javascript - How do I append a song to a currently playing playlist in a Spotify app?

Question

I have a simple spotify (JS) app and I want to either:

• Create a new playlist with the first track and play it, or

• Append the song to the currently playing playlist

   var playlist = new models.Playlist();
  
   ...
  
   var search = new models.Search(query);
  
   search.observe(models.EVENT.CHANGE, function() {
      if (search.tracks.length) {
        var track = search.tracks[0];
        playlist.add(track);
        if (!models.player.playing) 
           models.player.play(track, playlist);
      }     
    });
  
    search.appendNext(); 
  

Shouldn't this simply append the new track to the existing playlist? (playlist is scoped higher up, and it is definitely not re-created each time).

Currently nothing happens when a track is playing.

它确实有效，但播放列表视图需要很长时间才能呈现为更新。（尽管它会立即附加曲目 - 点击下一步可以看到）。但是，正如评论中所提到的，它在使用名称创建时不会播放播放列表，只会播放临时的并因此具有 URI 的播放列表。
