Trying to figure out Ruby on Rails remote: true callbacks
According to Rails' wiki, the code bellow should work:
<script> $(document).ready(function(){ $('#reportform').on('ajax:success', function(e, data, status, xhr){ $('#reportalert').text('Done.'); }).on('ajax:error',function(e, xhr, status, error){ $('#reportalert').text('Failed.'); }); });</script>A similar code worked for me in Rails 3.2.14 and jquery-rails 3.0.4
Hope it helps.
Since Rails 5.1, response, status, and xhr must be extracted through event.detail see: https://edgeguides.rubyonrails.org/working_with_javascript_in_rails.html#rails-ujs-event-handlers
This is one possible solution:
$(document).on('ajax:success', '#reportform', event => { const [response, status, xhr] = event.detail;});
Turbolinks compatible
<script type="text/javascript"> $(document).on('ajax:success', 'a[data-remote].watching', function(e, data, status, xhr){ });</script>
