Hi,
My guess (untested, don't know about interplay with alert) is if you
through in a defer[1], it'll work:
else {
(function(){
$(this).focus();
}).defer();
alert("invalid number");
return false;
}
...but that the user experience won't be great for a variety of
reasons (not least because the focus will go to the new field, then
revert to the previous one; and separately, alerts are not great user
experience).
Can I suggest instead, that you validate fields without getting in the
user's way (interfering with their navigation), providing a visual
clue that the field value is not okay (perhaps a red border around the
field, an icon next to it, etc.), and if the user tries to send the
information anyway, at that point using a more intrusive mechanism
(perhaps an alert) to tell them that there are issues and to deal with
the highlighted fields.
