  5. }).blur(function(){
  6. if($(this).val() == symbol) {
  7. $(this).attr('value', '');
  8. } else {
  9. s = $(this).val();
  10. s = $.numAddCommas(s); // Add commas to long digit strings - you will need to get a function to do this (find one on snipplr)
  11. $(this).attr('value', s);
  12. var hascur = s.indexOf(symbol);
  13. if(hascur) $(this).attr('value', symbol+s);
