Question

当我点击按钮时，我的声音正在播放，但是当我重新点击它时它不会暂停或停止。显示else块的警报正在工作，所以我认为它是第二个sc.stream。见下面的代码：

var i = $('.song').attr('id');
var is_playing = false;

$('.song').click(function(){
    if(is_playing == false){
        SC.stream('/tracks/'+i).then(function(player){
            player.play();
        });
        is_playing = true;
    } else {
        SC.stream('/tracks/'+i).then(function(player){
            player.pause();
        });
        alert('This alert works when is_playing is true');
        is_playing = false;
    }
});

您当前正在创建两个单独的流（以及两个单独的player个对象）。您需要先创建播放器并使其在回调之外可用，例如将其存储在全局变量中：

var i = $('.song').attr('id');
var is_playing = false;
var player;
SC.stream('/tracks/'+i).then(function(stream){
            player = stream;
        });

$('.song').click(function(){
    if(is_playing == false){
        player.play();
        is_playing = true;
    } else {
        player.pause();
        alert('This alert works when is_playing is true');
        is_playing = false;
    }
});
