模式打开时在 Bootstrap 模式窗口中自动播放视频答案

【问题标题】：Autoplay video in Bootstrap modal window on modal opening模式打开时在 Bootstrap 模式窗口中自动播放视频
【发布时间】：2016-11-29 14:40:15
【问题描述】：

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（即使由于模式关闭而无法“看到”视频，但音频也会播放）。

我了解autoplay 标签正在执行此操作。但是，当模态加载时，如何让视频自动播放？并在模态关闭时停止？

【解决方案1】：

当模态显示/隐藏时，您可以使用shown.bs.modal 和hidden.bs.modal 事件来运行一些javascript代码：

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

【解决方案2】：

您应该使用 javascript 函数来启动视频并在加载模式时调用它：（并删除 autoplay 属性）这是一个例子：

var vid = document.getElementById("myVideo"); 
function playVid() { vid.play(); }
