问题描述
我正在尝试与Chrome中的第三方html5视频播放器进行互动。我能够获得对它的有效引用：
I am trying to interact with a 3rd-party html5 video player in Chrome. I am able to obtain a valid reference to it thusly:
document.getElementsByTagName("video")[1]
...而 readyState 是4，所以它是好的。
...and the readyState is 4, so it's all good.
我可以成功（并且有预期的结果）致电：
I can successfully (and with expected result) call:
document.getElementsByTagName("video")[1].play();
document.getElementsByTagName("video")[1].pause();
但是当我打电话时：
document.getElementsByTagName("video")[1].currentTime = 500;
...视频冻结，并且没有前进到新的 currentTime的。视频持续时间远远超过500秒，因此它应该能够前进到那个位置。我已尝试过500次以外的其他时间，都有相同的结果。如果我检查 currentTime ，那么我刚设置的是正确的。但它实际上并没有去那里。此外，我无法再与视频互动。它在我尝试设置 currentTime后忽略对。 play（）或 pause（）的任何调用
...the video freezes and it doesn't advance to the new currentTime. The video duration is much longer than 500 seconds, so it should be able to advance to that spot. I have tried other times besides 500, all with same result. If I examine currentTime, it is correct as to what I just set. But it doesn't actually go there. Also I can no longer interact with the video. It ignores any calls to play() or pause() after I try to set currentTime.
之前我拨打 currentTime ，当我打电话给 play（）我得到了这个有效的保证，其他一切仍然有效：
Before I call currentTime, when I call play() I get this valid promise back, and everything else still works:
之后我拨打 currentTime ，当我拨打 play（），我得到了这个破碎的承诺，现在该视频对象无效：
After I call currentTime, when I call play(), I get this broken promise back, and now nothing works on that video object:
如果您有一个帐户，只需在Chrome开发者控制台中尝试，您就可以轻松地在任何视频中观察此行为
If you have a Hulu account you can easily observe this behavior on any video by simply trying it in the Chrome developer console.
编辑：有人向我指出，跳过很长时间的休息时间，但跳过短距离确实很有效。可能与穿插的商业广告有关。
EDIT: It was pointed out to me that skipping very much ahead breaks, but skipping a short distance actually works well. Could be related to commercials interspersed.
推荐答案
尝试下面的代码，它会先暂停然后再设置你的位置然后再玩
Try below code, it will first pause then set your position then again play
document.getElementsByTagName("video")[1].pause();
document.getElementsByTagName("video")[1].currentTime = 500;
document.getElementsByTagName("video")[1].play();
