为你的网站引入APlayer和Meting，播放网易云、QQ等各平台音乐

之前本站的音乐播放器使用的是APlayer插件，今天无意中发现一个只需加载JS，即可调用 APlayer 和 Meting，不依赖插件和服务器计算存储，任意站点都可使用的来播放 网易云，QQ 音乐，酷狗，虾米，百度 以及 自定义的 单曲和歌单的方法，在此记录并分享给大家。

引入 JS

将代码加入到主题对应的 header.php 中的 </head> 标签前即可

<script>
    // APlayer API
    document.addEventListener('DOMContentLoaded', initAplayer);
    window.aplayers = window.aplayers || [];

如果你开启了 PJAX，可能需要单独加入回调函数。将 initAplayer(); 添加进回调函数即可。
