在Fancybox中自动播放HTML5视频

Question

我正在使用Fancybox显示单个HTML5视频以及HTML5视频库的项目。

对于单个视频，我打算在Fancybox中打开视频后立即自动播放视频，然后在视频播放完毕后关闭Fancybox。

对于图库中的视频，我想在Fancybox中打开视频时自动播放视频，当视频播放完时前进到下一个图库项目，并暂停当前视频/自动播放下一个/上一个视频if用户浏览画廊。

我已经包括这里codepen：http://codepen.io/ericjacksonwood/pen/kXKkaq/，其中包括一些我试图用的fancybox的“负荷”功能的工作：

// Attempt 01  
$(".fancybox-video").find('video').play(); 

// Attempt 02 
$(".fancybox-video").find('video').attr('autoplay','autoplay'); 

// Attempt 03 
var vid = document.getElementsByClassName("fancybox-video"); 
function playVid() { 
    vid.play(); 
} 

任何帮助，将不胜感激！谢谢。

的codepen已经更新，工作正常。

您可以使用html5的媒体methods和events。

我使用play方法在幻灯片放映动画完成后启动视频，当视频结束时使用ended回调调用fancybox.next()函数。

这里是一个工作版本，您可以检查：

$(document).ready(function() { 
 
    $(".fancybox").fancybox({ 
 
    afterShow: function() { 
 
     // After the show-slide-animation has ended - play the vide in the current slide 
 
     this.content.find('video').trigger('play') 
 
     
 
     // Attach the ended callback to trigger the fancybox.next() once the video has ended. 
 
     this.content.find('video').on('ended', function() { 
 
     $.fancybox.next(); 
 
     }); 
 
    } 
 
    }); 
 
});

.fancybox-video { 
 
    display: none; 
 
} 
 

 
.fancybox-nav { 
 
    top: 50%; 
 
    -webkit-transform: translateY(-50%); 
 
      transform: translateY(-50%); 
 
    height: 40%; 
 
}
