Rails unobtrusive javascript (UJS) ajax:before append data params

Looking into this, it is actually possible to do, but you do not use the event, you modify the form itself (using $(this)).

So something like this could work:

$(document).on("ajax:before",".form-example", function() {
  var form = $(this);
  form.append($('<input />',{name: 'hidden_values',value: $(":hidden").serialize()}));
});

And you should be able to access the data in your rails action using params[:hidden_values].
