 9, 2019 at 14:08
• The input string is PT1H20M and I want to format is as 1h20m, with my code it formats as 01:20 @ADyson – user8991667 Commented Jan 9, 2019 at 14:10

• Actually I'm trying to clarify what you're doing, in order to do exactly that. Ok so it's a duration string, I'm sorry I didn't quite catch that, sorry for misreading. But still, please answer what is secondData and how did you populate it? The example is still incomplete. – ADyson Commented Jan 9, 2019 at 14:15

To get the output format you want, you'll need to set up the format string differently in the format() call:

const duration = moment.duration('PT1H20M');
const formatted = moment.utc(duration.asMilliseconds()).format("H[h]m[m]");

Using the square brackets makes moment print those characters without trying to use them in the format. See the Escaping Characters in the momentjs documentation.

The simplest way to do it involves a little bit of manual formatting:

var d = moment.duration("PT1H20M");
console.log(d.hours()+"H"+d.minutes()+"M");
