更改rangelider的起点videojs
我在我的反应应用程序中使用videojs。我已经添加了rangelider。我的视频播放器附近有一个按钮，可以触发测距播放器显示在视频播放器上。一切都运行正常，但是rangelider的起始箭头不在我点击按钮的点（时间）。开始按钮始终为0：0。我想要的是：说视频在当前时间30:00播放，然后我点击了显示按钮，然后测距应该只在30秒显示它的起始箭头而不是在o秒。我可以获取videojs播放器的当前时间并将其传递给rangeslider.js插件，但我不知道将它传递到何处。
这是我的rangelider.js（我知道它是一个很长的代码，但我不知道它的哪一部分用来实现结果）
