window.addEventListener( 'DOMContentLoaded', function() {

		var $map = $( '.jet-map-listing' );

		if ( ! $map.length ) {
			return;
		}

		$map.on( 'jet-filter-custom-content-render', function( event, response ) {

			if ( ! response.markers.length ) {
				var mapInstance = $( event.target ).data( 'mapInstance' );
				
				// Using the mapInstance can now use methods from the map api
				// Ex: https://developers.google.com/earth-engine/apidocs/map-setzoom
				mapInstance.setZoom( 5 );
