的SoundCloud播放器上移动/ iOS版

Question

我在这个网站嵌入多个玩家的SoundCloud锁定了：http://www.familyartists.com

击中的玩家的SoundCloud的播放按钮，使播放按钮褪色到一个暂停按钮，但不实际玩和该网站冻结了一段时间。

页面是否占用了过多的资源？

在使用Safari运行8.1的iPhone 5上，我可以一个接一个地播放音轨，但UI会定期冻结，并且按下播放按钮时不会始终开始播放。检查Safari日志，我看到一些IndexSizeError：DOM异常。实际的设备日志显示有多少内存警告：

好像你正在做的有点过分的设备来处理。
