javascript - 如何在 Bootstrap 模式关闭时停止 HTML 视频？

Question

我使用以下代码以模式显示嵌入视频，但是当我单击关闭按钮时，背景中的音频不会停止。尝试了很多 Stack Overflow 上提供的解决方案，但没有任何帮助。

HTML 代码:

  <div class="container" id="photocontainer">
<div class="row pt-5 ">
    <div class="col-sm-3" id="photocol">
       <img src="img/Cinematography/1Jacinta-Tyler.jpg" style="width:100%" onclick="openModal();currentSlide(1)" class="hover-shadow cursor"> 
    </div>
    <div class="col-sm-3" id="photocol">
       <img src="img/Cinematography/2Amanda-Mark.jpg" style="width:100%" onclick="openModal();currentSlide(2)" class="hover-shadow cursor"> 
    </div>

<div id="myModal" class="modal">
    <span class="close cursor" onclick="closeModal();">&times;</span>
    <div class="modal-content">
        <div class="mySlides" >
            <iframe src="player.vimeo.com/video/…; class="mt-5" width="740" height="316" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>
            <p>
                <a href="vimeo.com/255103005"; id="clr">
                    <b>Jacinta &amp; Tyler</b>
                </a>
            By <a href="vimeo.com/beautifullifestudios"; id="clr">Beautiful Life Studios</a>
            .</p> 
       </div>

脚本:

<script>
function openModal() {
  document.getElementById('myModal').style.display = "block";
}

function closeModal() {
  document.getElementById('myModal').style.display = "none";
}

var slideIndex = 1;
showSlides(slideIndex);

function plusSlides(n) {
  showSlides(slideIndex += n);
}

function currentSlide(n) {
  showSlides(slideIndex = n);
}

function showSlides(n) {
  var i;
  var slides = document.getElementsByClassName("mySlides");
  var dots = document.getElementsByClassName("demo");
  var captionText = document.getElementById("caption");
  if (n > slides.length) {slideIndex = 1}
  if (n < 1) {slideIndex = slides.length}
   for (i = 0; i < slides.length; i++) {
      slides[i].style.display = "none";
  }

  for (i = 0; i < dots.length; i++) {
      dots[i].className = dots[i].className.replace(" active", "");
  }
    slides[slideIndex-1].style.display = "block";
  dots[slideIndex-1].className += " active";
  captionText.innerHTML = dots[slideIndex-1].alt;
}

</script>

Answer 1

首先，澄清您正在使用 <video>标签或 <iframe>标签。如果您使用<video>标签，您可以分配 id到您的视频，例如 <video id="my_video">然后使用findElementById ，您可以使用play()和pause() closeModal() 中的方法功能。

否则，如果您使用 <iframe> ，首先为其提供 id像:

<iframe id="my_vide" class="embed-responsive-item" src="link_to_some_video"allowfullscreen></iframe>

您可以按如下方式进行:

function closeModal() {
    var video = document.getElementById("vid");
    document.getElementById('myModal').style.display = "none";
    document.getElementById('vid').src = '';
}

如果您有多个视频，您可以将源存储在数组中，并且只需传递每张幻灯片的索引并将其设置为 <iframe> 的源即可获取它们。 .

下面是代码示例:

// Video src
 var video_src = [
           "https://www.youtube.com/embed/sdUUx5FdySs?autoplay=1",
           "https://www.youtube.com/embed/YE7VzlLtp-4?autoplay=1"
];

var current_video = "";

var frame = document.getElementById('vid');

// slides
var slideIndex = 1;
showSlides(slideIndex);

function plusSlides(n) {
  showSlides(slideIndex += n);
}

function currentSlide(n) {
  showSlides(slideIndex = n);
  current_video = video_src[n-1];
  frame.src = current_video;

}
