我的表单提交被阻止，因为框架已被沙盒化且未设置“允许表单”权限

我正在尝试为 Hubspot 构建自定义表单和提交帖子。

我有以下代码

HTML

<head>
<script src="prezzi-form-submit.js"></script>
</head>
<body>

  <form class='form-inline' id='my-custom-form'>
    <div class="form-group">
      <input type='email' class='form-control' placeholder='Your email address' required>
    </div>
    <button class="btn btn-primary" type='submit'>Sign up</button>
  </form>

  <!-- Actual form that gets submitted to HubSpot -->
  <div class="hidden" id='hubspot-form'>
    <script charset="utf-8" src="//js.hsforms.net/forms/current.js"></script>
    <script>
      hbspt.forms.create({
        portalId: 'my-portal-id',
        formId: '92b9b82a-0da2-4e23-8a30-04541c05ce6d',
        onFormReady: function($form) {
          $form.attr('target', 'hubspot-iframe');
        }
      });
    </script>

    <!-- iFrame that data will get submitted to. This hack stops the page redirect. -->
    <iframe name="hubspot-iframe" id="hubspot-iframe" sandbox="allow-forms"></iframe>
  </div>
</body>

JS (prezzi-form-submit.js)

// // Send form data to HubSpot from the client.
function submitToHubSpot(data) {
  var $form = $('#hubspot-form form'),
      k;

  // Loop through each value and find a matching input.
  // NOTE: Doesn't support checkbox/radio.
  for (k in data) {
    $form.find("input[name='" + k + "']").val(data[k]);
  }

  $("form input:submit").trigger("click");
}

// Here's how you'd use this.
$('#my-custom-form').on('submit', function() {
  var formData = {};
  $(this).serializeArray().forEach(function(data) {
    formData[data.name] = data.value;
  });

  submitToHubSpot(formData);

  // We sent the data. Now do whatever else you want.
  alert('Gee, thanks Jonathan! Now I can focus on onboarding my customers with Appcues!');
  window.location.href = 'http://appcues.com';
