我正在从事一个电子商务项目，我想在其中使用 AR.JS 显示图像。图像是普通的二维 jpeg。我只想能够显示在我的背景上。我已经构建了一个模态并在其中包含了 A 型框架。图像旋转显示，而不是在主图像的顶部。
其次，代码会自动呈现在整个页面上，而不仅仅是模式。有没有一种方法只有在模态出现时才渲染它，然后用模态关闭它。
非常感谢您的帮助。
打开模式

<script>
// Get the modal
var modal = document.getElementById('myModal');
// Get the button that opens the modal
var btn = document.getElementById("myBtn");
// Get the <span> element that closes the modal
//var span = document.getElementsByClassName("close1")[0];
var span = document.getElementById("myModalclose");
// When the user clicks on the button, open the modal
btn.onclick = function() {
modal.style.display = "block";
}
// When the user clicks on <span> (x), close the modal
span.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";
}
}
