// 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");

您可以将data-src
属性更改为src
,然后在点击该按钮时,将data-src
设置为// 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";
}
}

最简单的方法是在点击&#34;观看预告片&#34;时添加src
属性。按钮! :)
// 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";
//Add "src" attribute by getting the video and setting it with setAttribute.
document.getElementsByClassName('trailervideo')[0].setAttribute('src', 'https://www.youtube.com/embed/TDwJDRbSYbw');
}
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";
}
}
