Hi All, sorry for my silly question…  
How to make an Ajax Request when the item in Select Box change ? So  
when I change the item in select box I like to partial refresh some of  
my page with new item choosen in select box… but I want to do it  
without pressing any button at all so actually I want to use onchange  
select box event, but how can I do it using prototype ?
