$('#calendar').fullCalendar({
    events: function(start,end, callback) {
        $.ajax({
            url:'myxmlfeed.php',
            dataType: 'xml',
            data: {
                // ourhypothetical feed requires UNIX timestamps
                start:Math.round(start.getTime() / 1000),
                end: Math.round(end.getTime()/ 1000)
            },
            success:function(doc) {
                var events =[];
               $(doc).find('event').each(function() {
                   events.push({
                        title:$(this).attr('title'),
                        start:$(this).attr('start') // will be parsed
                    });
                });
               callback(events);
            }
        });
    }
});
它这里的 dataType :XML 我不太了解,  我不知道用什么方式将数据读出来, 然后循环到 里面..
