我正在按照指南构建引导联系表单并通过mail.php提交，而无需使用ajax重新加载页面。在尝试实现ajax之前，我能够让表单工作。我被卡住了，因为指令并不清楚哪些代码确实需要被替换以及新代码应该去哪里。以下是我正在遵循的指南和我被困的部分的链接：
Sending email without reloading page using AJAX
这是我尝试使用的网站：CRANE TECH. NET
我对php不太熟悉所以我认为这就是我搞砸了。
以下是我正在使用的确切代码：

答案 0 :(得分：1)
你的主要问题是在php代码中缺少semcolon（;）和第15行的结尾。
您的网站使用的是JQuery Slim，$.ajax未包含在超薄版本中，因此您会收到错误消息。要解决这个问题，只需要包含完整的JQuery，或者在没有JQuery的情况下执行ajax
您可能还想摆脱这条线：
document.getElementById('contact-form').submit();
因为当您手动提交数据时，它会导致重定向
你应该删除这些行，因为你已经设置了它们：
$name = $_POST['name'];
$email = $_POST['email'];
$clientPhone = $_POST['clientPhone']
$message = $_POST['message'];
$subject = $_POST['subject'];
如果您已经在使用JQuery，那么您应该使用它 - 而不是这样做：
document.getElementById('status')
你应该使用：
$('#status')
