Campaign Monitor表单保持重定向

Question

新版Campaign Monitor订阅代码的工作方式不同。如您所见，代码提供了一个负责发送数据的js文件（copypastesubscribeformlogic.js）。

发生了什么变化？

以前，只有一个静态请求到CM端点订阅用户，并且很容易通过ajax请求订阅。现在，它需要两个单独的请求来订阅用户。第一个请求由ajax完成，由CM提供（js文件copypastesubscribeformlogic.js处理此请求）。

我的问题：我想在没有页面刷新或重定向的情况下在同一页面上加载成功消息，但它会一直重定向到默认的CM谢谢页面。

我的表格：

<form id="subForm" class="js-cm-form" action="https://www.createsend.com/t/subscribeerror?description=" method="post" data-id="XXXX-XXX-XX-X">
<p>       
    <input placeholder="Full Name" id="fieldName" name="cm-name" type="text" />
</p><br/>
<p>        
    <input placeholder="Email" id="fieldEmail" class="js-cm-email-input" name="cm-fhutty-fhutty" type="email" required /> 
</p><br/>
<p>
    <label for="fieldeihjlu">How did you hear of us?</label><br />
    <select  id="fieldeihjlu" name="cm-fo-eihjlu">
        <option value="1985454">Word of Mouth</option>
        <option value="1985450">Social Media</option>
        <option value="1985451">Press</option>
        <option value="1985452">Web Search</option>
        <option value="1985453">Sales and Marketing Activities</option>            
    </select>
</p>
<p>         
    <input class="js-cm-submit-button" type="submit" value="Submit">
</p>
</form>
<script type="text/javascript" src="https://js.createsend1.com/javascript/copypastesubscribeformlogic.js"></script>

成功消息（与表单相同的页面）：

<div id="success">
<h2 class='thank-you'>Thank you for subscribing</h2>
</div>

然后根据这个LINK我添加了以下js：

var campaign = (function (c, d, $) {

var body,
  form,
  form_id,
  config,
  successMessage;

c.init = function () {

body = $('body');
form = body.find('#' + config.formSelector);
form_id = form.attr('data-id');
successMessage = $('#' + config.successSelector);
successMessage.hide();

// On form submit.
form.submit(function (evt) {

  // Disable default form submit.
  evt.preventDefault();

  // Get e-mail value.
  email = $('input[type=email]', form).val();

  // Build request data for tokenRequest.
  request_data = "email=" + encodeURIComponent(email) + "&data=" + form_id;

  // Prepare tokenRequest.
  tokenRequest = new XMLHttpRequest();
  tokenRequest.open('POST', 'https://createsend.com//t/getsecuresubscribelink', true);
  tokenRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
  tokenRequest.send(request_data);

  // Ready state.
  tokenRequest.onreadystatechange = function() {
    if (this.readyState === 4) {
      if (this.status === 200) {
        // Having token and new submit url we can create new request to subscribe a user.
        subscribeRequest = new XMLHttpRequest();
        subscribeRequest.open('POST', this.responseText, true);
        subscribeRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        subscribeRequest.send(form.serialize());
        // On ready state call response function.
        subscribeRequest.onreadystatechange = function() {
          c.response(subscribeRequest);
        }
      } else {
        c.response(tokenRequest);
      }
    }
  }
});
};

// Handle ajax response.
c.response = function(request) {
if (request.readyState === 4) {
  if (request.status === 200) {
    successMessage.show('slow');
  } else {
    form.prepend('<p class="error">' + config.errorMessage + '</p>');
  }
}
};

// Private
config = {
formSelector: 'form',
errorMessage: 'There was a problem submitting this form. Please try later.',
successSelector: 'success',
};

return c;

}(campaign || {}, {}, jQuery));

(function () {
 campaign.init();
})(jQuery);

*在页面加载时，我没有得到任何Console错误。

*在提交时我收到错误：Refused to execute script from https://www.createsend.com/t/subscribeerror?description=..... because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled，

但它仍然执行到默认的CM谢谢页面。
