That error occurs when the object, in this case the video, hasn't loaded enough to be able to set the currentTimeand skip forward.
当对象（在本例中为视频）尚未加载到足以设置currentTime和 向前跳过时，就会发生该错误。
You'd have to wait until the video can be played before you can set the currentTime
您必须等到视频可以播放后才能设置 currentTime
var myVideo = document.getElementById('myVideo')
myVideo.addEventListener('canplaythrough', function() {
myVideo.currentTime = 570;
}, false);
