我编写了一个用于注册网站的弹出窗口。它工作正常，除了一个方面 - 当用户未能提供所有必要的信息时，弹出窗口将消失但随后重新出现并显示错误消息。同样，如果用户提供所有信息并单击发送，消息将成功发送，但弹出窗口消失，然后重新出现并显示成功消息。当用户单击关闭时，弹出窗口将关闭并保持原状。
我一直在检查代码，但我就是找不到它为什么消失然后又出现的原因。我希望它留在那里并显示错误消息或成功消息，然后仅在用户单击“关闭”时消失。这是以下代码 - HTML、CSS、JS 和 PHP
这是 website这样您就可以看到它的实际效果。
我感谢所有建议!谢谢

最佳答案
您的表单提交请求基本上重新加载页面，因此再次启动 window.onload 函数
关于javascript - 我无法弄清楚为什么弹出窗口会在出现错误或发送时消失并重新出现，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44608686/
