formating Time stored as a number (HH:MM:SS)

[spsuffern]

We store time in a numeric field (6,0) (HHMMSS format). Is there a way to force leading zeros in a number when using ".toString". I didn't see anything in Valence APIs for converting a number with leading zeros. The code below works but I didn't know if there was a better method.

var atime = value.toString();
if (atime.length < 2) {
  atime = '00000' + atime;
}
if (atime.length < 3) {
  atime = '0000' + atime;
}
if (atime.length < 4) {
  atime = '000' + atime;
}
if (atime.length < 5) {
  atime = '00' + atime;
}
if (atime.length < 6) {
  atime = '0' + atime;
}
return atime.substr(0,2) + ':' + atime.substr(2,2) + ':' + atime.substr(4,2);

You could use padStart however IE doesn't support it. If you need to support IE you could write your own method like below.

function padString(str, size) {
    while (str.length < (size || 2)) {
        str = '0' + str;
    }
    return str;
}

// example
// 
console.log(padString('1', 5));

// expected output in the console would be "00001"

Thanks

Thanks Johnny. That makes sense.
