单击SUBMIT按钮后出现错误：

ERRORLOG

该脚本在其他网站上运行。但这一次它不起作用：（

JS

$(document).ready(function(){
  $("#teilnahme").validate({
    rules: {
      inputVorname: { required: true }
    },
    messages: {
      inputVorname: { required: "Bitte tragen Sie Ihren Vornamen ein." }
    },
    submitHandler: function(form) {
      theUrl = 'teilnahme.php';
      var params = $(form).serialize();

      $.ajax ({
        type: "POST",
        url: theUrl,
        data: params,
        processData: false,
        async: false,
        success: function(result) {
          $("#sendbutton").fadeOut(100).hide(function(){
          $("#successbutton").fadeIn(100).show(function(){
          $(".result").html(data);
          });
          });
        }
      });
    }
  }); //end validate
});

验证工作。但是submitHandler没有

HTML

<form accept-charset="utf-8" method="post" name="teilnahme" id="teilnahme">
    <div class="form-row">
      <div class="form-group col-md-6">

        <input type="text" class="form-control" id="inputVorname" name="inputVorname" placeholder="Vorname">

      <div class="form-group col-md-6">

          <option>...</option>
        </select>
      </div>
    </div>
    <div class="custom-control custom-radio">
      <input type="radio" id="customRadio1" name="customRadio" class="custom-control-input">
      <label class="custom-control-label" for="customRadio1">2 Übernachtungen, Anreise am Vortag</label>
    </div>
    <div class="custom-control custom-radio">
      <input type="radio" id="customRadio2" name="customRadio" class="custom-control-input">
      <label class="custom-control-label" for="customRadio2">1 Übernachtung, Anreise am 27.04</label>
    </div>
    <div class="custom-control custom-radio">
      <input type="radio" id="customRadio3" name="customRadio" class="custom-control-input">
      <label class="custom-control-label" for="customRadio3">1 Übernachtung</label>
    </div>
    <div class="custom-control custom-radio">
      <input type="radio" id="customRadio4" name="customRadio" class="custom-control-input">
      <label class="custom-control-label" for="customRadio4">Ohne Übernachtung</label>
    </div>
    <button type="submit" id="sendbutton" class="btn btn-success">Teilnehmen</button>
    <button class="btn btn-success" id="successbutton" disabled="disabled"><span class="glyphicon glyphicon-ok" aria-hidden="true"></span></button>
  </form>

我必须解释更多...... 所以我想要一个简单的表格。如果我点击提交按钮，所有信息都必须转到＆＃34; teilnahme.php＆＃34; php脚本将所有内容导入mySQL数据库。也许还有其他解决方案。我不知道。

我在你的错误消息中注意到对jQuery slim的引用：

https://code.jquery.com/jquery-3.2.1.slim.min.js

jQuery slim不包含$ .ajax（）或任何其他相关功能。

如果您希望使用ajax功能，则需要使用完整版的jQuery。

有关“苗条”版本中包含和未包含的内容的详细信息，请参阅最新版（撰写本文时）发行说明：https://blog.jquery.com/2017/03/20/jquery-3-2-1-now-available/

JQuery验证AJAX＆gt; undefined没有属性
