@larsvdd Try this one.

(function( $ ) {
'use-strict';

var throttleTimer = null;
var throttleDelay = 100;

$(function() {
var $win = $( window );
var $doc = $( document );

function ScrollHandler() {
  clearTimeout( throttleTimer );
  throttleTimer = setTimeout(function() {
    if ( $win.scrollTop() !== $doc.height() - $win.height() ) {
      return;
    }

    if ( FWP.settings.pager.page < FWP.settings.pager.total_pages ) {
      FWP.paged = parseInt( FWP.settings.pager.page ) + 1;
      FWP.is_load_more = true;
      FWP.soft_refresh = false;
      FWP.refresh();
    }
  }, throttleDelay );
}

wp.hooks.addFilter( 'facetwp/template_html', function( resp, params ) {
  if ( FWP.is_load_more ) {
    FWP.is_load_more = false;
    $( '.facetwp-template' ).append( params.html );
    return true;
  }

  return resp;
});

$doc.on( 'facetwp-loaded', function() {
  if ( ! FWP.loaded ) {
    $win.off( 'scroll', ScrollHandler ).on( 'scroll', ScrollHandler );
  }
});

});
})( jQuery );

The version with the $win and $doc vars works for me. How can I bind the facetwp-loading loader graphic to this? There is no indication more results are available.

it wasnt working for me. This code works:

by the way, a simple test if it works is by putting it in your functions.php like so:

add_action('wp_footer', 'add_faceet_wp_infinite_scroll');
function add_faceet_wp_infinite_scroll() {
if (is_admin() || is_checkout()) {
return;
}
?>
<script>

// TODO: script code comes here
</script>
<?php
}
