How to deserialize JSON timespan in javascript

Question

I have created a C# REST WCF service which return a timespan. In client side I am getting JSON serialized return value like PT14H,PT16H etc. How to convert this string to actual timespan?

Answer 1

JavaScript does not have a TimeSpan data type, but you can use moment.js.

Moment.js supports ISO 8601 time intervals (just like .NET TimeSpan), they're called durations.

It includes the basic arithmetic operations: if you substract dates you get durations, if you add dates and durations you get dates, if you add or substract durations you get durations just like .NET DateTime and TimeSpan.

Example:

var now= moment();
// 7 hour time span
var timeSpan = moment.duration('PT7H');

// addition
alert(now.add(timeSpan).format());

<script src="//cdnjs.cloudflare.com/ajax/libs/moment.js/2.11.2/moment.min.js"></script>

In my case JSON result looks like PT14H represent time 14:00:00 and PT9H25M25S represent time 9:25:25. That means PT represent time part, H represent hourse part, M represent minute part and S represent seconds part.
