使用codeigniter进行Jquery fullcalendar CRUD操作

Question

我使用fullcalendar插件坚持使用CRUD操作。我可以在数据库中插入值，但是我在从数据库中检索数据时遇到了一些困难，因为我想在日历上显示记录。 我尝试使用eventClick，eventDrop来更新和删除事件（记录）但尚未成功。 任何帮助或指导将不胜感激.... 请注意：我已经在autoload.php中包含了必要的条款。

代码：（JavaScript的，AJAX）

$(document).ready(function() {
    var date = new Date();
    var d = date.getDate();
    var m = date.getMonth();
    var y = date.getFullYear();

    var calendar = $('#calendar').fullCalendar({
                     editable: true,
                     header: {
                          left: 'prev,next today',
                          center: 'title',
                          right: 'month,agendaWeek,agendaDay'
                         },

                     events:"PersonalCalendar/loadEvents",

                                selectable: true,
                                selectHelper: true,
                                select: function(start, end) {
                                var title = prompt('Event Title:');
                                var desc = prompt('Event description:');
                                if (title) {
                                var start = $.fullCalendar.formatDate(start, "yyyy-MM-dd");
