InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable

Question

以下内容适用于 Chrome 但不适用于 Firefox：

var myVideo = document.getElementById('myVideo')
myVideo.currentTime = 570

<video id="myVideo" controls>
<source src="myVideo.mp4" type="video/mp4">
</video>

在 Firefox 中显示

InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable

第 2 行。

Answer 1

当对象（在本例中为视频）的加载量不足以设置 currentTime 并向前跳时，就会发生该错误。

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);
