jquery - Cycle 2 HTML 5 Video Plugin 播放/暂停仅适用于奇数而不是偶数

Question

所以我正在为 Cycle2 幻灯片插件制作一个 HTML5 视频插件。

什么是工作:

第一张幻灯片视频自动播放，如果视频播放完毕，它会自动转到下一张幻灯片。 如果下一张幻灯片是视频，它会自动播放那个。 如果您在幻灯片之间切换，则会暂停上一张视频幻灯片并播放新幻灯片。 视频幻灯片上禁用了超时，因此可以播放整个视频

什么不起作用:

点击 .cycle-slideshow 时播放/暂停视频元素。这是部分工作!发生的情况是 p/p 在您第一次看到幻灯片时完美运行，但在您第二次看到该幻灯片时却无法正常工作。第 3 次。第 4 次它没有。

因此在 ODD 上有效，在 EVEN 上无效!

(function($) {
$(document).ready(function() {
// We add a class for targetting
$('.lsss-video').parent().addClass('cycle-slide-html5video');

// We assign a id to this class
$('.cycle-slide-html5video').attr('id', 'lsss-video');

// Autoplay the video in the first slide on page load and after each transition

  if ($(currentSlideEl).is('#lsss-video')) {
    // Video element is present so we continue with playing the video
