静音事件javascript上的音频HTML5？ 在MVC中

Question

I need to find some event that fires,when i press mute button.On volumechange works only, when i change volume.

  <audio id="volumeController" onvolumechange="changeVolume()"controls>
            <source src="~/Sounds/beep.mp3" type="audio/mpeg"/>
        </audio>

also i tried to use onclick and onchange events but instead of current volume,it sends always 1 instead of 0.

In HTML5 there isn't any mute event , when you click on mute and media gets muted it still counted as volumechange event .But there is another way that you can discern whether it's a mute or regular volumechage ; you can use muted property it gets set to true when you mute false otherwise

var audio = document.getElementById('audio');

audio.addEventListener('volumechange',function(e){
  if(this.muted)
        console.log('Audio muted');
}, false);
