我有一个 Bootstrap 3.3.7 模式窗口,其中包含使用 HTML5 视频标签的视频,例如
<video controls autoplay>
<source src="video.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>
这样做的问题是,当我的网页加载时,视频开始播放(尽管由于模式关闭而无法“看到”视频,但音频也会播放)。
据我了解,autoplay
标签正在做这个。但是如何让视频在加载模式时自动播放呢?并在模态关闭时停止?
您可以使用shown.bs.modal
and hidden.bs.modal
当模式显示/隐藏时运行一些 javascript 代码的事件:
$('#myModal').on('shown.bs.modal', function () {
$('#video1')[0].play();
})
$('#myModal').on('hidden.bs.modal', function () {
$('#video1')[0].pause();
})
