Question

Is there a way to prevent overlapping events in jQuery FullCalendar?

Answer 1

Same as Matthew Webb but Following worked for me since sometimes my end date was null when i was dragging the event from allDay to some time slot

function isOverlapping(event) {
    var arrCalEvents = $('#' + g_str_FullCalenderID).fullCalendar('clientEvents');
    for (i in arrCalEvents) {
        if (arrCalEvents[i].id != event.id) {
            if ((event.end >= arrCalEvents[i].start && event.start <= arrCalEvents[i].end) || (event.end == null && (event.start >= arrCalEvents[i].start && event.start <= arrCalEvents[i].end))) {//!(Date(arrCalEvents[i].start) >= Date(event.end) || Date(arrCalEvents[i].end) <= Date(event.start))
                return true;
            }
        }
    }
    return false;
}
