How I can delete event using event's date in fullcalendar

Question

I try to delete an event using event's date. I see in documentation like the following

idOrFilter may also be a filter function that accepts one Event Object argument and returns true if it should be removed.

So, I just try like the following

$('#calendar').fullCalendar('removeEvents', event.start);

It's no difference with removing with id.

Why I try to remove using event date is I have an event and it can be drag and drop to the calendar's difference date. Like this example . And I just want to delete event from specific date. But now it's just removing all the events. I appreciate all of helps.

Answer 1

You need to specify the ID of the event object that you want to remove.

$('#calendar').fullCalendar('removeEvents', "ID");

If you do not specify any ids, it will simply remove all events.
