Hi
I am trying to call different javascript functions using onSubmit event.
My problem is that only one function (first one) works at same time (see attached code). The second function is simply ignored. If I cancell first funtion, the second one works perfectly.

Can you tell me how to call two o more functions at same time, using same event?

Thanks


<form ACTION="<%=MM_editAction%>" METHOD="POST" name="form_Utente" onsubmit="return Controlla_Data(data_nascita.value,'Data di nascita'); return Controlla_Mail(email.value);">

Well, Javascript is not designed to be multi-threaded.
Normally, there is only one thread of control.  So, the
statements that you have, i.e.,

return Controlla_Data(data_nascita.value,'Data di nascita');
return Controlla_Mail(email.value);

can not allow the second function to be called.  What
happens is that the first routine (i.e., Controlla_Data()) is
called, and the result that is returned is used as a return
value during the submit processing.

You probably want something like:

return Controlla_Data(data_nascita.value,'Data di nascita') ||  Controlla_Mail(email.value);

This construct, i.e.,

function#1() || function#2()

will invoke both.  However, it expects the returned values to
be boolean.  If they aren't we have to do something else...

return (function1 && function2); worked just fine. Thanks!
