Why are you doing this?
if (new_markers.length > 1 ) {
var bounds = new GLatLngBounds(new_markers[0].getLatLng(), new_markers
[1].getLatLng());
}
for (var i=2; i < new_markers.length; i++) {
bounds.extend(new_markers[i].getLatLng())
}
The first part gets the order wrong and makes the bounds cover the
whole world. If you combine them into a single loop instead, you not
only make your life easier, but it works:
var bounds = new GLatLngBounds();
for (var i=0; i < new_markers.length; i++) {
bounds.extend(new_markers[i].getLatLng())
}
and you can make your code even more efficient by adding the markers
at the same time rather than looping through the array a second time
to add them...
