如何使用图层应用传单标记簇

Question

我正在尝试应用 Leaflet.MarkerCluster.LayerSupport。但我不知道如何使用它 :( 我已经阅读了关于 but 的文档并且我尝试了很多次但它没有用。

这是我的代码

    <script src="leaflet.markercluster.layersupport-src.js"></script>


    <script>        

        var NemachIcons =L.Icon.extend({
            options:{
                shadowUrl:'',
                iconSize:   [50,55],
                iconAnchor: [45,45],
                popupAnchor:[-3,-76]
            }
        });

        var tiloIcon = new NemachIcons({iconUrl:'http://www.iconshock.com/img_jpg/SIGMA/general/jpg/256/pyramid_icon.jpg'}),
            puebloIcon = new NemachIcons({iconUrl:'http://icons.iconseeker.com/png/fullsize/gant/pointless-bw-circle-i-use-it-iex.png'}),
            gasIcon =new NemachIcons({iconUrl:'https://cdn2.iconfinder.com/data/icons/function_icon_set/circle_green.png'});


        L.icon =function (options) {
            return new L.Icon(options);
        };


        var sitios = new L. LayerGroup();

        L.marker([20.683, -88.568], {icon: tiloIcon}).bindPopup('1').addTo(sitios),
        L.marker([21.204547, -89.269466], {icon: tiloIcon}).bindPopup('2').addTo(sitios),
        L.marker([20.332362, -89.647899], {icon: tiloIcon}).bindPopup('3').addTo(sitios),

        L.marker([21.151196, -87.958143], {icon: tiloIcon}).bindPopup('5').addTo(sitios);


        var pueblo = new L.LayerGroup();

        L.marker([20.9330, -89.0178], {icon: puebloIcon}).bindPopup('6').addTo(pueblo),
        L.marker([20.6909, -88.2015], {icon: puebloIcon}).bindPopup('7').addTo(pueblo);

        var gas = new L.LayerGroup();
        L.marker([20.973907, -89.578931], {icon: gasIcon}).bindPopup('8').addTo(gas);


        var mbAttr = ' ' +
                '' +
                '',
            mbUrl = 'https://api.tiles.mapbox.com/v4/{id}/{z}/{x}/{y}.png?access_token=pk.eyJ1IjoibWFwYm94IiwiYSI6ImNpandmbXliNDBjZWd2M2x6bDk3c2ZtOTkifQ._QA7i5Mpkd_m30IGElHziw';

        var grayscale   = L.tileLayer(mbUrl, {id: 'mapbox.light', attribution: mbAttr}),
            streets  = L.tileLayer(mbUrl, {id: 'mapbox.streets',   attribution: mbAttr});

        var map = L.map('map', {
            center: [20.794527, -88.760612],
            zoom: 8,
            layers: [grayscale, sitios]
        });

        var baseLayers = {

            //"Grayscale": grayscale,
            //"Streets": streets

        };

        var overlays = {
            "Pirámide": sitios,
            "Poblado": pueblo,
            "Servicio": gas
        };

        L.control.layers(baseLayers, overlays).addTo(map);
    </script>

非常感谢您的所有回答

Answer 1

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。

在图层支持的情况下，您创建一个带有图层支持的标记集群组：

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

然后你 "check in" 子组，以便他们知道他们必须进入那个集群组而不是直接到地图，当他们通过图层控制选择时：

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

注意：您应该下载 JavaScript 文件 leaflet.markercluster.layersupport-src.js，如果尚未完成，请将其放在您的 HTML 页面旁边, 以便它可以在本地引用它。

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.
