soundmanager2 - 第二期播放

Question

我的问题是一旦音轨停止播放并且您第二次按下播放按钮，歌曲就不会播放。我的意思是我听不到任何声音，但第一次工作正常。

 soundManager.url = '{{ asset('bundles/bm/swf/')}}';
    soundManager.onload = (function() {
        var preview = soundManager.createSound({
            id: 'previewer',
            url: '{{ path('play_track', { 'id' : track.id}) }}',
            type: 'audio/mp3'
        });
        preview.options.whileplaying = function() {
            var current  = new Date (this.position),
                minutes  = current.getMinutes(),
                seconds  = current.getSeconds();

            var current = minutes + ':' + seconds;

            $('.editable').html(current);
        }

        $('.bigPlay').click(function(e){
            if($(this).hasClass('playbtn')) {
                e.stopPropagation();
                $(this).removeClass('playbtn').addClass('pausebtn');
                preview.play({
                    onfinish: function() {
                        preview.stop();
                        $('.bigPlay').removeClass('pausebtn').addClass('playbtn');
                    }
                });


                return false;
            }

            if($(this).hasClass('pausebtn')) {
                e.stopPropagation();
                $('.bigPlay').removeClass('pausebtn').addClass('playbtn');
                preview.stop();

                return false;
            }
        });
    });

任何帮助都会很棒。

所以我不是 SoundManager2 方面的专家，但我能够修复一个非常像这样的错误。对我来说，这是我的服务器。返回音频数据时需要设置 HTTP header 。

技术说明部分列出了您需要提供的一些基本内容: http://www.schillmania.com/projects/soundmanager2/doc/technotes/

正确设置这些 header 将播放音频。我需要再添加几个标题才能让 SoundManger2 让我播放两次声音。这是我的浏览器获取响应和 mpeg 文件的 header 。我可能需要也可能不需要“Accept-Ranges” header :

Accept-Ranges:bytes
Connection:close
Content-Length:30592
Content-Type:audio/mpeg
Server:Jetty(6.1.x)
