您可以使用Ajax获取数据，然后动态添加新源

$.ajax({
  url: "test.html",
  success: function(data){
       var source = { events: [
                            {
                                title: data.getTitle(),
                                start: new Date(year, month, day)
                            }
                ]};
                $('#calendar').fullCalendar( 'addEventSource', source );
  }
});
