完整的日历事件出现两次

Question

创建事件后，样式仍然保留。但是有时事件似乎是重复的。随附了jquery代码和屏幕截图，以便于更好地理解。

这是从后端加载后事件的外观

这是我的jquery函数

select: function (start, end) {
                        var title = "Available";
                        var eventData;
                        if (title) {
                            eventData = {
                                title: title,
                                start: start,
                                end: end
                            };
                            $('#calendar').fullCalendar('renderEvent', eventData, true); // stick? = true

                            createEvent(eventData);

                            window.setTimeout(function () {
                                location.reload()
                            }, 300);

                            $.notifyBar({
                                cssClass: "WARNING",
                                html: "Created Successfully."
                            });
                        }
                        $('#calendar').fullCalendar('unselect');

                    },
