Question

在我的页面内部工作，不刷新页面，它会向数据库发送我想要的内容，但是，当它发送时，或者根据错误有错误时应突出显示该框但是它没有按＆＃39;吨。每当我按下按钮时，我都会在控制台中收到此错误：

的index.php：

<!DOCTYPE html>

  <head>
    <meta charset="utf-8">
    <title></title>

    <script>
      $(document).ready(function(){
        $("form").submit(function(){
          event.preventDefault();
          var name = $("#mail-name").val();
          var email = $("#mail-email").val();
          var gender = $("#mail-gender").val();
          var message = $("#mail-message").val();
          var submit = $("#mail-sendEmail").val();

          $(".form-message").load("mail.php", {

?>

<script>

  }else if(errorEmail == true){
    $("#email").addClass("input-error");
  }

  if(errorEmpty == false && errorEmail == false){
    $("#name, #email, #message").val('');
  }

</script>

它没有调用mail.php脚本中的脚本。

Ajax脚本没有调用
