How do I delete this event from FullCalendar?

Question

The calendar lets the user drag a timeslot onto the calendar, however I would like them to be able to remove it if they click on it.

So in the eventClick I have this fun

Answer 1

I use filter function with event.start and it works well

calendar.fullCalendar('removeEvents', function(event) {
  return 
    $.fullCalendar.formatDate(event.start, 'yyyyMMdd') 
    == $.fullCalendar.formatDate(start, 'yyyyMMdd');
});
