Check time difference in Javascript

Question

How would you check time difference from two text-boxes in Javascript?

Answer 1

Here's the solution that worked for me:

var date1 = new Date("08/05/2015 23:41:20");
var date2 = new Date("08/06/2015 02:56:32");

var diff = date2.getTime() - date1.getTime();

var msec = diff;
var hh = Math.floor(msec / 1000 / 60 / 60);
msec -= hh * 1000 * 60 * 60;
var mm = Math.floor(msec / 1000 / 60);
msec -= mm * 1000 * 60;
var ss = Math.floor(msec / 1000);
msec -= ss * 1000;

alert(hh + ":" + mm + ":" + ss);
