我正在设计一个乐队网站，Reverbnation在页脚中有一个很酷的音乐播放器，可以让音乐在换页时继续播放。
我查看了代码，但我看不到任何使用框架的证据。这是我知道实现这样的事情的唯一方式。但HTML5不再支持这种方式，也是SEO的废话。
播放器的源代码中有一些JavaScript，但我不知道有足够的JavaScript来判断它是否有责任。这样的事情对我正在建设的网站非常有用。
我会尝试谷歌搜索，但我不知道我会用什么关键词来寻找关于这个主题的方法。
由于代码很长，所以如果有人愿意看一下，我会把它剪切并粘贴在这里。
这是我的代码：

您所指的页面是单页网站。它们不会更改页面，而是使用javascript和ajax请求更改单页的外观。这就是玩家继续玩的原因。
