Question

我希望在包含YouTube视频的幻灯片中放一张幻灯片。它应该：

暂停鼠标悬停
播放YouTube视频时暂停
包含分页

我使用JQuery Cycle Plugin进行幻灯片放映。 http://jquery.malsup.com/cycle/

并使用了YouTube的iframe API https://developers.google.com/youtube/iframe_api_reference

幻灯片暂停并恢复正常播放/暂停视频;但是，如果您将鼠标移出视频幻灯片，它将会恢复。

有没有办法使用JQuery Cycle Plugin阻止这种情况？

感谢。

Answer 1

不是确切问题的解决方案 - 而是一个简单的替代方案。

由于您使用循环 - 升级到cycle2 - http://jquery.malsup.com/cycle2/ - youtube视频已经有一个cycle2扩展名（检查下载部分）。

您可以使用90％的代码，因为语法大致相同 - 除了一些新选项（很少有重命名）。
