Google 地图 - 无法读取未定义的属性（读取“球形”）

Question

我想在搜索后滚动到壁橱标记。Console.log 显示 pin[i] = (50.296322, 9.112082) 和事件 (50.937531, 6.9602786)。我尝试了很多，但总是得到：无法读取未定义的属性（读取“球形”）

function geocodeAddress(geocoder, resultsMap){
var address = document.getElementById('address').value;
geocoder.geocode({'address': address}, function(results, status){
    if (status === 'OK') { 
        function find_closest_marker(event){
            var distances = [];
            var closest = -1;
            for(i = 0; i < pins.length; i++){
                var d = google.maps.geometry.spherical.computeDistanceBetween(pins[i].position, event);
                distances[i] = d;
                if (closest == -1 || d < distances[closest]){
                    closest = i;
                }
            }
            resultsMap.setCenter(pins[closest].position);
        } 
        find_closest_marker(results[0].geometry.location);          
    } else {
        alert('Geocode was not successful for the following reason: ' + status);
    }
});

}
