Question

我对编码世界非常陌生，我正在开发一个网站，它将有一个按钮，可以播放来自youtube的视频。我在网上找到了如何创建弹出窗口，但是一旦我点击视频，它仍会播放视频，你可以听到它在后台播放。

我尝试了不同的东西，但我仍然无法弄清楚代码的问题是什么。这是我的代码：

＆＃13;

.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;}

＆＃13;

<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> 


<!-- lightbox container hidden with CSS -->
<a href="#_" class="lightbox" id="img1">
<div id="videoModal" class="modal hide fade in" tabindex="-1" role="dialog" aria-labelledby="videoModalLabel" aria-hidden="false" style="display: block;">
  <div class="modal-header">
    <button type="button" class="close full-height" data-dismiss="modal" aria-hidden="true">X</button>
    <h3>Mumford and Sons: Broad-Shouldered Beasts</h3>
  </div>
  <div class="modal-body"><iframe width="870px" height="489px" src="https://www.youtube.com/embed/84V4AQIZMUg?rel=0&autoplay=1" frameborder="0" allowfullscreen=""></iframe></div>
  <div class="modal-footer"></div>
</div></a>

希望你对JQuery没问题。您可以在下面添加JS代码。确保从视频iFrame中删除src，因为它将在文档准备好后以编程方式设置。为播放按钮分配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，因此我们只需要在加载时设置src，如果按钮处于播放模式。单击播放按钮后，我们只在空白和视频链接之间切换src。答案中有一个更新的代码段，但我知道由于YouTube API，它在Stackoverflow中无效。因此，我给出了这个小小的描述，让你知道我做了什么。

$(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);
    });

});

＆＃13;

$(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);
	    });
	
	});
