Fullcalendar：如何删除事件

Question

Thanks to another post here on StackOverflow, I added some code to my select: method that prevents users from adding an event on a date prior to NOW.

The downside is that when they click on the empty time slot, and the system then complains (an alert message), the attempted event remains. How do I get rid of it? Thanks!

Update: Here's my code:

    select: function(start, end, jsEvent) {

        var check = start._d.toJSON().slice(0,10),
            today = new Date().toJSON().slice(0,10),
            m = moment(),
            url = "[redacted]",
            result = {};
            title = "Class",
            eventData = {
                title: title,
                start: start,
                end: start.clone().add(2, 'hour'),
                durationEditable: false,
                instructorid: 123,
                locationid: 234
            };


        if(check < today) {
            alert("Cannot create an event before today.");

            $("#calendar").fullCalendar('removeEvents', function(eventObject) {
                return true;
            });

        } else {

            $.ajax({ type: "post", url: url, data: JSON.stringify(eventData), dataType: 'JSON', contentType: "application/json", success: function(result) {

                if ( result.SUCCESS == true ) {
                    $('#calendar').fullCalendar('renderEvent', eventData, true);
                    $('#calendar').fullCalendar('unselect');

                } else {

                    alert(result.MESSAGE);
                }

            }});
        }
    }

Answer 1

If you're using FullCalendar V2, you need to use the removeEvents method .

You can use it to delete events with a certain ID by calling it in this way:

$("#calendar").fullCalendar('removeEvents', 123); //replace 123 with reference to a real ID

If you want to use your own function that decides whether or not an event get's removed, you can call it this way:

$("#calendar").fullCalendar('removeEvents', function(eventObject) {
    //return true if the event 'eventObject' needs to be removed, return false if it doesn't
});

FullCalendar has a removeEvent method that uses an id when you create the event.

Example Full Calendar v1:

var calendar = $('#calendar').fullCalendar({ ... stuff ... });
    calendar.fullCalendar( 'addEventSource', {id:123, stuff:'stuff'});
    // ... other calendar things here...
    calendar.fullCalendar( 'removeEvent', 123);

Reference API v1

Example FullCalendar v2:

var calendar = $('#calendar').fullCalendar({ ... stuff ... });
    calendar.fullCalendar( 'addEventSource', {id:123, stuff:'stuff'});
    // ... other calendar things here...
    calendar.fullCalendar( 'removeEvents', [123]);

                    alert(info.event.title);

                },
                eventDrop : function(info) {
                    alert(info.event.title + " was dropped on "
                            + info.event.start.toISOString());

                    if (!confirm("Are you sure about this change?")) {
                        info.revert();
                    }
                },
                eventClick : function(info) {
                     //delete event from calender
                    info.event.remove();

                }

            });

            calendar.render();
        });

How to remove event from calendar:

<div id="calendar"></div>

<script>
document.addEventListener('DOMContentLoaded', function() {
    var calendarEl = document.getElementById('calendar');
    var calendar = new Calendar(calendarEl, {
      events: [
        {
          id: '505',
          title: 'My Event',
          start: '2010-01-01',
          url: 'http://google.com/'
        }
        // other events here
      ],
      eventClick: function(info) {
        info.jsEvent.preventDefault(); // don't let the browser navigate

        if (info.event.id) {
            var event = calendar.getEventById(info.event.id);
            event.remove();
        }
      }
    });
});
</script>

This worked for me. I hope, this will also help you. Thanks for asking this question.
