从数组添加动态叠加层

Question

I am trying to add new layers to the map using the leaflet. First I create the layers by a form then I put the elements related to their relationship. The problem is that to add a new layer to the overlayers object is using static code, and I wanted to use all the layers that I am creating and are downloaded from the database. Does anyone have an idea?

var tipo1 = L.layerGroup();
var tipo2 = L.layerGroup();

var overlayers = {
  "Tipo 1": tipo1,
  "Tipo 2": tipo2
};  

This example works. This is how it should be used. But in my case, instead of using tipo1 and tipo2 ... I would have one or more types coming from a database, and wanted to add to overlayers.

You don't post much code, but assuming you're using a Layers control, you can add layers dynamically - eg

var myLayersControl = L.control.layers(null, null).addTo(map);
var myNewLayer = L.layerGroup();
myLayersControl.addOverlay(myNewLayer, "Description");
