在模态打开的Bootstrap模态窗口中自动播放视频

Question

我有一个Bootstrap 3.3.7模式窗口,其中包含一个使用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(即使它不能被"看到",因为模态关闭,音频也会播放).

我知道autoplay标签正在这样做.但是如何在加载模态时让视频自动播放？当模态关闭时停止？

当显示/隐藏模态时,您可以使用shown.bs.modal和hidden.bs.modal事件运行一些javascript代码:

$('#myModal').on('shown.bs.modal', function () {
  $('#video1')[0].play();
})
$('#myModal').on('hidden.bs.modal', function () {
  $('#video1')[0].pause();
})
