That's true - I didn't change it because I thought there could be some cases
where alertSave() could be called outside of the 'a' thing - if that's not
the case, then this version is definitely better. You could go so far as to
eliminate the variable as well and just do:
if ($('#changedAppointments').attr("value").length > 0) { return
confirm(<MESSAGE>); }
Since you don't use dataControl more than the one time, there's really
little need for it.
