javascript - InvalidStateError : An attempt was made to use an object that is not, 或不再可用

Question

以下适用于 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 中它说

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)加载不足，无法设置 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);
