How to edit Title in Fullcalendar

问题

I'm trying to use the fullcalendar library in ServiceNow and everything seems to be working fine, but there's something weird going on with the Title:

Is there a way to get rid the undefinedundefined by making changes to the Title object? My current code is pretty simple:

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

I think you have used different version of full calendar css and js file. in this it works fine. please check your file version used. i hope it should be helps you

$(document).ready(function() {

        // page is now ready, initialize the calendar...

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