FullCalendar v3 - 在视图更改时更改事件源

Question

我正在使用带有 PHP 后端的 FullCalendar v3（最新）。

我从后端返回一个 JSON 数组，分成 2 个数组。第一个包含事件详细信息（当天的订单列表，以订单号作为标题），第二个包含每日摘要（以订单和工作时间的总和作为标题）。该数组如下所示：

{"events":[{"id":709989,"item_no":"ABC123","title":709989,"color":"red","start":"2019-05-14","end":"2019-05-14","allDay":true,"total_hours":3,"remaining_hours":1.5},{"id":709990,"title":709990,"item_no":"ABC345","color":"red","start":"2019-05-15","end":"2019-05-15","allDay":true,"total_hours":5.7,"remaining_hours":3.2}],"summary":[{"id":338823,"title":"Orders: 14\rHours:28.33\rRemaining Hours:13.33","start":"2019-05-14","end":"2019-05-14","allDay":true},{"id":338824,"title":"Orders: 3\rHours:14.2\rRemaining Hours: 12.2","start":"2019-05-15","end":"2019-05-15","allDay":true}]}

还有其他属性，但这些是基础。

我想做的是根据选择的视图更改用作事件源的数组。我已经尝试过自定义事件呈现、自定义视图呈现、多个事件源（尽管它从数据 point-of-view 来说很昂贵，但记录的数量并没有多到对性能有很大影响）。

自定义视图名称是 customMonth。选择此视图后，我只想呈现摘要数据（来自摘要数组）。如果选择了任何其他视图（我使用的是 basicWeek、month 和 listWeek），则呈现事件数组。

let vname;
$("#calendar").fullCalendar({
    defaultDate: new Date(),
    defaultView: 'month',
    eventRender: function(eventObj, $el, view) {
        let n = view.name;
        if(n=='customMonth')
        {
            vname = 'customMonth';
            $el.popover({
                title: eventObj.title,
                content: eventObj.total_hours,
                html: true,
                trigger: 'hover',
                placement: 'auto',
                container: 'body'
            });
        } else {
            vname = n;
            $el.popover({
                title: "Work Order " + eventObj.title,
                content: '<strong>Item#</strong>: ' + eventObj.item_no + '<br />' + '<strong>Total Hours</strong>: ' + eventObj.total_hours + '<br />' + '<strong>Remaining Hours</strong>: ' + eventObj.remaining_hours,
                html: true,
                trigger: 'hover',
                placement: 'auto',
                container: 'body'
            });
        }
    }, 
    events: function(start, end, timezone, callback){
        $.ajax({
            url: '/myendpoint',
            type: 'POST',
            dataType: 'json',
            data: {
                action: 'get-calendar-summary',
                cell: selected_cell
            },
            success: function(data) {
                let events = [];
                if(vname=='customMonth') {
                    obj = data.summary;
                    $(obj).each(function() {
                        events.push({
                            id: $(this).attr('id'),
                            title: $(this).attr('title'),

                            allDay: true,
                            earliest_date: $(this).attr('earliest_date')
                        });
                    });
                } else {
                    obj = data.event_results;
                    $(obj).each(function() {
                        events.push({
                            id: $(this).attr('id'),

                            start: $(this).attr('start'),
                            end: $(this).attr('end'),

                    });
                }

            },
            error: function(err) {
                console.log(err);
            }
        });
    },
    views: {
        customMonth: {
            type: 'month',

            if(lastview == 'customMonth') {
                return false;

                view.renderDates();
                $("#calendar").fullCalendar('rerenderEvents');
            }
            lastview = 'customMonth';
        } else {
            if(lastview=='customMonth') {
                view.unrenderDates();
                view.renderDates();

            }
            lastview = view.name;

    },
    header: {
        left: 'prev,next',
        center: 'title',
        right: 'basicWeek,month,listWeek,customMonth'
    },
    themeSystem: 'bootstrap3',
    timeZone: false,
    weekends: false,
    //tried with and without lazyFetching
    lazyFetching: true
});

如有任何指导，我将不胜感激。我搜索了 Whosebug（this seems like the closest，但我完全按照它做了，但它没有用（将 viewDisplay 切换为 viewRender）），Github，以及我能想到的所有其他来源。

这里是您要实现的目标的简化示例（希望我能很好地理解您的问题）：

HTML :

 <div id='calendar'></div>

Javascript :

$(document).ready(function() {
    var ev1 = {"events":[{"id":709989,"item_no":"ABC123","title":'Event from source 1',"color":"red","start":"2019-05-14","end":"2019-05-14","allDay":true,"total_hours":3,"remaining_hours":1.5}]};
    var ev2 = {"events":[{"id":709989,"item_no":"ABC123","title":'Event from source 2',"color":"blue","start":"2019-05-14","end":"2019-05-14","allDay":true,"total_hours":3,"remaining_hours":1.5}]};
    $('#calendar').fullCalendar({
        defaultDate: new Date(),
        defaultView: 'month',
        viewRender: function(view) {
          if(view.type === 'basicWeek') {
             $('#calendar').fullCalendar( 'removeEventSource', ev1 );
             $('#calendar').fullCalendar( 'addEventSource', ev2 );
             return; 
           }  
        },
        header: {
           left: 'prev,next',
           center: 'title',
           right: 'basicWeek,month,listWeek,customMonth'
        },

    });
    $('#calendar').fullCalendar( 'addEventSource', ev1 );  
});

然后codepen试试看。

它使用回调函数 viewRender() 来检测视图何时更改，并使用 addEventSource()/removeEventSource() 来更改数据。因此，当您将视图从 month 更改为 week 时，它会更改源事件。
