css - 单击弹出窗口时如何暂停视频

Question

我对编程世界还很陌生，我正在开发一个网站，该网站将有一个按钮可以播放 YouTube 上的视频。我在网上找到了如何创建弹出窗口，但是一旦我点击退出视频，它仍然会播放视频并且您可以听到它在后台播放。

我尝试了不同的方法，但仍然无法弄清楚我的代码有什么问题。这是我的代码:

.lightbox {
	display: none;
	position: fixed;
	z-index: 999;
	width: 100%;
	height: 100%;
	text-align: center;
	top: 0;
	left: 0;
	background: rgba(0,0,0,0.8);
}
.lightbox:target {
	outline: none;
	display: block;
}


#videoModal {
  border-radius: 0;
  width: 870px;
  margin:auto;}
  #videoModal .modal-header {
    background: #000;
    border: 0;
    color: #fff;
    position: relative;
		  height:35px;
margin-bottom: 5px; }
    #videoModal .modal-header h3 {
      font-size: 18px;
      line-height: 22px;
	  font-family:Arial, Helvetica, sans-serif;
	  padding:5px;}
  #videoModal .modal-body {
    height: 489px;
    padding: 0;
    max-height: none;
    overflow: hidden; }
  #videoModal .modal-footer:empty {
    display: none !important; }
  #videoModal .close {
    background: none;
    color: #fff;
    font-size: 24px;
    margin: 0;
    opacity: 1;
    position: absolute;
    right: 0;
    text-shadow: none;
    top: 0;
    width: 38px; 
border-width: 0px !important;}

<a class="vid_link" data-fancybox-type="iframe" href="#img1"><img src="http://www.bbk.ac.uk/lib/images/general/PLAY.jpg" style="width:100%;height:auto;"></a>

</div></a>

希望您能接受 JQuery。您可以在下面添加 JS 代码。确保从您的视频 iFrame 中删除 src，因为它将在文档准备就绪时以编程方式设置。给播放按钮分配一个id；我假设 id 是 playBtn。由于页面在刷新时跟踪最近的播放/暂停状态，如果按钮处于播放模式，我们只需要在加载时设置 src。单击播放按钮后，我们只会在空白和您的视频链接之间切换 src。答案中有一个更新的片段，但我知道由于 YouTube API，它在 Stackoverflow 中不起作用。因此，我给出了这个简短的描述，让您知道我做了什么。

$(document).ready(function(){
    var isVisible = $('#img1:visible').length;
    var src = 'https://www.youtube.com/embed/84V4AQIZMUg?rel=0&autoplay=1';

    if(isVisible){
        $('iframe').attr('src', src);
    }


$('#playBtn, #img1').click(function(){      
        $('iframe').attr('src', $('iframe').attr('src')? "": src);
    });

});

$(document).ready(function(){
    var isVisible = $('#img1:visible').length;
	var src = 'https://www.youtube.com/embed/84V4AQIZMUg?rel=0&autoplay=1';

	if(isVisible){
		$('iframe').attr('src', src);
	}


	$('#playBtn, #img1').click(function(){      
	        $('iframe').attr('src', $('iframe').attr('src')? "": src);
	    });
	
	});

.lightbox {
	display: none;
	position: fixed;
	z-index: 999;
	width: 100%;
	height: 100%;
	text-align: center;
	top: 0;
	left: 0;
	background: rgba(0,0,0,0.8);
}
.lightbox:target {
	outline: none;
	display: block;
}


#videoModal {
  border-radius: 0;
  width: 870px;
  margin:auto;}
  #videoModal .modal-header {
    background: #000;
    border: 0;
    color: #fff;
    position: relative;
		  height:35px;
margin-bottom: 5px; }
    #videoModal .modal-header h3 {
      font-size: 18px;
      line-height: 22px;
	  font-family:Arial, Helvetica, sans-serif;
	  padding:5px;}
  #videoModal .modal-body {
    height: 489px;
    padding: 0;
    max-height: none;
    overflow: hidden; }
  #videoModal .modal-footer:empty {
    display: none !important; }
  #videoModal .close {
    background: none;

    position: absolute;
