Google地图，地理编码器，JavaScript：找不到地址时，将标记放在中间

Question

I'm doing a page with geocode, it's working well, but always come in the array of addresses places that it's not catalogated in google maps. Unfortunatly, the geocoder, instead of not doing nothing, put the marker of the not found address in the center of the map.

There's some code to make the geocoder not put this not found marker?

(I'm brazilian, my english it's bad, sorry =))

function addMarker(position) {          
        var geocoder;
        geocoder = new google.maps.Geocoder();  
        geocoder.geocode({'address': address[position]}, function(results, status) {
            if (status == google.maps.GeocoderStatus.OK) {              
                places[position] = results[0].geometry.location;
                var marker = new google.maps.Marker({
                    position: places[position],
                    map: mapa,
                    icon: icone, 
                    title: ('OS: ' + arOS[position] + ' - ' + arEndereco[position]), 
                    url: 'OSDETALHES.asp?txtCodigoOS=' + arOS[position]
                });         
                google.maps.event.addListener(marker, 'click', function() {
                window.open(this.url, '_blank');
                });
            }
            else
            {
                if (status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT)
                {
                    setTimeout(function() { addMarker(position); }, (timeout * 3));
                }
            }
            address_position++;
            if (address_position < address.length)
            {
                setTimeout(function() { addMarker(address_position); }, (timeout));
            }
        });
    }
}

Answer 1

You should be looking at Geocoding Results to determine how well Geocoding worked.

geometry contains the following information:

location_type stores additional data about the specified location. The following values are currently supported:

• google.maps.GeocoderLocationType.ROOFTOP indicates that the returned result reflects a precise geocode.
• google.maps.GeocoderLocationType.RANGE_INTERPOLATED indicates that the returned result reflects an approximation (usually on a road) interpolated between two precise points (such as intersections). Interpolated results are generally returned when rooftop geocodes are unavailable for a street address.
• google.maps.GeocoderLocationType.GEOMETRIC_CENTER indicates that the returned result is the geometric center of a result such as a polyline (for example, a street) or polygon (region).
• google.maps.GeocoderLocationType.APPROXIMATE indicates that the returned result is approximate.

Updated Per Comments

I have not used this, but something very close to this should work:

if (results[0].geometry.location.location_type != 'ROOFTOP')
{
  // not an exact match
}

Answer 2

RANGE_INTERPOLATED, apparently, solved my problem:

if (results[0].geometry.location_type == google.maps.GeocoderLocationType.RANGE_INTERPOLATED){
