Jair,

I am not an expert...if this doesn't work, I hope someelse helps you.
I am sure there are other ways to achive this.

once said that,

When creating your layers you need to add an "id" attribute. See the example
bellow.
Then, use get the onclic mouse event, and


earthQuakeLayer = new ol.layer.Vector({
  source: new ol.source.Vector({
    ....
  }),
  id:'yourlayerid' 
});

Then , when listening the clic event, you need to use something similar to
this.

    
map.on('click', function (e) {
  map.forEachFeatureAtPixel(e.pixel, function (feature, layer) {
  console.debug(layer.get('id'));
  });
}

Hello,

 

In a multi-layer map how to determine the clicked layer name when the user
click on the map?

 

Thanks,

 

JJ.
