    mail($to, $subject, $message, $headers); //This method sends the mail.

你是什么意思“所需”没有工作..检查请求是否被发送 –

你使用什么浏览器？你确定它支持HTML5的'required'吗？ – Steve

你使用什么浏览器？ 'required'是一个HTML5属性，旧版浏览器可能不支持它。 – Barmar

这只是我的看法，但我会使用PHP来检查输入字段是否为空。

只要有一个if语句来查看他们是否填写就行了。

<?php 

// Here we get all the information from the fields sent over by the form. 
$name = $_POST['name']; 
$email = $_POST['email']; 
$message = $_POST['message']; 

if($name=='' || $email=='' || $message=='') { //Make sure all of the fields are not empty 
echo "Please fill in all of the fields"; 
} 
else { //If they are filled in, process the rest of the form 

$to = '[email protected]'; 
$subject = 'the subject'; 
$message = 'FROM: '.$name.' Email: '.$email.'Message: '.$message; 
$headers = 'From: [email protected]' . "\r\n"; 

if (filter_var($email, FILTER_VALIDATE_EMAIL)) { // this line checks that we have a valid email address 
    mail($to, $subject, $message, $headers); //This method sends the mail. 
    echo "Your email was sent!"; // success message 
}else{ 
    echo "Invalid Email, please provide an correct email."; 
} 
} 
?>
