Is there a way to "seek" to a certain time in a video using JavaScript?
提问by Sheehan Alam
I have an iframe with a video, for example:
我有一个带有视频的 iframe，例如：
<iframe src="http://player.vimeo.com/video/18150336" width="500" height="281" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>
The source won't always be vimeo, it can be YouTube, BrightCove, Hulu etc etc.
来源并不总是 vimeo，可以是 YouTube、BrightCove、Hulu 等。
Is there a way to use jQuery/JavaScript to "seek" to a certain time in the video? For example, if I wanted to get to 3:41 inside of a video could I write code to automatically seek to that time w/o API access to the sites providing the video?
有没有办法使用 jQuery/JavaScript 来“寻找”视频中的某个时间？例如，如果我想到达视频中的 3:41，我可以编写代码来自动寻找那个时间，而无需 API 访问提供视频的网站吗？

Sure. You can use VideoJS. You may have a hard time getting control of the iFrame as you put it. You can embed various video hosting sites' video with VideoJS, supposedly.
当然。您可以使用 VideoJS。正如您所说的那样，您可能很难控制 iFrame。据说，您可以使用 VideoJS 嵌入各种视频托管网站的视频。
<script>
VideoJS.DOMReady(function() {
var player = VideoJS.setup("current_video");
player.play();
player.currentTime(666);
});
</script>

Unless your website also has the host, protocol and port of http://player.vimeo.com, you can not run any code on the iframe's document.
除非你的网站也有主机，协议和端口http://player.vimeo.com，您不能在运行任何代码iframe的document。

Unfortunately, not always. There is no single solution to seek a time in a Flashvideo if you don't know what the source of the video is.
不幸的是，并非总是如此。如果您不知道视频的来源是什么，则没有单一的解决方案可以在Flash视频中寻找时间。
If you ever encounter HTML5 video, you can try this: Start HTML5 video at a particular position when loading?
如果你遇到过 HTML5 视频，你可以试试这个：加载时在特定位置启动 HTML5 视频？

That iframe will give you trouble, however in general you can do this without a library.
该 iframe 会给您带来麻烦，但通常您可以在没有库的情况下执行此操作。
// get the video element
let video = document.getElementsByTagName('video')[0]
// jump it to a specific time
video.currentTime = 10 // the number of seconds you want it to be at
