Bootstrap Fullcalendar addClass在弹出窗口中

Question

我只想为bootstrap fullcalendar popover添加类名。我在很多地方在下面的脚本中尝试过$(".popover").addClass('fc-ctpopover');。它不适用于此代码。

评论以进一步澄清。

$（“。popover”）。addClass（'fc-ctpopover'）;

我的预期输出<div class="popover fc-ctpopover">

$(document).ready(function() {

    var date = new Date();
    var d = date.getDate();
    var m = date.getMonth();
    var y = date.getFullYear();
    var calendar = $('#calendar').fullCalendar({
        header: {
            left: 'prev,next today',
            center: 'title',
            right: 'month,agendaWeek,agendaDay'
        },
        height: 600,
        selectable: true,
        selectHelper: true,

        select: function(start, end, allDay) {
