    <a-scene main>
      <a-sphere position="0 2 -5" radius="1.25" color="#EF2D5E"> </a-sphere>
 <!-- ... -->

      <a-camera id="camera" camera rotation>
        <a-entity
          id="cursor"
          cursor="fuse:false"
          position="0 0 -1"
          material="color: #111;"

        >
        </a-entity>
      </a-camera>
//simple event on click
 document.querySelector("a-box").addEventListener("click", () => {
   alert("box");
});```

推荐答案

您所描述的行为是预期的.当通过WebXR进入沉浸式模式时，浏览器会禁用触摸事件，Chrome 79+就是这种情况，并且内容通过 https 提供.在工作中有新的API可以在AR中呈现时实现交互性.您可以在此博客文章中找到其他详细信息: https://aframe.io/blog/webxr-ar-module/

The behavior you described is expected. Touch events are disabled by the browser when entering immersive mode via WebXR as it's the case for Chrome 79+ and content served over https. There are new APIs in the works to enable interactivity while presenting in AR. You can find additional details in this blog post: https://aframe.io/blog/webxr-ar-module/

在没有本机WebXR实现的设备上，VR模式依赖于全屏API，并且可以使用touchevents.

On devices that don't have a native WebXR implementation VR mode relies on the full screen API and touchevents are available.

我不建议在VR中依赖屏幕输入，而是使用基于保险丝的光标

I don't recommend relying on screen input while in VR and use a fuse based cursor
