You have to reset the flag value inside the zoom_changed event
listener - not in your original function. Here's a rough example of
how I would do it:
var FindCorrectZoom = false;
function AddMarkers() {
for(var i = 0; i < 10; i++ {
AddMarker(i);
}
FindCorrectZoom = true;
map.fitBounds(MarkerBounds);
}
function processFitBoundsZoomChanged(currentZoom) {
//do something here
}
function zoom_changed_listener() {
if(FindCorrectZoom) {
FindCorrectZoom = false;
processFitBoundsZoomChanged(this.getZoom());
}
}
google.maps.event.addListener(map, 'zoom_changed',
zoom_changed_listener);
I used this technique in my code to limit the maximum zoom level a
call to fitBounds could use.
