hi all,  
i want to find out the age of a person in the simple registration form  
without submitting the form.  
we can use link\_to\_remote or submit\_to\_remote(…), but i don’t want  
to use any link or button to link to the controller. Can we use  
date\_select as one observe\_field or any other possibility to do this…

plz guide me to do this…
