我一直在尝试弄清楚如何使用 soundclouds API 中的 artwork_url为了将每个封面输出到 this custom player ，并且每个相应的拇指都位于播放列表中自己的轨道旁边？
我知道我需要使用 artwork_url 属性，但我不明白这是如何实现的，也不明白如何将其集成到 this particular custom player plugin 中。
任何特别的代码示例和/或帮助都将受到高度赞赏!
注意:如果能够通过 CSS 以外的其他方式控制图稿的“大小”，那就太好了。

我切换了Soundcloud Custom Player on Heroku因为在我能够启动并运行它之后，我发现与我上面引用的原始播放器相比，它的加载时间要快得多(尽管那个播放器仍然非常棒)...
我现在仍然面临着同样的任务，但是和以前一样 - 如何将专辑封面添加到脚本中并相应地输出？
下面粘贴的是Heroku玩家:
// # SoundCloud Custom Player
// Make sure to require [SoundManager2](http://www.schillmania.com/projects/soundmanager2/) before this file on your page.
// And set the defaults for it first:
soundManager.url = 'http://localhost:8888/wp-content/themes/earpeacerecords/swf';
soundManager.flashVersion = 9;
soundManager.useFlashBlock = false;
soundManager.useHighPerformance = true;
soundManager.wmode = 'transparent';
soundManager.useFastPolling = true;
// Wait for jQuery to load properly
$(function(){
// Wait for SoundManager2 to load properly
soundManager.onready(function() {
// ## SoundCloud
// Pass a consumer key, which can be created [here](http://soundcloud.com/you/apps), and your playlist url.
// If your playlist is private, make sure your url includes the secret token you were given.
var consumer_key = "915908f3466530d0f70ca198eac4288f",
url = "http://soundcloud.com/poe-epr/sets/eprtistmix1";
// Resolve the given url and get the full JSON-worth of data from SoundCloud regarding the playlist and the tracks within.
$.getJSON('http://api.soundcloud.com/resolve?url=' + url + '&format=json&consumer_key=' + consumer_key + '&callback=?', function(playlist){
// I like to fill out the player by passing some of the data from the first track.
// In this case, you'll just want to pass the first track's title.
$('.title').text(playlist.tracks[0].title);
// Loop through each of the tracks
$.each(playlist.tracks, function(index, track) {
// Create a list item for each track and associate the track *data* with it.
$('<li>' + track.title + '</li>').data('track', track).appendTo('.tracks');
// * Get appropriate stream url depending on whether the playlist is private or public.
// * If the track includes a *secret_token* add a '&' to the url, else add a '?'.
// * Finally, append the consumer key and you'll have a working stream url.
url = track.stream_url;
(url.indexOf("secret_token") == -1) ? url = url + '?' : url = url + '&';
url = url + 'consumer_key=' + consumer_key;
// ## SoundManager2
// **Create the sound using SoundManager2**
soundManager.createSound({
// Give the sound an id and the SoundCloud stream url we created above.
id: 'track_' + track.id,
url: url,
// On play & resume add a *playing* class to the main player div.
// This will be used in the stylesheet to hide/show the play/pause buttons depending on state.
onplay: function() {
$('.player').addClass('playing');
$('.title').text(track.title);
},
onresume: function() {
$('.player').addClass('playing');
},
// On pause, remove the *playing* class from the main player div.
onpause: function() {
$('.player').removeClass('playing');
},
// When a track finished, call the Next Track function. (Declared at the bottom of this file).
onfinish: function() {
nextTrack();
}
});
});
});
// ## GUI Actions
// Bind a click event to each list item we created above.
$('.tracks li').live('click', function(){
// Create a track variable, grab the data from it, and find out if it's already playing *(set to active)*
var $track = $(this),
data = $track.data('track'),
playing = $track.is('.active');
if (playing) {
// If it is playing: pause it.
soundManager.pause('track_' + data.id);
} else {
// If it's not playing: stop all other sounds that might be playing and play the clicked sound.
if ($track.siblings('li').hasClass('active')) { soundManager.stopAll(); }
soundManager.play('track_' + data.id);
}
// Finally, toggle the *active* state of the clicked li and remove *active* from and other tracks.
$track.toggleClass('active').siblings('li').removeClass('active');
});
// Bind a click event to the play / pause button.
$('.play, .pause').live('click', function(){
if ( $('li').hasClass('active') == true ) {
// If a track is active, play or pause it depending on current state.
soundManager.togglePause( 'track_' + $('li.active').data('track').id );
} else {
// If no tracks are active, just play the first one.
$('li:first').click();
}
});
// Bind a click event to the next button, calling the Next Track function.
$('.next').live('click', function(){
nextTrack();
});
// Bind a click event to the previous button, calling the Previous Track function.
$('.prev').live('click', function(){
prevTrack();
});
// ## Player Functions
// **Next Track**
var nextTrack = function(){
// Stop all sounds
soundManager.stopAll();
// Click the next list item after the current active one.
// If it does not exist *(there is no next track)*, click the first list item.
if ( $('li.active').next().click().length == 0 ) {
$('.tracks li:first').click();
}
}
// **Previous Track**
var prevTrack = function(){
// Stop all sounds
soundManager.stopAll();
// Click the previous list item after the current active one.
// If it does not exist *(there is no previous track)*, click the last list item.
if ( $('li.active').prev().click().length == 0 ) {
$('.tracks li:last').click();
}
}
});
});

所以我奇怪地能够解决一些问题......但是我不知道它在语义上是否正确......
$.getJSON('http://api.soundcloud.com/resolve?url=' + url + '&format=json&consumer_key=' + consumer_key + '&callback=?', function(playlist){
// I like to fill out the player by passing some of the data from the first track.
// In this case, you'll just want to pass the first track's title.
$('.title').text(playlist.tracks[0].title);
$('.album_art').attr('src', playlist.artwork_url);
// Loop through each of the tracks
$.each(playlist.tracks, function(index, track) {
// Create a list item for each track and associate the track *data* with it.
$('<li>' + '<img src="' + playlist.artwork_url + '">' + track.title + '</li>').data('track', track).appendTo('.tracks');
// * Get appropriate stream url depending on whether the playlist is private or public.
// * If the track includes a *secret_token* add a '&' to the url, else add a '?'.
// * Finally, append the consumer key and you'll have a working stream url.
url = track.stream_url;
(url.indexOf("secret_token") == -1) ? url = url + '?' : url = url + '&';
url = url + 'consumer_key=' + consumer_key;
// ## SoundManager2
// **Create the sound using SoundManager2**
soundManager.createSound({
// Give the sound an id and the SoundCloud stream url we created above.
id: 'track_' + track.id,
url: url,
// On play & resume add a *playing* class to the main player div.
// This will be used in the stylesheet to hide/show the play/pause buttons depending on state.
onplay: function() {
$('.player').addClass('playing');
$('.title').text(track.title);
},
onresume: function() {
$('.player').addClass('playing');
},
// On pause, remove the *playing* class from the main player div.
onpause: function() {
$('.player').removeClass('playing');
},
// When a track finished, call the Next Track function. (Declared at the bottom of this file).
onfinish: function() {

}

下面是与播放器配合使用的 HTML 和 CSS 标记，以便更好地说明...

<div class='title'></div>
<a class='prev'>Previous</a>
<a class='play'>Play</a>
<a class='pause'>Pause</a>
<a class='next'>Next</a>
</div>
CSS
/*

#sticky_header #sticky_content .player {
height: 570px;
overflow: hidden;
}
#sticky_header #sticky_content .tracks {

#sticky_header #sticky_content .tracks li img.album_art {

最佳答案
要获取图像，您可以使用以下代码:
//get element by id from your iframe
var widget = SC.Widget(document.getElementById('soundcloud_widget'));
widget.getCurrentSound(function(music){
artwork_url = music.artwork_url.replace('-large', '-t200x200');
$('#song1').css('background', 'url(\"'+artwork_url+'\") ');
});
通常你会得到一个末尾带有“-large”的链接，大小为 100x100。如果你想要其他尺寸，你必须像我一样用“.replace”改变结尾。您可以在这里找到可用尺寸的列表:
https://developers.soundcloud.com/docs/api/reference#tracks (我的尺寸 200x200 未列出，但可以使用。也许还有更多尺寸，例如每百像素。)
目前该代码仅适用于实际播放的歌曲。对我来说这不是一个解决方案，因为我需要播放列表中的所有图像。
