尝试使用 AR.JS 显示 jpeg 图像并且仅在单击按钮时显示

Question

我正在从事电子商务项目，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，代码自动呈现在整个页面上，而不仅仅是模式。有没有办法只在模态出现时渲染它，然后用模态关闭它。

非常感谢您的帮助。

打开模式

<!-- Modal or popup -->

 <div id="myModal" class="modal">


  <!-- Modal content -->
  <div class="modal-content">
    <span  id="myModalclose" class="close">&times;</span>


   </div>


 <a-scene embedded arjs>
    <a-assets>
        <img id="transpImage" src="${productFullImage}" alt="<c:out value="${fullImageAltDescription}" escapeXml="${env_escapeXmlFlag}"/>" title="<c:out value="${fullImageAltDescription}" escapeXml="${env_escapeXmlFlag}"/>" class="product_main_image"/>
    </a-assets>
    <a-image  rotation="0 0 0" src="#transpImage"></a-image>
