Answer 1

Assuming you have those values stored in some strings, try this:

function pad (str, max) {   str = str.toString();   return str.length < max ? pad("0" + str, max) : str; }  pad("3", 3);    // => "003" pad("123", 3);  // => "123" pad("1234", 3); // => "1234"  var test = "MR 2"; var parts = test.split(" "); parts[1] = pad(parts[1], 3); parts.join(" "); // => "MR 002" 

Answer 2

I have a potential solution which I guess is relevent, I posted about it here:

basically, you want a minimum length of 2 or 3, you can adjust how many 0's you put in this piece of code

var d = new Date(); var h = ("0"+d.getHours()).slice(-2); var m = ("0"+d.getMinutes()).slice(-2); var s = ("0"+d.getSeconds()).slice(-2); 

I knew I would always get a single integer as a minimum (cause hour 1, hour 2) etc, but if you can't be sure of getting anything but an empty string, you can just do "000"+d.getHours() to make sure you get the minimum.

then you want 3 numbers? just use -3 instead of -2 in my code, I'm just writing this because I wanted to construct a 24 hour clock in a super easy fashion.
