javascript - 如何在 Bootstrap 模式中编写表单的成功消息？

Question

已解决

好的，我使用 AJAX 解决了问题，但我不得不删除我的 WordPress，因为它无法使用它，所以稍后我将通过单独的目录上传回来。幸运的是，我的索引不需要它。工作代码是CodexWorld 。我希望我能帮助那些无助的人。

我整天都在寻找解决方案，但我在任何地方都找不到相关的解决方案。这里的其他类似问题都是老问题，也许有新的解决方案。

所以我是第一次使用Bootstrap(文件是关于Wordpress的主题)。我开始在模态中构建联系表单，如果我点击“提交”，窗口将关闭，我会收到电子邮件，但仅当我重新打开它时才会显示成功消息。我尝试了在互联网上找到的所有解决方案。

我对javascript和jquery不熟悉，不知道如何使用。

在我实现的页脚中:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>

索引中有 Modal 的形式:

 <!-- Modal -->
    <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
      <div class="modal-dialog" role="document">
        <div class="modal-content">
    <form class="form-horizontal clearfix" id="contact-form" name="contact" role="form" method="post" action="index.php">
          <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
            <h4 class="modal-title" id="myModalLabel">Küldj egy üzenetet</h4>
          </div>
          <div class="modal-body">

</div>


<div class="form-group">
    <label class="col-sm-2 control-label">Itt landol</label>
    <div class="col-sm-10">
      <input class="form-control" id="disabledInput" type="text" placeholder="hello@kanizsaipatricia.hu" disabled>
    </div>
  </div>

    <div class="form-group">
        <label for="name" class="col-sm-2 control-label">Név</label>
        <div class="col-sm-10">
            <input type="text" class="form-control" id="name" name="name" placeholder="Minta János" value="<?php echo htmlspecialchars($_POST['name']); ?>">
            <?php echo "<p class='text-danger'>$errName</p>";?>
        </div>
    </div>
    <div class="form-group">
        <label for="email" class="col-sm-2 control-label">Email</label>
        <div class="col-sm-10">
            <input type="email" class="form-control" id="email" name="email" placeholder="valaki@email.hu" value="<?php echo htmlspecialchars($_POST['email']); ?>">
            <?php echo "<p class='text-danger'>$errEmail</p>";?>
        </div>
    </div>
    <div class="form-group">
        <label for="message" class="col-sm-2 control-label">Üzenet</label>
        <div class="col-sm-10">
            <textarea class="form-control" placeholder="Ide írd az üzenetet" rows="4" name="message"><?php echo htmlspecialchars($_POST['message']);?></textarea>
            <?php echo "<p class='text-danger'>$errMessage</p>";?>
        </div>
    </div>
        </div>

                        <?php echo $result; ?>

      <div class="modal-footer">
        <button type="button" class="btn btn-cancel hvr-fade" data-dismiss="modal">Mégsem</button>
        <input type="submit" id="submit" name="submit" data-toggle="modal" data-target="#resultModal" value="Elküldöm" class="btn btn-info hvr-wobble-horizontal">
    </div>  
</pop:form>
      </div>
    </div>

表单背后的php代码:

if (isset($_POST["submit"])) {
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['message'];
    $from = 'Üzenetküldő űrlap'; 
    $to = 'hello@kanizsaipatricia.hu'; 
    $subject = 'Új üzenet formon keresztül';

    $body = "Feladó: $name\n E-Mail: $email\n Üzenet:\n $message";

    // Check if name has been entered
    if (!$_POST['name']) {
        $errName = 'Kérlek, add meg a neved!';
    }

    // Check if email has been entered and is valid
    if (!$_POST['email'] || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
        $errEmail = 'Nem érvényes e-mail cím!';
    }

    //Check if message has been entered
    if (!$_POST['message']) {
        $errMessage = 'Nem írtál üzenetet.';
    }


// If there are no errors, send the email
if (!$errName && !$errEmail && !$errMessage) {
    if (mail ($to, $subject, $body, $from)) {
        $result='<div class="alert alert-success noshadow">Elküldve.</div>';
    } else {
        $result='<div class="alert alert-danger noshadow">Sajnálom, hiba lépett fel az üzenet küldése közben. Próbáld újra!</div>';
    }
}
}

我对任何语言的任何解决方案都持开放态度!请帮忙!

发送联系请求电子邮件 (submit_form.php)

<?php

    // Submitted form data

        </tr>
    </table>';

    // Set content-type header for sending HTML email
    $headers = "MIME-Version: 1.0" . "\r\n";
    $headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";

    // Additional headers
    $headers .= 'From: CodexWorld<sender@example.com>' . "\r\n";

    // Send email
    if(mail($to,$subject,$htmlContent,$headers)){
        $status = 'ok';
    }else{
        $status = 'err';
    }

    // Output status
