javascript - 在传单绘制的编辑控件中分配多个功能组

Question

如何在编辑控件中分配多个功能组，

Assume we have two feature groups(It can be multiple),and we want to assign edit control to both groups.

这是组，

var attLayerGroup = new L.FeatureGroup();
var photoLayerGroup = new L.FeatureGroup();

这就是，我如何将控制分配给组，

    var drawControl = map.addControl(new L.Control.Draw({
    edit: {
        featureGroup: photoLayerGroup,attLayerGroup,
        poly: {
            allowIntersection: true
        }
    },
    draw: {
        polygon: {
            allowIntersection: false,
            showArea: true
        }

    }
}));

Is it right way to assigning Edit control to FeatureGroup ? If not,How can we do it?

Answer 1

如果您的 2 个初始特征组之间没有具体区别，则只需将每个图层的引用复制到新的父特征组中，并将后者用作 Leaflet.draw featureGroup 选项:

var fg = L.featureGroup();

photoLayerGroup.eachLayer(function (layer) {
  if (!layer instanceof L.LayerGroup) {
    fg.addLayer(layer);
  }
});

// Same for attLayerGroup.

new L.Control.Draw({
  edit: {
    featureGroup: fg
  }
});
