FullCalendar跨域JSON无法正常工作

Question

我已尝试过在StackOverFlow上发布的几乎所有解决方案，但似乎无法让它适用于跨域JSON响应

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

            selectable: true,
            editable: false,
            eventSources: [
            {
                url: 'http://www.demo.com/feed'
            }
            ],
            eventDrop: function(event, delta) {
            alert(event.title + ' was moved ' + delta + ' days\n' +
                '(should probably update your database)');
        },
        loading: function(bool) {
            if (bool) $('#loading').show();
            else $('#loading').hide();
        }
        });

    });

有没有人让它顺利运作？

干杯
