MDN’s new design is in Beta! A sneak peek:


The MediaStreamTrack.onunmute event handler is a property called when the unmute event is received. Such an event is sent when the track is again able to send data.


track.onunmute = function;


  • function is the name of a user-defined function, without the () suffix or any parameters, or an anonymous function declaration, such as function(event) {...}. An event handler always has one single parameter, containing the event, here of type Event.


dc.onunmute = function(ev) { alert("unmute event detected!"); };
