Google地图：点击标记的自动中心地图

Question

我需要在我正在制作的地图上提供一些帮助。地图不是特别复杂，因为我是初学者，我有一堆标记（一旦完成后会有更多），可以在点击标记时打开信息窗口，或者在HTML上选择相应的下拉菜单项目时打开页面的一侧。

我想做的并且无法自己找到的是当infowindow打开时自动居中地图上的标记（单击或在HTML菜单中选择）。我想有一些函数可以分配给click或infowindow开启事件，但无法确定实现它的方式和方法。

我的代码：

function initialize() {

      var CarteStyles = [
        {
          featureType: "all",
          stylers: [
            { saturation: -50 }
          ]
        },
        {
        elementType: "labels",
        stylers: [
          { visibility: "off" }
        ]
      },
        {
            featureType: "road",
            stylers: [
              { visibility: "simplified" },
              { saturation: -90 }
            ]
        },
        {
        featureType: "road.local",
        "stylers": [
          { "color": "#dbdbd4" }
        ]
      },
    {
          featureType: "road",
          elementType: "labels",
          stylers: [
            { visibility: "off"}
          ]
        },
        {
            featureType: "poi",
            stylers: [
              { visibility: "off" }
            ]
        },
        {
          featureType: "poi.park",
          stylers: [
            { visibility: "on" }
          ]
        },
        {
          featureType: "poi.park",
          elementType: "labels",
          stylers: [
            { visibility: "off"}
          ]
        }
      ];

Answer 1

稍微好一点（视觉上）是使用panTo而不是setCenter，如下所示：

google.maps.event.addListener(RdrMarker, 'click', function() {
   map.panTo(RdrMarker.getPosition());
   infowindow.setContent(contentStringRdr);
   infowindow.open(map,RdrMarker);
});

这会重新集中，但它会动画而不是跳跃。

Answer 2

您已在标记上使用点击处理程序，因此您只需添加一行以将地图置于标记的中心位置：

google.maps.event.addListener(RdrMarker, 'click', function() {
   map.setCenter(RdrMarker.getPosition());
   infowindow.setContent(contentStringRdr);
   infowindow.open(map,RdrMarker);
});

Answer 3

可以使用以下代码自动将地图置于标记点击中心：

google.maps.event.addListener(marker, 'click', function() {
     map.setCenter(marker.getPosition());   
});
