问题 I have use Google Maps API v3 to create polylines representing trails on numerous maps. There are multiple polylines on each map. When zoomed out I would like the polylines to have a lighter strokeWeight, but heavier when zoomed in. I tried adding a zoom change listener and have it change a variable value for the strokeWeight, but it doesn't appear to work. I need Google to somehow redo the google.maps.Polyline({...}). Also, I need to do this globally, as I said, I have many polylines on each

问题 ...depending on where I put the line var mc = new markerclusterer(map); If it goes where the examples seem to suggest - right after "var map" is introduced - all the markers disappear (example running here).
