How to remove layer from a LayerGroup?

[Michal Zimmermann]

Hi,

I have LayerGroup which is dynamically filled by user as he/she clicks on the map. I would like to allow him/her to delete the layer created, but haven't found out how yet. There is a removeLayer() method on LayerGroup, but what should I pass as the parameter? An ID, object? I need to identify which layer shall be removed, but I have no idea how to do that.

Each layer is assigned a leaflet ID, so you could iterate over the layers in the group using the eachLayer method and look for the ID to remove. Wrap everything in a function that you can call when you want to remove a layer by it's ID. Something like this:

var mylayergroup = new L.LayerGroup();

function removeMe(id) {

mylayergroup.eachLayer(function (layer) {

if (layer._leaflet_id === id){

mylayergroup.removeLayer(layer)

}

});

}

When you want to remove the layer with a leaflet_id of 50, you would just call removeMe(50).
