Question

我想列出一个包含播放列表中曲目的普通列表。我有问题列出该列表中的曲目，我只是得到了字段（曲目，艺术家，时间，星级，nr和更多）的头部，这是灰色的。这是唯一出现的，没有曲目出现，看起来很奇怪。

这是我正在使用的功能：

function setPlaylistWithTopic(playlisturi, row) {
    // Play multiple tracks
    console.log(playlisturi);

    models.Playlist.fromURI(playlisturi).load(['name','owner', 'tracks', 'description']).done(function(playlist) {
        console.log("came in");
        console.log(playlist);
        var multiple_tracks_player = document.getElementById(row);
        multiple_tracks_player.className = multiple_tracks_player.className + " sp-list-style-rounded albumlist";

        console.log(playlist);

        var list = List.forPlaylist(playlist);

        var image = Image.forPlaylist(playlist, {width: 65, height: 65});

        var playlistname = playlist.name;
        var playlistowner = playlist.owner;
        if(playlistname.length > 75) {
            playlistname=playlistname.substr(0,75) + "..";
        }
        $("#"+row).append("<div class='col-md-12 col-sm-12 col-xs-12 row'><div class='pull-left' id='albumcover'></div><div class='albumhead' id='"+playlisturi+"'><h3><a href='"+playlisturi+"'>"+playlistname+"</a></h3><span class='label col-md-12 row'>"+playlistowner+"</span></div></div>").append(list.node);
        $("#"+row + " #albumcover").append(image.node);
        $("#"+row + " .albumhead").append("<button class='sp-button sp-add-to-collection-button sp-button-accentuated-positive sp-button-accentuated' style='min-width: 156.15625px;'><span class='sp-button-text'><div class='sp-button-icon sp-icon-add'></div>Subscribe</span><span class='sp-button-background'></span></button>");
        $("#"+row + " #"+playlisturi+" .sp-add-to-collection-button").die("click");
        $("#"+row + " #"+playlisturi+" .sp-add-to-collection-button").live('click',function(e){
                //Subscribe on playlist
                e.preventDefault();
        });

        list.init();
    });
}

我正在使用jQuery和Spotify的API版本1.30.0，我认为它应该是1.0.0，但我测试改为1.30.0，同时查看API文档时它不起作用，并且查看了1.3 * .0版本。

我做错了什么？

playlisturi 变量包含冒号，需要使用 \\：

进行转义

var escapedPlaylistUri = playlisturi.replace(":","\\:");
$("#" + row + " #" + escapedPlaylistUri + " .sp-add-to-collection-button").die("click");
$("#" + row + " #" + escapedPlaylistUri + " .sp-add-to-collectionbutton").live('click', function(e) { ...

“使用任何元字符（例如！“＃$％＆amp;'（）* +，。/：;＆lt; =＆gt;？@ [] ^`{|}〜）作为名称的字面部分，必须用两个反斜杠逃脱：\。“ - http://api.jquery.com/category/selectors/

Spotify app - List不显示播放列表的曲目，只显示thead
