这是我对使用JavaScript SDK的自定义Soundcloud播放器的解释。我希望在最后一首曲目完成后重置播放列表,这部分是有效的 - 第一首曲目已正确设置,但我的下一首/上一级按钮的计数器变量不会更新。
或许有更好的方法来循环播放列表而不是使用计数器变量?
var autoplay = false;
$(document).ready(function() {
SC.get( '/resolve', {url: 'https://soundcloud.com/rockcurrent/sets/rc-playlist-new-rock-releases'}, function(pl) {
var i = 0;
var track_url = pl.tracks[i].uri;
var stream_sound = function(i) {
track_url = pl.tracks[i].uri;
SC.stream(track_url, function(sound) {
var new_play = function() {
sound.play({
onplay: function() {
title(i);
},
whileplaying: function() {
loader(this.position, this.duration);
},
onfinish: function() {
if (i < pl.tracks.length -1) {
i++;
autoplay = true;
}
else {
i = 0;
}
stream_sound(i);
}
});
}
new_play();
sound.pause();
if (autoplay) {
sound.resume();
is_playing = true;
}
autoplay = false;
$('#play').on('click', function() {
togglePause();
});
});
}
stream_sound(i);
$('#next').on('click', function() {
soundManager.stopAll();
if (i < pl.tracks.length -1) {
i++;
}
autoplay = true;
stream_sound(i);
});
$('#prev').on('click', function() {
soundManager.stopAll();
if (i > 0) {
i--;
}
autoplay = true;
stream_sound(i);
});
});
});
