How can I get the html5 audio's duration time

Question

I have a html5 tag in page, but how can I know its duration time?

Answer 1

I used "canplaythrough" event to get the track duration. I have a case where I have two players, and I want to stop the second player 2 seconds before the first one is complete.

$('#' + _currentPlayerID).on("canplaythrough", function (e) {   
    var seconds = e.currentTarget.duration;    
    var trackmills = seconds * 1000;
    var subTimeout = trackmills - 2000; //2 seconds before end

    //console.log('seconds ' + seconds);
    //console.log('trackmills ' + trackmills);
    //console.log('subTimeout ' + subTimeout);

    //Stop playing before the end of thet track
    //clear this event in the Pause Event
    _player2TimeoutEvent = setTimeout(function () { pausePlayer2(); }, subTimeout);

});
