同一页面上的Ajax jQuery Html电子邮件表单输出

Question

我希望在页面上输出PHP消息，而不是在新屏幕上转到PHP。这是我的代码。

PHP

<?php 
// VALUES FROM THE FORM 
$name = $_POST['name']; 
$email = $_POST['email']; 
$subject = $_POST["subject"]; 
$message = $_POST['message']; 

// Only process POST reqeusts. 
if ($_SERVER["REQUEST_METHOD"] == "POST") { 
    // Get the form fields and remove whitespace. 
    $name = strip_tags(trim($_POST["name"])); 
    $name = str_replace(array("\r","\n"),array(" "," "),$name); 
    $email = filter_var(trim($_POST["email"]), FILTER_SANITIZE_EMAIL); 
    $message = trim($_POST["message"]); 

    // Check that data was sent to the mailer. 
    if (empty($name) OR empty($message) OR !filter_var($email, FILTER_VALIDATE_EMAIL)) { 
     // Set a 400 (bad request) response code and exit. 
     http_response_code(400); 
     print "Oops! There was a problem with your submission. Please complete the form and try again."; 
    } 

    // Set the recipient email address. 
    // FIXME: Update this to your desired email address. 
    // CREATE THE EMAIL 
    $headers = "Content-Type: text/plain; charset=iso-8859-1\n"; 
    $headers .= "From: $name <$email>\r\n"; 
    $recipient = "myemail@outlook.com"; 
    $subject = "Message to Me - $subject"; 
    $message = wordwrap($message, 1024); 

    // Send the email. 
    if (mail($recipient, $subject, $message, $headers)) { 
     // Set a 200 (okay) response code. 
     http_response_code(200); 
     print "Thank You! Your message has been sent."; 
    } else { 
     // Set a 500 (internal server error) response code. 
     http_response_code(500); 
     print "Oops! Something went wrong and we couldn't send your message."; 
    } 
} else { 
    // Not a POST request, set a 403 (forbidden) response code. 
    http_response_code(403); 
    print "There was a problem with your submission, please try again."; 
} 

HTML

<form id="form_contact" class="submit-form" method="post" action="process.php"> 

    <!--Name and Email Field Box--> 
    <div class="row"> 
     <div class="col-sm-6 addpadding">

       <label>Your email</label> 
       <span></span> 
      </div> 
     </div> 
    </div> 

    <!--Subject Field Box--> 
    <div class="box text-input"> 
     <input id="subject" type="text" name="subject" required /> 
     <label>Your subject</label>

    <!--Submit Button--> 
    <div class="button raised purple"> 
     <input id="submit_message" type="submit" value="Send Your Message"/> 
    </div> 

    <span class="loading"><i class="fa fa-spinner fa-pulse"></i></span> 

    <div class="clearfix"></div> 

    <div id="reply_message"></div> 

</form> 

JS

$("#submit_message").on("click", function() { 
$('#reply_message').removeClass(); 
$('#reply_message').html('') 
var regEx = ""; 

// validate Name 
var name = $("input#name").val(); 
regEx=/^[A-Za-z .'-]+$/; 
if (name == "" || name == "Name" || !regEx.test(name)) { 
    $("input#name").val(''); 
    $("input#name").focus(); 
    return false; 
} 

// validate Email 
var email = $("input#email").val(); 
regEx=/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/; 
if (email == "" || email == "Email" || !regEx.test(email)) {

    $("input#email").focus(); 
    return false; 
}

    $("input#subject").focus(); 
    return false; 
} 

// validate Message 
var mymessage = $("textarea#mymessage").val(); 
if (mymessage == "" || mymessage == "message" || mymessage.length < 2) { 
    $("textarea#message").val(''); 
    $("textarea#message").focus(); 
    return false; 
} 
    return valid; 

var dataString = 'name='+ $("input#name").val() + '&email=' + $("input#email").val() + '&subject='+ $("input#subject").val() + '&mymessage=' + $("textarea#mymessage").val(); 

$('.loading').fadeIn(500); 

// Send form data to mailer.php 
$.ajax({ 
    type: "POST", 
    url: "process.php", 
    data: dataString, 
    success: function() { 
     $('.loading').hide(); 
     $('#reply_message').addClass('list3'); 
     $('#reply_message').html("<span>Mail sent successfully</span>") 
     .hide() 
     .fadeIn(1500); 
     $('#form_contact')[0].reset(); 
     } 
    }); 

在此先感谢。

1st。你的最后一个代码块没有完成它丢失了}

2nd。如果你使用的是Ajax，你应该停止点击事件传播

3rd。如果提交按钮类型是submit和你正在使用的Ajax你应该返回false最终

$("#submit_message").on("click3rd", function(e) { 
    // stop event propagation 
    // if you are return false eventually this would not necessary 
    e.stopPropagation() 

    $('#reply_message').removeClass(); 
    $('#reply_message').html('') 
    var regEx = ""; 

    // validate Name 
    var name = $("input#name").val(); 
    regEx = /^[A-Za-z .'-]+$/; 
    if (name == "" || name == "Name" || !regEx.test(name)) { 
     $("input#name").val(''); 
     $("input#name").focus(); 
     return false; 
    } 

    // validate Email 
    var email = $("input#email").val(); 
    regEx = /^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/; 
    if (email == "" || email == "Email" || !regEx.test(email)) { 
     $("input#email").val(''); 
     $("input#email").focus(); 
     return false; 
    } 

    // validate Subject 
    var subject = $("input#subject").val(); 
    regEx = /^[A-Za-z0-9 .'-]+$/; 
    if (subject == "" || subject == "subject" || !regEx.test(subject)) { 
     $("input#subject").val(''); 
     $("input#subject").focus(); 
     return false; 
    } 

    // validate Message 
    var mymessage = $("textarea#mymessage").val(); 
    if (mymessage == "" || mymessage == "message" || mymessage.length < 2) { 
     $("textarea#message").val(''); 
     $("textarea#message").focus(); 
     return false; 
    } 

    var dataString = 'name=' + $("input#name").val() + '&email=' + $("input#email").val() + '&subject=' + $("input#subject").val() + '&mymessage=' + $("textarea#mymessage").val(); 

    $('.loading').fadeIn(500); 

    // Send form data to mailer.php 
    $.ajax({ 
     type: "POST", 
     url: "process.php", 
     data: dataString, 
     success: function() { 
      $('.loading').hide(); 
      $('#reply_message').addClass('list3'); 
      $('#reply_message').html("<span>Mail sent successfully</span>") 
       .hide() 
       .fadeIn(1500); 
      $('#form_contact')[0].reset(); 
     } 
    }); 

    // return false to stop form submit, because you are using ajax already 
    return false 
}
