禁用HTML文本框以进行输入。 “渲染”按钮工作正常，onClick显示已定义的几何体。我尝试将render.domElement更改为页面上的不同元素，如容器，信息，父级和场景。但是无法找出为什么禁用文本框？

由于轨迹球控制，它阻止了每次鼠标输入的默认操作。
这可能是重复的 Three.JS -- conflict Camera controls with a textbox in a scene

晚了，但这适合我。您应该启用mousedown Listener：
发件人：
document.addEventListener( 'mousedown', onDocumentMouseDown, false);
以
document.addEventListener( 'mousedown', onDocumentMouseDown, true);
