Code

function leaflet_geojson_add_bbox_strategy($source_info) {

  // Add bounding box javascript.
  drupal_add_js(drupal_get_path('module', 'leaflet_geojson') . '/leaflet.bbox.js', array(
    'weight' => 5,
  ));

  // Add custom settings.
  // The JS now expects an array even if there's only one layer, so be sure
  // the single layer is nested properly (the keyname is not important).
  // @TODO fix this.
  if (isset($settings['view_display'])) {

    // Create the base settings to be compatible with the new Views GeoJSON.
    // This will happen when the map block is built by leaflet_geojson_bean.
    $settings = $source_info;

    // Then add a copy in leaflet_1 for bean.
    $settings['leaflet_1'] = $source_info;
  }
  else {

    // This will happen when the block is placed by the ctools (panels) plugin.
    $settings = $source_info;
  }
  drupal_add_js(array(
    'leafletBBox' => $settings,
  ), 'setting');
