Martin Honnen,

JavaScript has a 
  toString(numberBase)
method for that so by calling
  toString(16)
on a number you get a string with the hexadecimal representation of the 
number, by calling
  toString(2)
you get the binary representation, by calling
  toString(8)
you get the octal representation. That works for bases from 2..16.
Examples
  var n = 10;
  alert(n.toString(16));
  alert(n.toString(8));
  alert(n.toString(2));
