Use the
IOL technique with code similar to this:
$("input[name=_fid_6]").on("change", function() {
if ($("input[name=_fid_6]").val() != $("input[name=_fid_oval_6]").val()) {
$("input[name=_fid_7").val(parseInt($("input[name=_fid_oval_7").val(), 10) + 1);
}
});
fid 6 is the
date field and
fid 7 is the
counter. The code basically monitors the date for changes and when the date is not equal to its old value take the old value of the counter, add one and place this incremented value in the new counter field.
