在谷歌地图上显示/隐藏按钮点击

Question

我有谷歌地图标有一些城市。每个城市都有自己的团队。最初会向用户显示一个按钮，说明“选择城市”。

当用户点击标记并显示另一个带有城市名称的按钮时，如何隐藏它？

因此，当用户点击它时，将显示一个包含团队详细信息的新页面

HTML

<section ng-app="mapsApp" ng-controller="MapsCtrl">
  <div class="col-md-4">
  <button>choose city </button>
  <button ng-click="teamname(team)">
  Your team is {{teamname}}
  </button>
  </div>

  <div id="map" class="col-md-8"></div>
</section>
