我试图通过模式提交表单，但我有问题，因为页面重新加载提交，我已经阻止了默认操作，但页面仍然重新加载。

我不知道为什么这会给我带来麻烦，有人能帮我吗？

HTML代码：

<body>
    <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#myModal">
        Launch demo modal
      </button>
    <!--    Modal Area-->
    <!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
    <div class="modal-dialog modal-xl" role="document">
      <div class="modal-content">
        <div class="modal-header">
          <div class="close text-secondary" data-dismiss="modal" aria-label="Close">
              <button type="button" class="close" aria-label="Close">
                <span aria-hidden="true">Close</span>
              </button>
            </div>
            <div class="text-secondary font-weight-normal info" id="info"></div>
        </div>
          
        <div class="modal-body">

我制作了一个jsfiddle来向您展示如何获取FormData对象：

https://jsfiddle.net/ac81hk97/

$('form').on('submit', function(ev) {
  ev.preventDefault();
    const $form = $(this);
  const formData = new FormData($form[0]);
  
  const formObj = {};
  for (var key of formData.keys()) {
   console.log(key); 
   formObj[key] = formData.get(key);
  }
  
  const json = JSON.stringify(formObj);
  $('#json').text(json);
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form id="222" action="">
  <input type="text" name="first_input">
  <input type="text" name="second_input">
  <button>submit</button>
</form>
<div id="json"></div>

如果您查看this answer，就会看到如何使用form.serialize()提交它
