防止模式在页面加载过程中闪烁

我已经浏览了其他几篇与此相关的帖子，但遗憾的是，我无法找到一个有效的解决方案。

非常感谢您的帮助。

我正在尝试在加载页面时短暂停止模式闪烁可见性。我有一个使用OpenwebGL加载的3D模型，所以需要几秒钟的时间来加载。开头闪烁的模态看起来不整洁。

我不确定在三维模型完成加载之前阻止模态加载的最佳方法。

这是页面的HTML代码：

我又来了。

好的，感谢论坛上关于这个话题的很多问题，但没有找到一个简单的答案。

我最终从各种想法中结合起来，找到了一个解决方案。

因此，对于其他试图在未来解决此问题的人，请尝试以下操作：

将模态div放在一个新的div中。在标题中使用样式注释使父div不可见。将其添加到打开的正文注释onload="showdiv((；"中，然后在您的身体底部添加一个函数showdiv脚本。

这是上面相同的HTML，并进行了新的调整：
