JavaScript seconds to time string with format hh:mm:ss
String.prototype.toHHMMSS = function () { var sec_num = parseInt(this, 10); // don't forget the second param var hours = Math.floor(sec_num / 3600); var minutes = Math.floor((sec_num - (hours * 3600)) / 60); var seconds = sec_num - (hours * 3600) - (minutes * 60); if (hours < 10) {hours = "0"+hours;} if (minutes < 10) {minutes = "0"+minutes;} if (seconds < 10) {seconds = "0"+seconds;} return hours+':'+minutes+':'+seconds;}You can use it now like:
alert("5678".toHHMMSS());Working snippet:
You can manage to do this without any external JS library with the help of JS Date method like following:
var date = new Date(0);date.setSeconds(45); // specify value for SECONDS herevar timeString = date.toISOString().substr(11, 8);console.log(timeString)
To get the time part in the format hh:MM:ss, you can use this regular expression:
(This was mentioned above in same post by someone, thanks for that.)
var myDate = new Date().toTimeString().replace(/.*(\d{2}:\d{2}:\d{2}).*/, "$1"); console.log(myDate)
