var expmail = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-]{2,})+\.)+([a-zA-Z0-9]{2,})+$/;
var expnome = /^[a-zA-Z ]+$/;


if((modulo.nome.value=="")||(modulo.nome.value.length<3)||(modulo.nome.value.length>15)||(!expnome.t est(modulo.nome.value))){
alert("Il nome obb, min 3 e max 15 caratteri");
modulo.nome.focus();

return false;
}

if(modulo.email.value=="") {
alert("Attenzione! Inserisci l'e-mail.");
modulo.email.focus();
return false;
}
if(!expmail.test(modulo.email.value)){
alert("La mail inserita non e' valida!");
modulo.email.focus();
return false;
}
if((modulo.eta.value!="")&& (modulo.eta.value<18 || modulo.eta.value>99)){
alert("Eta' non valida, dev'essere compresa tra 18 e 99! ");
modulo.eta.focus();
return false;
}
if(modulo.user.value=="") {

if((modulo.pass.value=="")||(modulo.pass.value.length<6)) {
alert("Attenzione! La password e' un campo obbligatorio e deve contenere almeno 6 caratteri.");
modulo.pass.focus();
return false;
}
if(modulo.pass2.value=="") {
alert("Attenzione! Conferma la password.");
modulo.pass2.focus();
return false;
}
if((modulo.pass.value) != (modulo.pass2.value)) {
alert("Le password non coincidono!");
