How would I format amount field with ma and decimal?
I am able to get mas but this function does not allow decimal in the field.

$('input.number').keyup(function(event) {

  // skip for arrow keys
  if(event.which >= 37 && event.which <= 40){
    event.preventDefault();
  }

  $(this).val(function(index, value) {
    return value
      .replace(/\D/g, "")
      .replace(/\B(?=(\d{3})+(?!\d))/g, ",")
    ;
  });
});

Is this what you had in mind?

$('input.number').keyup(function(event) {

  // skip for arrow keys
  if(event.which >= 37 && event.which <= 40){
    event.preventDefault();
  }

  $(this).val(function(index, value) {
    return value
      .replace(/\D/g, "")
      .replace(/([0-9])([0-9]{2})$/, '$1.$2')  
      .replace(/\B(?=(\d{3})+(?!\d)\.?)/g, ",")
    ;
  });
});
