Question

我希望添加号召性用语按钮，这些按钮仅在播放视频时在特定时间参数期间出现。我目前正在使用javascript，它工作正常但是当我为视频添加超过1时，只有一个有效。

它在某种程度上起作用，但是当一个视频添加了多个时，一个将无法正常工作。

以下是关于jsfiddle的代码：https://jsfiddle.net/ktdonohoe/cnma4s6b/

视频在那里不起作用，但基本上按钮应该出现在每个视频的某个时间范围内，如下所示：

我根据2011年发现的一篇文章https://www.smashingmagazine.com/2011/03/syncing-content-with-html5-video/

来做这件事

我想知道是否有更新的方法来执行此操作，或者是否有人知道解决此问题的方法。

使用HTML5视频同步内容
