ain. When running in a spec file, setting `window.disableAjaxHashChange = true`
  will disable the hash route change so the ajax call is fully processed by the ajax
  feature instead of  the SPA feature.
</div>
<div><button id="sendAjax">Send Ajax</button></div>
<script>
  window.disableAjaxHashChange = false
  document.getElementById('sendAjax').addEventListener('click', sendAjax)
</script>
</body>
</html>
