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

while ($row = $result->fetch_assoc()) {
    echo $row['RegNumber'];
    echo $row['Colour'];
}

问题在于，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）。

我了解<video controls autoplay> <source src="video.mp4" type="video/mp4"> Your browser does not support the video tag. </video>标记正在执行此操作。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？

Answer 1

您可以使用shown.bs.modal和hidden.bs.modal事件在显示/隐藏模态时运行一些javascript代码：

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

      <div class="modal-body">
        <video controls id="video1" style="width: 100%; height: auto; margin:0 auto; frameborder:0;">
          <source src="https://archive.org/download/WebmVp8Vorbis/webmvp8_512kb.mp4" type="video/mp4">
          Your browser doesn't support HTML5 video tag.
        </video>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>

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

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

$(document).ready(function(){

autoPlayYouTubeModal();

//FUNCTION TO GET AND AUTO PLAY YOUTUBE VIDEO FROM DATATAG
function autoPlayYouTubeModal() {
  var trigger = $("body").find('[data-toggle="modal"]');
  trigger.click(function () {
      var theModal = $(this).data("target"),
          videoSRC = $(this).attr("data-theVideo"),
          videoSRCauto = videoSRC + "?autoplay=1";
      $(theModal + ' iframe').attr('src', videoSRCauto);
      $(theModal + ' button.close').click(function () {
          $(theModal + ' iframe').attr('src', videoSRC);
      });
      $('.modal').click(function () {
          $(theModal + ' iframe').attr('src', videoSRC);
      });
    //video play on click
    $('.video-player-main iframe')[0].contentWindow.postMessage('{func":"playVideo":""}', '*');
