Convert seconds to HH-MM-SS with JavaScript?

Question

How can I convert seconds to an HH-MM-SS string using JavaScript?

Answer 1

Here is a function to convert seconds to hh-mm-ss format based on powtac's answer here

jsfiddle

/** 
 * Convert seconds to hh-mm-ss format.
 * @param {number} totalSeconds - the total seconds to convert to hh- mm-ss
**/
var SecondsTohhmmss = function(totalSeconds) {
  var hours   = Math.floor(totalSeconds / 3600);
  var minutes = Math.floor((totalSeconds - (hours * 3600)) / 60);
  var seconds = totalSeconds - (hours * 3600) - (minutes * 60);

  // round seconds
  seconds = Math.round(seconds * 100) / 100

  var result = (hours < 10 ? "0" + hours : hours);
      result += "-" + (minutes < 10 ? "0" + minutes : minutes);
      result += "-" + (seconds  < 10 ? "0" + seconds : seconds);
  return result;
}

Example use

var seconds = SecondsTohhmmss(70);
console.log(seconds);
// logs 00-01-10
