JS啓用和禁用麥克風

Question

我試圖啓用和禁用我的麥克風，但我真的無法得到它的工作，我是新來的JavaScript。

使用的WebRTC

navigator.getUserMedia({"audio":USE_AUDIO}, 
       function(stream) { /* user accepted access to a/v */ 
        console.log("Access granted to audio/video"); 
        local_media_stream = stream; 
        var local_media = $("<audio>"); 
        local_media.attr("autoplay", "autoplay"); 
        local_media.attr("muted", "true"); /* always mute ourselves by default */ 
        local_media.attr("controls", ""); 
        $('body').append(local_media); 
        attachMediaStream(local_media[0], stream); 

        if (callback) callback(); 

        $('.testHold').mousedown(function() { 
         $('.tracker').html("holding holding holding"); 
          local_media.attr("muted", "false"); 

        }).bind('mouseup mouseleave', function() { 
         $('.tracker').text('Left the button'); 
         local_media.attr("muted", "true"); 

        }); 

       } 

Answer 1

$('.testHold').mousedown(function() { 
         $('.tracker').html("holding holding holding"); 
         stream.getAudioTracks()[0].enabled = true; 

        }).bind('mouseup mouseleave', function() { 
         $('.tracker').text('Left the button'); 
         stream.getAudioTracks()[0].enabled = false; 

        });
