Select2 JS Loading remote data with Ajax

Answer 1

Your response is being returned as a Select2 3.x response, which is fine. We've provided the processResults method because of this (previously results) so you can modify the response on the client side.

In your case, your response includes the results key but your processResponse function is referencing a result key which does not exist. If you change it to something like

processResults: function (data, page) {
// parse the results into the format expected by Select2.
// since we are using custom formatting functions we do not need to
// alter the remote JSON data

  return {
    results: data.results,
    pagination: {
      more: data.more
    }
  };
},

Then things should start working. This also maps the existing more property on the response to the new pagination key that we migrated to in Select2 4.0.
