Google Maps HeatmapLayer可点击的端点 [英] Google Maps HeatmapLayer clickable endpoints

问题描述

当用户达到缩放级别时，群集仅由1-4个LatLng点组成，我想使对象可单击以显示用于热图的数据源. 有关如何解决此问题的任何提示? 我可以将任何类型的EventListener连接到HeatmapLayer点吗?

When a user reaches a zoom level where the cluster only consist of 1-4 LatLng points I would like to make the object clickable to show source of the data used for the heatmap. Any tips on how to address this issue? Can I connect any type of EventListener to the HeatmapLayer points?

推荐答案

热图没有点击事件(基本上没有热图会监听的事件).

There is no click-event for a heatmap( basically there isn't any event a heatmap will listen to).

您可以做什么:使用markerClusterer.

What you can do: use a markerClusterer.

为所有点创建标记，因为markerImage会分配一个透明图像(大小应该为15x15)，然后将所需的点击事件应用于标记.

Create Markers for all points, as markerImage assign a a transparent image(a size of 15x15 should be fine) and apply the desired click-event to the marker.

将标记放入 markerClusterer 并将以下样式应用于群集器:

Push the markers into a markerClusterer and apply the following style to the clusterer:

  {
    url: 'path/to/transparentImage.png',
    height: 0,
    width: 0,
    textColor: 'transparent',
    textSize: 0
  }

结果:

只要标记聚集在一起，您将看不到任何东西.

as long as the markers are clustered, you'll not see anything.

当标记不再聚类时，您也不会看到任何内容(因为标记是透明的)，但是您可以单击透明标记，标记将对单击做出响应.

When a marker isn't clustered anymore, you'll also not see anything(because the marker is transparent), but you can click on the transparent marker, and the marker will respond to the click.
