我正在使用photoswipe来查看灯箱和iframe视频中的图片。但是在iframe中无效。我可以编码来查看photoswipe lighbox中的视频。

我试试这个。

我不知道该怎么做。我不知道它的可能与否。并提前感谢。

在我的jAlbum PhotoSwipe皮肤中,请参阅http://jalbum.net/nl/skins/skin/PhotoSwipe, 我为视频使用了一个非常简单的解决方案:

// build items array
var items = [
  {
    html: '<video controls autoplay><source src="slides/IMG_4979.mp4" type="video/mp4"></video>'
  },

要查看它的实际效果,请点击PhotoSwipe皮肤样本相册的第3个缩略图:http://andrewolff.jalbum.net/Reestdal_PS/
