I have a simple implementation in JavaScript that plays songs from a playlist continuously until it ends. I have not been able to find which is the proper way to implement it in AngularJS. This exercise should address the desired features:

• Encapsulate player as a service
• Do I need to use directives to access the control?
• Catch the "end" event to start the new song

Here is an excerpt of the HTML file.

...
<div class="span4">
  <button class="btn btn-large btn-primary" type="button" ng-click="startPlaying();">Start Playing</button>
</div>
...
<div class="span6">
  <h4 id="NowPlayingID">Now Playing: </h4>
  <audio id="AudioPlayerID" controls="controls">
  </audio>
</div>
...

<!-- OLD JavaScript code -->
<script type="text/javascript">
  function playNextSong(player) {
    if (playlist.currentSongIX >= playlist.songs.length) 
        return;
    $('#NowPlayingID').text('Now Playing: ' + playlist.songs[playlist.currentSongIX].name);
    player.src = playlist.songs[playlist.currentSongIX].path;
    player.play();
    playlist.currentSongIX++;
  }
  function startPlaying() {
    var player = document.getElementById("AudioPlayerID");
    player.addEventListener('ended', function() {
        playNextSong(player);
        }, false);
    playNextSong(player);
  };
</script>

---

The following code is work in progress and inplete:

app.controller('PlayCtrl', function($scope, $routeParams, Playlist, $log, $document) {
  $scope.playlist = Playlist.get({playlistID:$routeParams.playlistID});
  var player = ????? ("AudioPlayerID");
  $scope.startPlaying = function () {
      angular.forEach($scope.playlist.songs, function(song) {
  $log.log("Playing: " + song.name);
  player.src = song.path;
  player.play();
      });
  };
});

...

My questions are:

1. Which is the proper way to access the audio player?
2. Do I need to use directives?
3. How do I catch the 'end' event?

• javascript
• angularjs
• angularjs-directive
• dom-events

I've build a html player backended by flash to play music, so build my own event flow to to the operations, but I think that the best way is to write an directive to do that. In this case you can re-use the directive if you need to and it works very well.

If you have the player object into your directive, you can catch all events normally.

Take a look on this website: Angular Tunes and check out the sources to see what he does. It's the same as you trying to do.

I hope it helps.
