问题描述
是否有一种方法可以以编程方式控制我想要的选项卡上的音频电平，而不管Web应用程序是如何设计的(无论是HTML5音频元素还是Flash等)?
Is there a way to programmatic-ally control audio level on tabs i want to regardless of how web app was designed (be it HTML5 Audio element or Flash, etc.)?
为了明确起见，我无意研究某些"id""elements"之类的网页，但不喜欢Chrome.ThisAudioOutputLevels ...之类的东西?
Just to make it clear i don't intend to research web page for some "id" "elements" or whatsoever, but something like Chrome.ThisAudioOutputLevels...?
推荐答案
承认音频来自<audio> HTML元素，您可以尝试从DOM中获取所有音频元素并降低其音量.我在Google环聊会议上遇到了这个问题，在这里我无法降低音频，因为它无法控制任何声音.
Admitting that the audio comes from a <audio> HTML element, you can try to get all audio elements from the DOM and lower their volumes. I was suffering from this with google hangouts meetings where I couldn't lower the audio because it had no control whatsoever.
我选择了所有<audio>元素并降低了它们的音量.请按照下列步骤操作:
I selected all <audio> elements and lowered their volumes. Follow these steps:
- 在给定的选项卡上打开控制台. (按F12键.)
- 选择所有音频元素.
- 降低每个音频音量.
let audios = [...document.getElementsByTagName('audio')];
audios.forEach(audio => audio.volume = 0.5) // lower volume 50%.
音量范围= {0..1}，其中0 =无音量.
Volume range = {0..1} where 0 = no volume.
