我有一个动态的视频库,它在计算机上运行良好.移动到iPad时,视频开始加载,并显示无法播放的图标.而不是这个,我宁愿视频不显示,直到它准备好播放.我试图为"canplaythrough"和"canplay"添加事件监听器,当它们出现时,视频会淡入然后播放.iPad不支持这些活动吗？

new_video = document.createElement('video');
new_video.setAttribute('class', 'none');
new_video.setAttribute('width', '568');
new_video.setAttribute('height', '269');
new_video.setAttribute('id', 'video'+video_num);
current_video.insertBefore(new_video, video_controls);
new_video.load();
new_video.addEventListener('canplaythrough', function() {
     $('#video'+video_num').fadeIn(100);
     new_video.play();
});
