根据完整日历的开始和结束日期限制数据访问

新日历的初学者 我想从数据库中检索完整日历的事件，但我想限制或限制屏幕上显示的特定日期范围的数据

对于检索事件，我需要将屏幕上选择的开始日期和结束日期传递给通用处理程序，即 NewJosn.ashx

我使用的示例代码是：

var calendar = $('#calendar').fullCalendar({
    theme: true,
    height: calHeight,
    allDaySlot: false,
    disableDragging: false,
    defaultView: 'agendaWeek',
    slotEventOverlap: false,
    slotMinutes: varTimeSlot,
    firstHour: startTimeNew,
    firstDay: varFirstDay,
    header: {
        left: '',
        center: 'prev,today,title,next',
        right: 'resourceDay,agendaWeek,month' //resourceDay
    },
    timeFormat: 'h(:mm)tt{ - h(:mm)}tt',
    axisFormat: 'h(:mm)tt',
    editable: true,
    events: 'NewJSON.ashx',
    eventDrop: eventDropped,
    eventClick: function (calEvent, jsEvent, view) {
    },
    viewDisplay: function (view) {   
    },
    eventMouseover: function (event, jsEvent, view) {
            $(jsEvent.target).attr('title', event.title);
    },
    eventMouseout: function (event, jsEvent, view) {
    },
    dayClick: function (date, allDay, jsEvent, view) {
    },
    eventAfterRender: function (event, element, view) {
    },
    resources: [
                {
                    name: 'Resource 1',
                    id: '1'
                },
                {
                    name: 'Resource 2',
                    id: '2'
                },
                {
                    name: 'Resource 3',
                    id: '3'
                },
                {
                    name: 'Resource 4',
                    id: '4'
                }
    ]
});
