Overlapping Marker Spiderfier Marker Icon When There are Multiple Markers at Same Location

Question

Google Maps doesn\'t provide a way to break apart multiple markers that are at the same location. This can occur with a people or businesses at a multiple residency location suc

Answer 1

Here's how I got it to work. Where map is a Gmap instance and oms is an Overlapping Marker Spiderfier instance. We're also using Marker Clusterer on the initial zoom which buys us a break.

map.addListener('zoom_changed', function() {        

    map.addListenerOnce('idle', function() {

        // change spiderable markers to plus sign markers
        // we are lucky here in that initial map is completely clustered
        // for there is no init listener in oms :(
        // so we swap on the first zoom/idle
        // and subsequently any other zoom/idle

        var spidered = oms.markersNearAnyOtherMarker();

        for (var i = 0; i < spidered.length; i ++) {

            // this was set when we created the markers
            url = spidered[i].icon.url;

            // code to manipulate your spidered icon url
        };

    });

});


oms.addListener('unspiderfy', function(markers) {

    var spidered = markers;

    for (var i = 0; i < spidered.length; i ++) {

        url = spidered[i].icon.url;

        // change it back
    };
});


oms.addListener('click', function(marker) {

  // put the clicked-on marker on top
  // when oms un-spiders

  marker.zIndex=999;

  // set infowindow, panning etc.

});
