Javascript AJAX表单未显示成功或错误消息

Javascript AJAX表单未显示成功或错误消息,javascript,php,jquery,html,ajax,Javascript,Php,Jquery,Html,Ajax,我以前问过这个问题,但我还是不明白。我做了一些改变,但不幸的是我仍然没有得到任何运气。表单本身可以工作,但当用户尝试发送表单时,它也应该显示错误或成功消息。但是它没有显示消息,而是发送表单而不显示它。看看我的代码: HTML <form action="" method="POST"> <ul class="form-style-1"> <li> <input type="text" id="mail-n

PHP(位于PHP文件中)

if(isset($\u POST['submit'])){
$email_to=“#””;
$email_subject=“#””;
$name=$_POST['name'];
$lastname=$\u POST['lastname'];
$email=$_POST['email'];
$phone=$_POST['phone'];
$subject=$_POST['subject'];
$information=$_POST['information'];
$errorEmpty=false;
$errorEmail=false;
if(空($name)| |空($email)| |空($subject)| |空($information)){
回音“欢迎光临!”;
$errorEmpty=true;
}
elseif(!filter\u var($email,filter\u VALIDATE\u email)){
回音“Geefeen geldig电子邮件!”;
$errorEmail=true;
}
否则{
$formcontent=“Naam:$name\n\n Achternaam:$lastname\n\n Email:$Email\n\n Telefoon:$phone\n\n Onderwerp:$subject\n\n Informatie:$information”;
$mailheader=“From:”..$\u POST[“email”]。“\r\n”;
$headers=“From:”.htmlspecialchars($\u POST['name'])。“\r\n”;
$headers.=“回复:”.$\u POST['email']。“\r\n”;
$headers.=“MIME版本:1.0\r\n”;
$headers.=“内容类型:text/html;字符集=ISO-8859-1\r\n”;
邮件($email_to,$subject,$formcontent,$mailheader);
echo“电子邮件已发送!”;
}
}
这是我使用的AJAX脚本:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>

这里发生了两个javascript事件。您有表单提交事件,该事件由type=“submit”按钮触发。该按钮触发了一个
onclick
事件。相反,您可以向表单中添加一个Id,并将其列在一个
onSubmit
事件中,例如

<form id="email-form">
...
</form>

$("#the-form").submit(function(event) {
  event.preventDefault();
  ...
});

...
$(“#表格”)。提交(功能(事件){
event.preventDefault();
...
});

然后您应该能够发出
ajax
请求
