在我的代码中，当用户单击按钮时，youtube 视频会出现在弹出窗口中。
我希望视频仅在有人单击按钮并出现弹出窗口时加载，并在有人关闭框时停止播放。
目前，我的代码只是隐藏显示，仅此而已。
HTML：
<button id="watchbutton">Watch Trailer ►</button>
<div id="close">
<div id="trailerdivbox" >
<div class="videoWrapper">
<iframe class="trailervideo" width="560" height="315"
src="https://www.youtube.com/embed/TDwJDRbSYbw" frameborder="0"
allowfullscreen></iframe>
</div>
</div>
</div>
CSS：
/* Watch Trailer Button CSS */
#watchbutton {
background-color:#f2f2f2;
color:red;
font-weight:600;
border: none; /* This one removes the border of button */
padding: 10px 12px;
}
#watchbutton:hover {
background-color:#e2e2e2;
cursor:pointer;
}
#trailerdivbox {
display:none;
width: 100%;
height:100%;
position:fixed;
overflow: auto; /* Enable Scrolling */
background-color: rgb(0,0,0); /* Fallback color */
background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
}
.videoWrapper {
position: relative;
padding-bottom: 56.25%; /* 16:9 */
padding-top: 25px;
height: 0;
}
.videoWrapper iframe {
position: absolute;
max-width:560px;
max-height:315px;
width: 95%;
height: 95%;
left:0;
right:0;
margin:auto;
}
Javascript：
// Get the modal
var modal = document.getElementById('trailerdivbox');
// Get the button that opens the modal
var btn = document.getElementById("watchbutton");
// When the user clicks the button, open the modal
btn.onclick = function() {
modal.style.display = "block";
}
var trailerbox = document.getElementById("close");
trailerbox.onclick = function() {
modal.style.display = "none";
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}
}
添加?autoplay=1到您的 iframe src。
和复位的src停止录像。
要iframe仅在单击按钮时加载源，而不是在文档加载时加载它，您应该src在playVideo()函数上设置属性。
为此，您可以向iframe( data-src)添加一个新属性，该属性将存储视频 URL，然后在需要时访问它的值。
// Get the modal
var modal = document.getElementById('trailerdivbox');
// Get the button that opens the modal
var btn = document.getElementById("watchbutton");
function playVideo() {
var video = document.getElementById('video');
var src = video.dataset.src;
video.src = src + '?autoplay=1';
}
function resetVideo() {
var video = document.getElementById('video');
var src = video.src.replace('?autoplay=1', '');
video.src = '';
video.src = src;
}
// When the user clicks the button, open the modal
btn.onclick = function() {
modal.style.display = "block";
playVideo();
}
var trailerbox = document.getElementById("close");
trailerbox.onclick = function() {
modal.style.display = "none";
resetVideo();
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
resetVideo();
}
