我正在开发跨浏览器 HTML5 视频应用程序。我开始尝试 videojs为了技术上的可能性，我用 videojs 开发了一个页面，它在所有浏览器中都能正常工作，但在 IE9 及以上版本中它不起作用。如果它有效，它正在使用 swf 加载视频，而不是使用 HTML5 播放器。
这是我的代码

所有资源均已正确加载，并且可以在除 IE9 及更高版本之外的所有浏览器中运行。
请帮我看看我哪里出错了。

您获得了 HTML5 Shiv 吗？听起来这就是你所缺少的。
关于javascript - Videojs 无法在 IE 9 及更高版本中工作，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22067687/
