我正在制作一个带有自定义控件的 HTML5 视频/音频播放列表播放器。
我有适用于单个视频的自定义控件，但我无法将这些控件和 currentTime/duration 属性绑定到用户可能单击的每个视频上。
这是一个显示我的意思的jsfiddle 。
代码也在这个问题的底部。请不要害怕，JS 底部 90% 是自定义控件。前 10% 是定义视频对象和on单击功能以选择所需的视频。
我已将默认设置为播放 3 个中的“视频 2”。自定义控件确实控制“视频 2”。按钮切换每个视频的播放/暂停，但您会注意到自定义控件仍控制“视频 2”，无论单击哪个按钮。
基本上，我只需要找到一种方法，当您单击每个视频按钮时，所有控件和属性（currentTime，duration）都会绑定到所选视频。
