Php echo功能不适用于联系表单上的ajax

Question

最近我一直在尝试制作一个带有recaptcha 支持的html 联系表单，并在php 上使用echo 来显示失败和成功消息，但是我不知道为什么它没有与css 一起出现。 但是当我在主网站上使用代码<p class="alert alert-warning">Please check the the captcha form.</p> 时，它可以工作。 Error image

邮件.php

    <?php

    if ($_SERVER["REQUEST_METHOD"] == "POST") {

        // access
        $secretKey = '6LcEPdAaAAAAAHP4NLmyC1UNC5Ce9_0__gTaF5Im';
        $captcha = $_POST['g-recaptcha-response'];

        if(!$captcha){
          echo '<p class="alert alert-warning">Please check the the captcha form.</p>';
          exit;
        }

        # FIX: Replace this email with recipient email
        $mail_to = "soporte@steycian.com";
        
        # Sender Data
        $subject = trim($_POST["subject"]);
        $name = str_replace(array("\r","\n"),array(" "," ") , strip_tags(trim($_POST["name"])));
        $email = filter_var(trim($_POST["email"]), FILTER_SANITIZE_EMAIL);
        $phone = trim($_POST["phone"]);
        $message = trim($_POST["message"]);
        
        if ( empty($name) OR !filter_var($email, FILTER_VALIDATE_EMAIL) OR empty($phone) OR empty($subject) OR empty($message)) {

Answer 1

因为某处，您的 ajax 代码可能会像这样插入 HTML：

$('.ajax-response').text(result);

应该是什么时候

$('.ajax-response').html(result);
