leaflet - Leaflet.draw在draw:edited事件上检索图层类型

Question

我正在使用https://github.com/Leaflet/Leaflet.draw插件，并且试图检索已编辑图层的图层类型。

在draw:created事件中，我有layer和layerType，但是在draw:edited(保存所有编辑时触发)上，我得到了已编辑图层的列表。

draw:created 事件

map.on('draw:created', function (e) {
    var type = e.layerType,
        layer = e.layer;

    if (type === 'marker') {
        // Do marker specific actions
    }

    // Do whatever else you need to. (save to db, add to map etc)
    map.addLayer(layer);
});

draw:edited 事件

map.on('draw:edited', function (e) {
    var layers = e.layers;
    layers.eachLayer(function (layer) {
        //do stuff, but I can't check which type I'm working with
        // the layer parameter doesn't mention its type
    });
});

您可以使用instanceof (docs here)。

map.on('draw:edited', function (e) {
    var layers = e.layers;
    layers.eachLayer(function (layer) {
        if (layer instanceof L.Marker){
            //Do marker specific actions here
        }
    });
});
