Hello

For do this simple operation you need implement next function:

function  address_func(addresses, callback) {
        var coords = [];
        for(var i = 0; i < addresses.length; i++) {
            currAddress = addresses[i];
            var geocoder = new google.maps.Geocoder();
            if (geocoder) {
                geocoder.geocode({'address':currAddress}, function (results, status) {
                    if (status == google.maps.GeocoderStatus.OK) {
                        coords.push(results[0].geometry.location);
                        if(coords.length == addresses.length) {
                            if( typeof callback == 'function' ) {
                                callback(coords);
                            }
                        }
                    }
                    else {
                        throw('No results found: ' + status);
                    }
                });
            }
       }
    }

And use this function as:

var address_array = ["514 Broadway, Brooklyn, New York, NY, United States"]
address_func([select_val], function(results){
for(marker in results)
{
   var marker_lat_lng = new google.maps.LatLng(results[marker].lat(), results[marker].lng());
   var marker = new google.maps.Marker({
					 position: marker_lat_lng,
					 map: map,
					});
}
});
