这似乎确实是一个受欢迎的问题！首先，我真诚地为重复这个问题道歉。我已经尝试了在不同问题中使用的几种修复方法，但还没有找到任何可以解决我的问题的方法。
我创建了一个网站，基本上想从联系表中向我发送查询。我将尝试定义我的问题： 1. 我期待出现一条错误消息，上面写着“名称是必填字段”或类似内容，但事实并非如此。2. 当按下提交时，页面将我带到一个空白页面，该页面将我定向到我服务器上的 mail_form.php。
值得注意的是，我的服务器是 123-reg，他们说他们确实允许用户脚本，但也提供了他们自己的使用示例——我试过这个没有用。
我不是 100% 确定你会要求看什么，所以我会提供我的 jsfiddle 和相关位：
