title: Disable "Changes you made may not be saved" pop-up window
body: <p>I use the following frontend code to export a <code>.csv</code> document.</p>
  
  <p><strong>HTML</strong></p>
  
  <pre><code>  &lt;form id="tool-export" method="post" action="export/"&gt;{% csrf_token %}
      &lt;a id="export-link" class="btn btn-sm btn-primary" href="#"&gt;DOWNLOAD&lt;/a&gt;
    &lt;/form&gt;
  </code></pre>
  
  <p><strong>JS</strong></p>
  
  <pre><code>  $('#export-link').click(function(e) {
      e.preventDefault();
      var link = $(this);
      var form = link.closest('form');
  
      var project_id = proj_id.find(":selected").val();
      var input = $('&lt;input&gt;').attr('type', 'hidden').attr('name', 'project_id').val(project_id);
      form.append($(input));
  
      var project_type = proj_type.val();
      input = $('&lt;input&gt;').attr('type', 'hidden').attr('name', 'project_type').val(project_type);
      form.append($(input));
  
      form.submit();
    });
  </code></pre>
  
  <p>Export works well and I get the correct document. But also I receive the <strong><em>Changes you made may not be saved</em></strong> message after clicking on the export link. How to disable this message? I don't want to see it.</p>
