Iframe / Javascript Check if Youtube Video Ends
提问by Howdy_McGee
Right now I have youtube videos loading in via Iframe. Is it even possible to check if the youtube video ended when it is in that sort of state? Can I use OnStateChange() through the Iframe?
现在我通过 iframe 加载了 youtube 视频。甚至可以检查 YouTube 视频在这种状态下是否结束？我可以通过 Iframe 使用 OnStateChange() 吗？

you can detect the end of the video like so:
您可以像这样检测视频的结尾：
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.ENDED){
// your code to run after video has ended
}
}

If you have an iframeon your page, and its srcattribute contains a URL which does not have the same domain, protocol or port as the container page, you can not access its documentbecause of Same Origin Policy.
如果您有iframe您的网页上，它的src属性包含不具有相同的域，协议或端口作为容器页面的URL，你不能访问它document的，因为同源策略。
You may want to look into YouTube supporting postMessage().
您可能需要查看 YouTube 支持postMessage().
If you do own the iframe's contents, then get its iframe.contentDocumentwhere you can access the iframe's document.
如果您确实拥有iframe's 的内容，那么请iframe.contentDocument在您可以访问iframe's 的地方获取它document。
