Question

I’m looking to turn 165 seconds into 2:40 not 0:2:45

The function needs to be able to adapt to how large the seconds value is.

I know there’s infinite ways to do this, but I’m looking for a clean way to do it without any external libraries other than jQuery.

Answer 1

Something like: [Math.floor(165/60),165%60].join(':') should work. Actually, it’s 2:45 ;~)

[edit] based on your comment a function to convert seconds into a (zero padded, hours trimmed) hr:mi:se string

function hms(sec){
 var   hr = parseInt(sec/(60*60),10)
     , mi = parseInt(sec/60,10)- (hr*60)
     , se = sec%60;
 return [hr,mi,se]
         .join(':')
         .replace(/\b\d\b/g,
            function(a){ 
             return Number(a)===0 ? '00' : a<10? '0'+a : a; 
            }
          )
         .replace(/^00:/,'');
}
alert(hms(165)); //=> 02:45
alert(hms(3850)); //=> 01:04:10
