Hi,
I've just finished an project using Google Map APIs and have a way to zoom
in directly on a country.
I have a textfield to help user could input country which zoom to.
You can call this method when hit on button or onchange of textfield.
Hope you satisfied with it.
See my code below:
function zoomToLocation(address){
if(address){
var geo = new GClientGeocoder();
geo.getLocations(address, function (result){
// ===== Look for the bounding box of the first result =====
var N = result.Placemark[0].ExtendedData.LatLonBox.north;
var S = result.Placemark[0].ExtendedData.LatLonBox.south;
var E = result.Placemark[0].ExtendedData.LatLonBox.east;
var W = result.Placemark[0].ExtendedData.LatLonBox.west;
var bounds = new GLatLngBounds(new GLatLng(S,W), new
GLatLng(N,E));
// Choose a zoom level that fits
var zoom = map.getBoundsZoomLevel(bounds);
map.setCenter(bounds.getCenter(),zoom);
}
);
}
}
Phu.
