我只想让您点击的播放器同时播放而不是全部播放，如果您点击页面上的所有播放器打开播放列表，则与下拉播放列表相同。希望我有意义并提供足够的信息..如果有人可以帮助请

Answer 1

我希望你可以尝试这样的东西遍历div树。

console.log($(elem).parent().closest('div.example').attr('id'));

elem是$（＆＃39; .playlist li：first-child＆＃39;）在你的情况下

initAudio($('.playlist li:first-child'));

我怎么能在一个页面上有两个这样的音频播放器，而不点击一个，另一个播放或显示隐藏播放列表
