Ich arbeite gerade an einem Skript, das die Zeit anzeigt, bis eine Periode in meiner Schule endet oder beginnt. Einer der Datensätze im Array muss davon ausgeschlossen werden, als Periode gezählt zu werden.JavaScript Time Exception Nachricht
{ start: minutes(11, 20), end: minutes(11, 46) },
Ich möchte diese Daten auszuschließen, weil seine nicht ein vollwertiges Zeit, sein Mittagessen und im nicht sicher, wie ich über das Tun es gehen sollte. Irgendwelche Ideen? Außerdem müsste die Nachricht an den Benutzer anstatt geändert werden.
document.getElementById("result").innerHTML = "There are " + timeLeft + " minutes left until period " + (i+1) + " is over."
Irgendwelche Ideen?

Sie haben vergessen, eine Frage zu stellen. – Ibu
Können Sie diesem Datenelement eine weitere Eigenschaft hinzufügen, 'isLunch = true'? – Amy
