提交联系表单时，在不刷新页面的情况下关闭bootstrap模式

Question

A similar question exists on SO. The reason I'm still posting this is because I am not using any AJAX like the OP of that question. My situation involved the form being submitted to a PHP script that sends the email. Here's the form:

<!-- Modal for contact form -->
    <div class="modal fade" id="contact" role="dialog" tabindex="-1">
      <div class="modal-dialog">
        <div class="modal-content contact-box">
          <form class="form-horizontal" role="form" name="contact-form" id="contact-form" action="contact.php" method="post">
              <div class="modal-header contact-title">
                <img src="bootstrap/img/airmail.png" class="airmail">
                <h4>Let‘s get talking!</h4>
              </div>
              <div class="modal-body contact-body">
                <div class="form-group has-feedback">
                  <label for="contact-name" class="col-xs-2 control-label contact-label">Name</label>
                  <div class="col-xs-10">
                    <input type="text" class="form-control contact-field contact-field-single" name="contact-name" id="contact-name" placeholder="John Doe" OnMouseOver="$(this).focus();">
                    <i class="glyphicon glyphicon-user form-control-feedback input-icon"></i>
                  </div>
                </div>
                <div class="form-group has-feedback">
                  <label for="contact-email" class="col-xs-2 control-label">Email</label>
                  <div class="col-xs-10">
                    <input type="email" class="form-control contact-field contact-field-single" name="contact-email" id="contact-email" placeholder="[e-mail]" OnMouseOver="$(this).focus();">
                    <i class="glyphicon glyphicon-envelope form-control-feedback input-icon"></i>
                  </div>
                </div>
                <div class="form-group">
                  <label for="contact-message" class="col-xs-2 control-label">Message</label>
                  <div class="col-xs-10">
                    <textarea class="form-control contact-field" name="contact-message" rows="10" placeholder="No links please. They are bad and look like spam. Other than that, nothing should be taboo here!" OnMouseOver="$(this).focus();"></textarea>
                  </div>
                </div>
              </div>
              <div class="modal-footer contact-footer">
                <a class="btn btn-default btn-lg contact-close" data-dismiss="modal">Close</a>
                <button type="submit" name="submit" id="submit" class="btn btn-primary btn-lg contact-send">Send</button>
              </div>
          </form>
        </div>
      </div>
    </div>

And here's the PHP this form calls:

$name = $_POST["contact-name"];
$email = $_POST["contact-email"];
$message = $_POST["contact-message"];

$EmailTo = "[e-mail]";
$Subject = "New Message Received";

mail($EmailTo, $Subject, $message, "From: ".$name." <".$email.">");

I am currently not performing any validation. All I need is to dismiss the form when the submit button is clicked. I tried header("Location: {$_SERVER['HTTP_REFERER']}"); in my PHP but that doesn't serve the purpose as it reloads the previous page which I want to avoid at all cost. I also tried adding data-dismiss="modal" to my submit button as suggested by the accepted answer on the referred question but that prevents the submission altogether!

Using Ajax, you can prevent your page for refresh after submit. Remove action="contact.php" from <form> tag. Use below <script></script> to send data to contact.php. For closing modal, you can use either $('.contact-close').click(); Or $('#contact').modal('hide');

<div class="modal fade" id="contact" role="dialog" tabindex="-1">
  <div class="modal-dialog">
    <div class="modal-content contact-box">
      <form class="form-horizontal" role="form" name="contact-form" id="contact-form" method="post">
          .
          .
      </form>
    </div>
  </div>
</div>

<script>
$(document).ready(function (e) {
  $("#submit").on('submit',(function(e) {
    e.preventDefault();
    $.ajax({
      url: "contact.php", // Url to which the request is send
      type: "POST",             // Type of request to be send, called as method
      data: new FormData(this), // Data sent to server, a set of key/value pairs (i.e. form fields and values)
      contentType: false,       // The content type used when sending data to the server.
      cache: false,             // To unable request pages to be cached
      processData:false,        // To send DOMDocument or non processed data file it is set to false
      success: function(data)   // A function to be called if request succeeds
      {
          $('.contact-close').click();
          $('#contact').modal('hide');
          alert("Email Sent Successfully");
      }
    });
  }));
});
</script>
