Javascript 基于标记的谷歌地图中心

我想根据动态加载的标记将谷歌地图居中。现在我正在地图上显示两个标记（请参见script.js文件）：

如何根据任何加载的标记将我的谷歌地图居中？我基本上想实现这样的目标：

这是我的密码：

如您链接的中所述，您需要在添加坐标时将坐标添加到

边界

对象，然后调用

fitBounds（bounds）

。看

尝试以下控制流：

let location1 = new google.maps.LatLng(lat, lng);
let location2 = new google.maps.LatLng(lat, lng);
let location3 = new google.maps.LatLng(lat, lng);

let marker = new google.maps.Marker({
    position: location1,
    map: map
});

marker = new google.maps.Marker({
    position: location2,
    map: map
});

marker = new google.maps.Marker({
  position: location3,
  map: map
});

let bounds = new google.maps.LatLngBounds();
bounds.extend(location1);
bounds.extend(location2);
bounds.extend(location3);
map.fitBounds(bounds);

如果您有一个很长的列表，那么您可能需要对数组或其他对象进行迭代

mapster.MAP_OPTIONS = {
  center: {
    lat: 37.791350,
    lng: -122.435883
  },
  zoom: 10,
  disableDefaultUI: false,
  scrollwheel: true,
  draggable: true,
  mapTypeId: google.maps.MapTypeId.ROADMAP,
  zoomControlOptions: {
    position: google.maps.ControlPosition.LEFT_BOTTOM,
    style: google.maps.ZoomControlStyle.DEFAULT
  },
  panControlOptions: {
    position: google.maps.ControlPosition.LEFT_BOTTOM
  },
  cluster: {
    options: {
      styles: [{

      }]
    }
  },
  geocoder: true
};

let location1 = new google.maps.LatLng(lat, lng);
let location2 = new google.maps.LatLng(lat, lng);
let location3 = new google.maps.LatLng(lat, lng);

let marker = new google.maps.Marker({
    position: location1,
    map: map
});

marker = new google.maps.Marker({
    position: location2,
    map: map
});

marker = new google.maps.Marker({
  position: location3,
  map: map
});

let bounds = new google.maps.LatLngBounds();
bounds.extend(location1);
bounds.extend(location2);
bounds.extend(location3);
map.fitBounds(bounds);
