我有一个SPA，它在地图上显示按地区，州/省和最终城市过滤的地图。我在我的位置有Lat / Lng，我将它传递给地图标记并在每个选择列表选择中过滤它。我正在讨论让地图集中在每个区域的问题，因为它随后被过滤掉了。
有没有办法在使用标记显示标记时重新定位，或者为此我需要重新编写代码以处理在JS中显示标记而不是标记？

看起来像添加zoom-to-include-markers =＆＃34; true＆＃34;到地图元素实现了这一点。
<div map-lazy-load="http://maps.google.com/maps/api/js">
<map zoom="1" scrollwheel="false" zoom-to-include-markers="auto">
<span ng-repeat="site in (dataObject | ForMap : {region:selectRegion, state:selectState, city:selectCity}) track by $index" id="{{data.Id}}">
<marker position="[{{site.Latitude}},{{site.Longitude}}]"></marker>
</span>
</map>
</div>
