完整日历 columnFormat 导致 object object

Full Calendar columnFormat leads to object object

我正在尝试更改 agendaWeek 中的列标题以仅显示日期,例如星期一,而不是 5 月 7 日星期一。但是,当我尝试进行任何更改时,列标题变为 object object.Here's a screenshot.

我使用的是 FullCalendar 3.4.0 版和 jquery 2.1.1。 这是我的代码片段:

$(document).ready(function() {

    $('#calendar').fullCalendar({
        header: false,
        defaultView: "agendaWeek",
        defaultDate: '2017-05-12',

        views: {
            agenda: {
                columnFormat: {
                month: 'dddd',    // Monday, Wednesday, etc
                week: 'dddd, MMM dS', // Monday 9/7
                day: 'dddd, MMM dS'  // Monday 9/7
            }
                // options apply to agendaWeek and agendaDay views
            }
        },
        navLinks: true, // can click day/week names to navigate views
        selectable: true,
        selectHelper: true,
        select: function(start, end) {
            var title = prompt('Event Title:');
            var eventData;
            if (title) {
                eventData = {
                    title: title,
                    start: start,
                    end: end
                };
                $('#calendar').fullCalendar('renderEvent', eventData, true); // stick? = true
            }
            $('#calendar').fullCalendar('unselect');
        },
        editable: true,
        eventLimit: true, // allow "more" link when too many events

尝试像这样在视图议程下设置 slotLabelFormat

views: {
    agenda: {
        slotLabelFormat: 'ddd',
    }
}
