仅当单击“观看视频”按钮时,我才需要 YouTube 视频 Iframe。目前,当页面加载时,视频 iframe 在后台加载。
注意:我的意思不是在单击按钮时播放视频。我的意思是,在单击按钮时加载 iframe

// 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";
}
}

最佳答案
您可以将src
属性更改为data-src
,然后当您单击按钮时,将src
设置为data -src
// Get the modal
var modal = document.getElementById('trailerdivbox');
// Get the button that opens the modal
var btn = document.getElementById("watchbutton");
var trailer = document.getElementById('trailervideo');
// When the user clicks the button, open the modal
btn.onclick = function() {
modal.style.display = "block";
trailer.setAttribute('src', trailer.getAttribute('data-src'));
}
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";
}
}
