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

Question

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

Answer 1

I'm using version 2.11 of Fullcalendar and i made some change to code posted by ecruz:

function isOverlapping(event){
   var array = calendar.fullCalendar('clientEvents');
   for(i in array){
       if(array[i]._id != event._id){
           if(!(array[i].start.format() >= event.end.format() || array[i].end.format() <= event.start.format())){
               return true;
           }
       }
    }
        return false;
}

and this is how i use to prevent the overlap:

    $('#calendar').fullCalendar({
        ...
        eventDrop: function(event, delta, revertFunc) {
                        if (isOverlapping(event)) {
                            revertFunc();
                        }
        },
        ...
    });
