Why are you overwriting getDateFormat? You're not supposed to do that - by default it gets the timestamp format that your database type uses.

            在console里面输入以下代码来设置播放速度(默认为1), n 你为想要的值:
var video = $('video')[0];
video.playbackRate = n;
                var video = $('video')[0];
video.playbackRate = n;
