Rossko,
Thanks a lot for your response. I just start to learn Google Map Api. Do
you mean I just need the following code in listener?
Thanks a lot.
google.maps.event.addListener(map, 'idle', function() {
number++;
if (number%2==0) //decide which kml file shoulded be used
ctaLayer = new google.maps.KmlLayer(file1);
else
ctaLayer = new google.maps.KmlLayer(file2);
ctaLayer.set('preserveViewport', true);
ctaLayer.setMap(map);
});
