使用 fullCalendar,我允许用户在大日历 (#cal_big) 中选择月 View 中的一天,并在日 View 中选择相应的小日历,并显示小时 (#cal_small)。
每当用户在 #cal_small 中选择一个事件(一小时或几小时)时,我都会显示确认/取消模式。确认/取消模式允许用户确认预订或取消预订(这在语义上意味着用户毕竟不想预订该时段)。
如果用户确认预订,我会向服务器发出 ajax 调用并注册预订。一旦 ajax 调用成功返回,我只需隐藏当前模式并显示“您的预订成功!”以新模式发送消息。这部分工作完美无缺。
如果用户取消预订,确认/取消模式将被隐藏,我尝试以编程方式取消选择当前选择,这就是问题开始的地方。取消选择不起作用,似乎 fullCalendar 会记住所有这些未确认的选择,当用户最终确认他的选择时,一大堆先前未确认的选择都会在多个 ajax 调用中重复发送到服务器。
为什么会这样?如何防止 fullCalendar 记住未经确认的选择?
这是代码:-
$(document).ready(function() {
var todayDate = new Date();
var myDate = todayDate.setDate(todayDate.getDate() - 1);
var csrfmiddlewaretoken = '{{ csrf_token }}';
var condo_slug = '{{ condo.slug }}';
var facility = $("#id_facility");
var cal_small_options = {
titleFormat: {
day: 'dddd'
},
header: {
left: '',
center:'title',
right:'',
},
height: 520,
defaultView: 'agendaDay',
editable: true,
minTime: '10:00',
maxTime: '23:00',
slotMinutes: 60,
selectable: true,
select: function(startDate, endDate, allDay, jsEvent, view) {
console.log("selection triggered", jsEvent.handleObj.guid)
checkAvailability(csrfmiddlewaretoken, condo_slug, facility, startDate, endDate);
$('#confirm').click(function(){
confirmBooking(csrfmiddlewaretoken, condo_slug, facility.val(), startDate, endDate)
});
},
events: function(start, end, callback) {
// start and end marks the current date range shown on the calendar
ajaxShowEvents(facility.val(), condo_slug, start, end, callback);
},
eventClick: function(event) {
console.log(event.title);
},
viewDisplay: function(view) {
// Clear the calendar and retrieve event objects when user selects a facility.
$('#id_facility').change(function(){
ajaxShowEvents(facility_id = $(this).val(), start = view.start, end = view.end);
});
}
};
var cal_big_options = {
header: {
left: '',
center:'title',
right: ''
},
dayClick: function(date, allDay, jsEvent, view) {
if (date < myDate) {
alert('You cannot book on this day!');
}
if (allDay) {
$('#cal_small').fullCalendar('gotoDate', date);
} else {
alert('Clicked on the slot: ' + date);
}
},
selectable: true,
unselectCancel: '',
events: function(start, end, callback) {
// start and end marks the current date range shown on the calendar
ajaxShowEvents(facility.val(), condo_slug, start, end, callback);
},
viewDisplay: function(view) {
// Clear the calendar and retrieve event objects when user selects a facility.
$('#id_facility').change(function(){
ajaxShowEvents(facility_id = $(this).val(), start = view.start, end = view.end);
});
},
eventClick: function(event, jsEvent, view) {
if(event.start < myDate) {
alert('You cannot book on this day!');
} else {
// check to see if the booking belongs to user
ajaxCheckBooking(csrfmiddlewaretoken, event);
$('#confirm').click(function(){
ajaxDeleteBooking(csrfmiddlewaretoken, event)
});
}
}
};
$('#cal_small').fullCalendar(cal_small_options);
$('#cal_big').fullCalendar(cal_big_options);
$('.cancel, .btn_close').click(function() {
$('#cal_big, #cal_small').fullCalendar('unselect')
$('#modal-window').modal('hide');
});
}); // END document ready
更新
按要求确认预订功能:-
function confirmBooking(csrfmiddlewaretoken, condo_slug, facility_id, startDate, endDate) {
// Given condo slug, facility id and the user selected startDate and endDate,
// send an ajax post request to confirm the booking
post_data = {csrfmiddlewaretoken: csrfmiddlewaretoken,
condo_slug: condo_slug,
facility_id: facility_id,
start_date: startDate.toUTCString(),
end_date: endDate.toUTCString()}
$.ajax({
url: '/facility/ajax-confirm-booking/',
data: post_data,
type: 'POST',
dataType: 'json',
success: function(data) {
if (data['status']=='success') {
message = "Your booking is confirmed!"
event = new Object();
event.id = data['id'];
event.title = "Your Booked Event";
event.start = startDate;
event.end = endDate;
event.allDay = false;
$("#cal_big").fullCalendar('renderEvent', event);
$("#cal_small").fullCalendar('renderEvent', event);
// TODO:
// * disable the submit and reset buttons
// * email notification to end user and property manager
} else if (data['status']=='not logged in') {
message = "You are not yet logged in!"
// TODO:
// * Provide fb login button so user can login.
} else {
message = "I am sorry. Something went wrong with your booking"
// TODO:
// * Work on an email notification to site admin if a booking has failed for some reason
}
displayModal(message, false);
}
});
}; // END confirmBooking
如果有人能详细说明为什么 .fullCalendar('unselect') 调用无法删除未经确认的事件以及我如何解决此问题,我们将不胜感激。
最佳答案
解决了。
这是一个非常简单的错误,我完全错过了。
select: function(startDate, endDate, allDay, jsEvent, view) {
console.log("selection triggered", jsEvent.handleObj.guid)
checkAvailability(csrfmiddlewaretoken, condo_slug, facility, startDate, endDate);
$('#confirm').click(function(){
confirmBooking(csrfmiddlewaretoken, condo_slug, facility.val(), startDate, endDate)
});
},
每次在日历上选择一个事件时,都会将单击事件绑定(bind)到#confirm
按钮。因此,如果用户不断选择事件而不确认,#confirm
按钮将不断累积具有不同 startDate 和 endDate 的不同点击事件。当用户在反复犹豫不决后最终点击 #confirm
按钮时,所有点击事件都会一次性触发,导致之前未选择的事件作为 ajax post 发送到服务器。
要解决这个问题,我必须记住在用户单击 .cancel
或 时指定
按钮。$('#confirm').unbind()
。关闭
啊...一个简单的解决方案,但我花了很长时间才看到它!
关于jquery - fullCalendar 1.5.3 创建了多个事件,无法删除未选定的事件,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/9652789/
