Google Maps Spiderfy open by default

Question

Looking to utlize the spiderfy which George MacKerron has developed. However I have one other requirement which is to load the map with all markers "spiderd" out by default. I can mimic this by using javascript to click on the markers, but there has to be another way by using the spiderfy code. Has anyone accomplished this?

https://github.com/jawj/OverlappingMarkerSpiderfier#overlapping-marker-spiderfier-for-google-maps-api-v3

var map = new google.maps.Map(document.getElementById("map-canvas"), options);
var iw = new google.maps.InfoWindow();
var oms = new OverlappingMarkerSpiderfier(map, {keepSpiderfied: true});

Answer 1

I came up with a solution that worked for me. After I've added all markers, I set a timeout to call a functiont to open each cluster and in the OMS js.

1. keepSpiderfied keeps all spideried markers open. It wasn't working for me so I altered the OMS js. If it works for you, you don't need to change this.

Find this:

(!e||!this.keepSpiderfied)&&this.unspiderfy();

Replace with this:

(!e||!this.keepSpiderfied);

2. function to call to open each cluster group:

   function openAllClusters() {
       var markers = oms.markersNearAnyOtherMarker();
   
       $.each(markers, function (i, marker) {
           google.maps.event.trigger(markers[i], 'click');
       });
   }
   

3. I set a timeout after I added my last marker (because it didn't work just calling the function immediately after):

   setTimeout(openAllClusters, 2000);
