这里是 JavaScript 初学者!

我正在尝试静音/取消静音和暂停/取消暂停音频和视频，但我不知道该怎么做。

我希望按钮在单击时使音频静音/取消静音，并在我单击另一个按钮时暂停/取消暂停本地视频。这是完整的 javascript 代码。

现在请编辑它并解决问题。

此处为 Twilio 开发人员布道师。

您没有包含实际设置调用的代码位，因此我只能为您指出正确的方向。

当您加入一个房间时，可以从房间中的 localParticipant 对象访问您的本地媒体。 localParticpant 是 Participant 的一个实例，因此您可以调用它们的 audioTracks 或 videoTracks，它们都实现了 LocalTrack , 当你想要的时候。

如果你想静音，例如，你可以调用

room.localParticipant.audioTracks.forEach(function(trackId, track) {
  track.disable();
});

您可以对 videoTracks 执行相同的操作。要再次启用轨道，您将执行相同的操作，但使用 track.enable() .

让我知道这是否有帮助。
