[Javascript] Event "Handlers" (Literally)

[Flavio Gomes]

  Let me show you what I really have got, maybe you guys have got a 
better solution.

  I got a simple form with no "submit button" that I want to be submited 
when the user changes it and leaves (onchange event) or when the user 
hits return (actual onsubmit), but I need to validate what the user 
entered: it must be and integer greater than zero and lower than a 
certain number that I obtain from PHP, let's say 8 for example.
  On the onsubmit event I return false to any non valid entries, but if 
I do the same on the onchange, It wont stop the submission.
  The solution I found was to create two separate functions, that seems 
to work, but I simply think it's not object oriented and will bring 
problems to maintenance.

Any better ideas?
