我希望能够禁用 Spotify 中的“下一个”和“上一个”按钮。我知道这是可能的,因为 soundrop 应用程序已经做到了。

我已经搜索了一下,据我了解,我应该播放上下文为空的曲目或仅包含 1 首曲目的上下文。我一直在测试我能想到的所有可能的解决方案,但它们似乎都不起作用。它们中的大多数实际上会导致在上下文为 null 的情况下播放曲目,但始终启用 Next/Previous 按钮。

如果我按下下一个按钮,播放器最终不会播放任何曲目,并且两个按钮都被禁用......

下面是我的测试应用程序的代码。

var sp = getSpotifyApi(1);
var models = sp.require('sp://import/scripts/api/models');
var views = sp.require('sp://import/scripts/api/views');

models.player.observe(models.EVENT.CHANGE, function (o) {
    console.log(['Player Change', o, models.player.context]);
})

$('#play1').click(function () {
    models.Track.fromURI("spotify:track:5A1fNC7Fdb0yyh3UA6T1ef", function (track) {
        console.log(["play1", track.name]);
        models.player.play(track, null);
    });
});

$('#play2').click(function () {
    models.Track.fromURI("spotify:track:5A1fNC7Fdb0yyh3UA6T1ef", function (track) {
        console.log(["play2", track.name]);
        var p = new views.Player();
        p.play(track, null);
    });
});

$('#play3').click(function () {
    models.Track.fromURI("spotify:track:5A1fNC7Fdb0yyh3UA6T1ef", function (track) {
        console.log(["play3", track.name]);
        var pl = new models.Playlist();
        pl.add(track);
        models.player.play(track, pl);
    });
});

$('#play4').click(function () {
    console.log(["play4"]);
    models.player.play("spotify:track:5A1fNC7Fdb0yyh3UA6T1ef", null);
});

$('#play5').click(function () {
    models.Track.fromURI("spotify:track:5A1fNC7Fdb0yyh3UA6T1ef", function (track) {
        models.player.playTrack(track);
    });
});

$('#play6').click(function () {
    models.Track.fromURI("spotify:track:5A1fNC7Fdb0yyh3UA6T1ef", function (track) {
        console.log(["play6", track.name]);
        var pl = new models.Playlist();
        pl.add(track);
        models.player.playTrackWithContext(track, pl, 0);
    });
});

$('#play7').click(function () {
    var l = new models.Link("spotify:track:5A1fNC7Fdb0yyh3UA6T1ef");
    sp.trackPlayer.setContextCanSkipNext(l, false);
    console.log(["play7", models.player, sp.trackPlayer],l);
    models.player.play(l, null);
});

#play1 的结果:

["play1", "Jag är här nu"]
["Player Change", Object, null]

#play2 的结果:

["play2", "Jag är här nu"]
["Player Change", Object, null]

#play3 的结果:

["play3", "Jag är här nu"]
["Player Change", Object, "spotify:internal:temp_playlist:spotify:app:myapplication@687556942764"]

#play4 的结果:

["play4"]
["Player Change", Object, null]

#play5 的结果:

["play5", "Jag är här nu"]
["Player Change", Object, null]

#play6 的结果:

["play6", "Jag är här nu"]
["Player Change", Object, "spotify:internal:temp_playlist:spotify:app:myapplication@217702072872"]

#play7 的结果:

sp.trackPlayer.setContextCanSkipNext(l, false);

我现在做了一些工作,发现了如何做到这一点。

models.Track.fromURI("spotify:track:5A1fNC7Fdb0yyh3UA6T1ef", function (track) {
    var pl = new models.Playlist();
    sp.trackPlayer.setContextCanSkipPrev(pl.uri, false);
    sp.trackPlayer.setContextCanSkipNext(pl.uri, false);
    pl.add(track);
    models.player.play(track, pl);
});

希望这可以帮助其他试图解决此问题并陷入谈论在空上下文中播放曲目的讨论...
