Question

我正在使用全日历，我要做的是当用户单击事件时，然后询问用户是否要延长课程时间。如果用户之前取消了课程（在我的数据库中），那么用户可以将课程时间延长15分钟。因此，如果用户可以扩展该类，则可以使用ajax和php将信息发送到mysqlDB。但是，问题是所有信息（正确的是endDate，startDate和canceledCourseDate，以及end（在扩展之前的endDate））都正确地发送到了ajax，但出现错误。

未捕获的TypeError：无法读取未定义的属性'_calendar'

因此，我搜索了一些信息，并添加了.format（“ YYYY-MM_DD HH：mm”），但仍然有问题。

这是js代码

            var canceledList = <?php echo $json_array4; ?>; //not newlyBooked canceled Date List
            var canceledListNum = canceledList.length;
            var extensionList = <?php echo $json_array10; ?>;
            var extendedListNum = extensionList.length;
            var canceledDate = '';
            var extensionStatus = 'going';
            if(extendedListNum > 0)
            {
                canceledDate = extensionList[0]['canceledCourseDate']; //get canceledDate that is alreay in extension
            }
            else if(canceledListNum > 0)
            {
                canceledDate = canceledList[0]['canceledCourseDate']; //if there is no course that is in extension, then get new canceledDate that isn't done yet.
                extensionStatus = 'new';
            }




            var id = calEvent.id;
            var teacher = calEvent.resourceId;



            var extendedDate = moment(calEvent.start.format("YYYY-MM-DD HH:mm"));
            var end = moment(calEvent.end.format("YYYY-MM-DD HH:mm"));
            var endDate = moment(end).add(15, 'minutes');

            console.log(start);
            console.log(extendedDate);
            console.log(end);
            console.log(endDate);
            console.log(canceledDate);


            var limit = 2;
            var userDuration = '<?php echo $userDuration; ?>';

            if(userDuration == '60')
            {
                limit = 4;
            }


            if(id == '<?php echo $userID; ?>')
            {


            }
            else // extend lesson 
            {   
                    if(new Date(start) < new Date(today))
                    {
                        alert("cannot extend the class");

                    }
                    else{
                        if(canceledDate == '')
                        {
                            alert("cannot extend the class");
                        }else
                        {
                            $.ajax({
                               url:"extend.php",
                               type:"POST",
                               data:{userName: '<?php echo $name; ?>' , canceledCourseDate: canceledDate, extendedDate: extendedDate , endDate: endDate ,courseTeacher : teacher, userBranch:'<?php echo $userBranch; ?>', userID: '<?php echo $userID; ?>', duration : '<?php echo $userDuration; ?>', originalEnd : end, extensionStatus: extensionStatus},
                               success:function(response)
                               {
                                    console.log(response);
                                    $("#calendar").fullCalendar('refetchEvents');
                                    alert("Successfully extended.");
                                    location.reload();
                               }
                              });
                        }
                    }
                }
            }

Answer 1

var end = moment(calEvent.end.format("YYYY-MM-DD HH:mm"));

这不起作用。但是，

var endDateForAdd = moment(endDate).format("YYYY-MM-DD HH:mm");

这有效。
