11   * Handles "facets_filter" event and triggers "facets_filtering".
12   *
13   * The facets module will listend and trigger defined events on elements with
14   * class: "js-facets-widget".
15   *
16   * Events are doing following:
17   * "facets_filter" - widget should trigger this event. The facets module will
18   *   handle it accordingly in case of AJAX and Non-AJAX views.
19   * "facets_filtering" - The facets module will trigger this event before
20   *   filter is executed.
21   *
22   * This is an example how to trigger "facets_filter" event for your widget:
23   *   $(once('my-custom-widget-on-change', '.my-custom-widget.js-facets-widget'))
24   *     .on('change', function () {
25   *       // In this example $(this).val() will provide needed URL.
26   *       $(this).trigger('facets_filter', [ $(this).val() ]);
27   *     });
28   *
29   * The facets module will trigger "facets_filtering" before filter is
30   * executed. Widgets can listen on "facets_filtering" event and react before
31   * filter is executed. Most common use case is to disable widget. When you
32   * disable widget, a user will not be able to trigger new "facets_filter"
33   * event before initial filter request is finished.
34   *
35   * This is an example how to handle "facets_filtering":
36   *   $(once('my-custom-widget-on-facets-filtering', '.my-custom-widget.js-facets-widget'))
37   *     .on('facets_filtering.my_widget_module', function () {
38   *       // Let's say, that widget can be simply disabled (fe. select).
39   *       $(this).prop('disabled', true);
40   *     });
41   *
42   * You should namespace events for your module widgets. With namespaced events
43   * you have better control on your handlers and if it's needed, you can easier
44   * register/deregister them.
