HI,

I am trying to add marker clustering in to acf google maps js code, but I fail.
Nothing seems to work, can someone check my code please ?

I am using markerCluster.js, which is added and loaded.

(function($) {
/*
*  new_map
*/

function new_map( $el ) {
	
	// var
	var $markers = $el.find('.marker');
	
	// vars
	var args = {
		zoom		: 12,
		center		: new google.maps.LatLng(52.279776, 19.343746),
		mapTypeId	: google.maps.MapTypeId.ROADMAP,
		scrollwheel: true,
		zoomControlOptions: {
			style: google.maps.ZoomControlStyle.SMALL,
			position: google.maps.ControlPosition.RIGHT_CENTER
		},
		styles: [{"elementType":"geometry","stylers":[{"color":"#bb12f2"}]},{"elementType":"labels","stylers":[{"color":"#ffffff"},{"visibility":"on"}]},{"elementType":"labels.icon","stylers":[{"visibility":"off"}]},{"elementType":"labels.text.fill","stylers":[{"lightness":20},{"gamma":0.01}]},{"elementType":"labels.text.stroke","stylers":[{"saturation":-31},{"lightness":-33},{"gamma":0.8},{"weight":2}]},{"featureType":"landscape","elementType":"geometry","stylers":[{"saturation":30},{"lightness":30}]},{"featureType":"landscape","elementType":"geometry.fill","stylers":[{"visibility":"on"}]},{"featureType":"poi","elementType":"geometry","stylers":[{"saturation":20}]},{"featureType":"poi.park","elementType":"geometry","stylers":[{"saturation":-20},{"lightness":20}]},{"featureType":"road","elementType":"geometry","stylers":[{"saturation":-30},{"lightness":10}]},{"featureType":"road","elementType":"geometry.stroke","stylers":[{"saturation":25},{"lightness":25}]},{"featureType":"water","stylers":[{"lightness":-20}]}]
		
	};
	
	// create map	        	
	var map = new google.maps.Map( $el[0], args);
	
	// add a markers reference
	map.markers = [];
	
	// add markers
	$markers.each(function(){
    	add_marker( $(this), map );	
	});
	
	// center map
	center_map( map );

	// return
	return map;	
}

/*
*  add_marker
*/

function add_marker( $marker, map ) {

	// var
	var latlng = new google.maps.LatLng( $marker.attr('data-lat'), $marker.attr('data-lng') );

	// create marker
	var marker = new google.maps.Marker({
		position	: latlng,
		map			: map,
		icon: "http://gonzo.mastafu2.pro-linuxpl.com/wp-content/themes/customTpl/img/googleMarker.png"
	});
	
	// add to array
	map.markers.push( marker );

	// if marker contains HTML, add it to an infoWindow
	if( $marker.html() )
	{
		// create info window
		var infowindow = new google.maps.InfoWindow({
			content		: $marker.html()
		});

		// show info window when marker is clicked
		google.maps.event.addListener(marker, 'click', function() {

			infowindow.open( map, marker );

		});
	}
}

/*
*  center_map
*/

function center_map( map ) {

	// vars
	var bounds = new google.maps.LatLngBounds();

	// loop through all markers and create bounds
	$.each( map.markers, function( i, marker ){

		var latlng = new google.maps.LatLng( marker.position.lat(), marker.position.lng() );

		bounds.extend( latlng );

	});

	// only 1 marker?
	if( map.markers.length == 1 )
	{
		// set center of map
	    map.setCenter( bounds.getCenter() );
	    map.setZoom( 16 );
	}
	else
	{
		// fit to bounds
		map.fitBounds( bounds );
	}
}

function markerCluster( markers, map ) {
	var markerCluster = new MarkerClusterer(map, markers, {imagePath: 'https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m'});
	console.log( markers );
}
/*
* Render when ready
*/
// global var
var map = null;

$(document).ready(function(){

	$('.acf-map').each(function(){

		// create map
		map = new_map( $(this) );

	});

});
})(jQuery);

Hi @mastafu

I think that’s because you’ve set the function, but never execute it. Could you please try it like this:

// add markers
$markers.each(function(){
    add_marker( $(this), map );	
});

// center map
center_map( map );

// add marker cluster
markerCluster( map.markers, map )

// return
return map;

Because this issue is more related to Google Map, kindly get in touch with Google Maps community for further support.

Thanks 🙂

Best example of not to code very late 🙂

I tried this, but console gave me still “MarkerClusterer is not defined” and not work unfortunately. Did i something wrong? Thanks

Here is my code

	// create map	        	
	var map = new google.maps.Map( $el[0], args);
