Try this:
var marker = null;
function codeAddress(info) {
var address = info;
infowindow = new google.maps.InfoWindow({
content: address
});
if (geocoder) {
geocoder.geocode( { 'address': address}, function(results,
status)
{
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
if(marker)
marker.setPosition(results[0].geometry.location);
else
marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
infowindow.open(map,marker);
} else {
alert("Geocode was not successful for the following reason:
" + status);
}
});
}
}
