全天，多天事件被移动到日历上的错误日期以供日查看

Question

Event : 产品预订定于3月9日开始，11日结束，但日历显示为提前一天结束日视图网格。但是用周网格视图显示全天没有问题。我附上了屏幕截图以供参考。你能帮忙吗？

                    eventDataTransform: function (eventData) {                    
                    console.log('EventDataStart-->'+eventData.start);
                    console.log('EventDataEnd-->'+eventData.end);
                    /*var m = moment(eventData.end);
                    var roundDown = m.startOf('day');
                    var day2 = moment(roundDown).add(1, 'days')
                    eventData.end = day2.toString();
                    console.log('EventDataEndAfter-->'+eventData.end);*/
                    var dur = eventData.end - eventData.start; //total event duration

                    if(dur >= 18000000 || eventData.end == null){ // 5 hours

                            eventData.allDay = true;
                            eventData.allDaySlot = true;

                            console.log('dur-->'+dur);
                            //eventData.end needs ammending to 00:00:00 of the next morning
                            if (dur > 86400000) {


                            var m = moment(eventData.end);
                            var roundDown = m.startOf('day');
                            var day2 = moment(roundDown).add(1, 'days')

                            eventData.end = day2.toString();
                            console.log('EventDataEndIf1-->'+eventData.end);
                            }

                    }
                    console.log('eventData-->'+JSON.stringify(eventData));
                    return(eventData);  
                }

以前在添加一天之前（参考代码）它用于显示周网格和天网格的一天。将一天添加到结束日期后，它在周网格上正确显示，但在天网格上不正确。 预期结果：订单应在日网格日历视图中正确显示并具有正确的结束日期。
