为什么我收到错误的javascript消息

我的javascript/php页面有问题： 当有人在我的网站上连接或注册时，我发出了java系统警报。我可以正确连接我的帐户，但有错误的消息（我让您查看我的代码）

现在，我的注册PHP表单：

<form class="signup-form" id="register_me" action="<?= $site['lien']; ?>/app/actions/inscription.php" method="post" role="form" autocomplete="off">
  <h3 class="Ang-message">Inscris-toi dès maintenant sur <span><?= $site['nom']; ?></span>!</h3>
  <input type="text" name="bean_name" id="register__input" placeholder="Nom d'utilisateur" required>
  <input type="email" name="bean_email" id="register__input" placeholder="Adresse mail" required>
  <input type="password" name="bean_password" id="register__input" placeholder="Mot de passe" required>
  <input type="password" name="bean_repassword" id="register__input" placeholder="Confirmer votre mot de passe" required>

  <button type="submit" id="login__submit">Finaliser l'inscription</button>
  <a href="index" id="btn__register">Annuler</a>
</form>

！

尝试使用

html.trim（）

，PHP脚本回显的字符串周围可能有额外的空格。如果这不能解决问题，请在发送AJAX请求时转到“网络”选项卡，查看响应以确保没有额外内容。感谢您的帮助，我让您检查我的控制台：那不是“网络”选项卡。转到网络选项卡，提出AJAX请求，单击

inscript.php

URL，单击

Response

查看响应。我做到了，我看到了：preview.ibb.co/c3PpVK/sans_titre.png
