使用谷歌api获取多边形内的商店

Question

我想在绘制的多边形内找到商店，但却无法找到任何解决方案。我在地图中有多个多边形，需要显示每个多边形的特定商店类型的数量。

geocoder.geocode({
                    'address': placeName
                }, function (results, status) {
                    if (status == google.maps.GeocoderStatus.OK) {
                        var geometry = results[0].geometry,
                            places = new google.maps.places.PlacesService(bgMap);
                        places.nearbySearch({
                            bounds: bounds,
                            types: [
                                'establishment'
                            ]
                        }, function (results, status) {
                            if (status == google.maps.places.PlacesServiceStatus.OK) {
                                for (var i = 0; i < results.length; i++) {
                                    markers.push(new google.maps.Marker({
                                        position: results[i].geometry.location,
                                        map: bgMap
                                    }));
                                }
                            }
                        });
                        //console.log(markers);
                    } else {
                        return $('#map').html('could not locate you');
                    }
                });

bounds是坐标列表;
