问题描述

我正在尝试应用 Leaflet.MarkerCluster.LayerSupport.但我不知道如何使用它 :( 我已经阅读了有关但我尝试了很多次但它不起作用的文档.

I´m trying to apply the Leaflet.MarkerCluster.LayerSupport. But I don´t know how to use it :( I´ve already read the documentation about but and I tried many times but it doesen´t work.

这是我的代码

我会感谢你所有的回答

推荐答案

与 Leaflet.markercluster 一样，您必须创建一个标记集群组，您的子组将进入该组.

Like for Leaflet.markercluster, you have to create a Marker Cluster Group where your sub-groups will go into.

在层支持的情况下，您创建一个具有层支持的标记集群组:

In the case of Layer Support, you create a Marker Cluster Group with Layer Support instead:

var mcg = L.markerClusterGroup.layerSupport().addTo(map);

然后您签入"子组，以便他们知道在通过图层控件选择它们时必须进入该聚类组而不是直接进入地图:

Then you "check in" the sub-groups, so that they know they have to go into that clustering group rather than directly to the map, when they are selected through the Layers Control:

mcg.checkIn([
    sitios,
    pueblo,
    gas
]);

注意:您应该下载 JavaScript 文件 leaflet.markercluster.layersupport-src.js(如果尚未下载)，并将其放在您的 HTML 页面旁边，这样它可以在本地引用它.

Note: you should download the JavaScript file leaflet.markercluster.layersupport-src.js, if not already done, and place it next to your HTML page, so that it can refer to it locally.

注意 2:如果您的使用只需要集群与 L.Control.Layers 的兼容性，您可能会对这个更简单的插件感兴趣:Leaflet.FeatureGroup.SubGroup.

Note 2: if your usage requires only compatibility of clustering with L.Control.Layers, you might be interested in this more simple plugin: Leaflet.FeatureGroup.SubGroup.
