Access to failed XHR object?

General questions
1

Does Piwik provide a status for when a request to the Piwik server has failed, like in case of being blocked by an AdBlocker. This can be helpful in asking the users to disable blockers.

Thanks

It might work to just listen to the global ajax status, but I’m not sure and have not tested it. We ourself simply check if the JS itself gets loaded.

<!-- AdBlock Detection Start -->
<script defer="defer" type="text/javascript" src="../include/js/adblock_detection/piwik.js" onerror="$('#msg_blocker').removeClass('hidden');"></script>
<script defer="defer" type="text/javascript" src="../include/js/adblock_detection/_advertisement.js" onerror="$('#msg_blocker').removeClass('hidden');"></script>
<script defer="defer" type="text/javascript" src="../include/js/adblock_detection/ads.js?" onerror="$('#msg_blocker').removeClass('hidden');"></script>
<!-- AdBlock Detection End -->
