Spotify API - 创建临时播放列表

Question

我正在尝试使用以下代码通过Spotify API创建临时播放列表：

var playlist = models.Playlist.createTemporary("My temporary playlist");
models.Playlist.createTemporary("My temporary playlist").load('tracks').done(function(playlist) {
    playlist.tracks.add(models.Track.fromURI("spotify:track:4VqPOruhp5EdPBeR92t6lQ"));
    playlist.tracks.add(models.Track.fromURI("spotify:track:5HF5PRNJ8KGtbzNPPc93tG"));
});

var list = List.forPlaylist(playlist);
document.getElementById('playlistContainer').appendChild(list.node);
list.init();

但我收到以下错误：

core.js:4 - Uncaught TypeError: Object #<Promise> has no method 'load'

知道我做错了什么吗？感谢。

我找到了解决方案，但仍然不确定为什么会这样，我以前的代码没有，但是你去了：

models.Playlist.createTemporary(playlist_name).done(function(playlist) {
  playlist.load('tracks').done(function(loadedPlaylist) {
    loadedPlaylist.tracks.add(models.Track.fromURI("spotify:track:4VqPOruhp5EdPBeR92t6lQ"));
    loadedPlaylist.tracks.add(models.Track.fromURI("spotify:track:5HF5PRNJ8KGtbzNPPc93tG"));
  });

  var list = List.forPlaylist(playlist);
  document.getElementById('playlistContainer').appendChild(list.node);
  list.init();
});
