Google Maps Marker丛集

Question

Hi I am trying to add clustering to my google map. Its been about eight years since I've actually programmed anything so I've reverted to modifying another website due to my lack of knowledge. I have added the maerkerclusterer.js script to my page, but I have not idea where to parse

var markerCluster = new MarkerClusterer(map, markers);

though the marker array. A demo of my code can be found below:

Google Map

Answer 1

Line 115 should be :

var len = guests.length;
var markerArray = [];

Than, lines 141-142 to:

var marker = google.maps.Marker(map, guests[i]);
markerArray.push(marker );

      } 
var markerCluster = new MarkerClusterer(map, markerArray);

This should get it to work.

The point of the chnge is to sen the MarkerClusterer an array that contains only the markers, nothing else as the core code is other wise confused and throwing errors.
