Get layer name by click on features OpenLayers3

Question

I want to add selec interactions to my OL3 map. Adding two different select interactions like this is not working. Only the second one works. Like this:

 var select = new ol.interaction.Select({
 layers: [clusters]
 });
select.getFeatures().on('add', function (e) {alert("orange")});
 map.addInteraction(select);
 var select2 = new ol.interaction.Select({
 layers: [clustersSarv]
 });
select2.getFeatures().on('add', function (e) {alert("blue")});
 map.addInteraction(select2);

Now I am trying to do something like this, but I am unable to get layer on which is clicked, to define different actions for different layers.

var select = new ol.interaction.Select({
 layers: [clusters,clusters2]
 });
select.getFeatures().on('add', function (e) {
 console.log(e.element);
// if layer is clusters alert("orange")});
 map.addInteraction(select);

Any suggestions? Main question is how to get a layer name by clicking on layer's features.

Answer 1

To answer your question about grabbing the layer from a clicked feature, you can do the following:

map.on(ol.MapBrowserEvent.EventType.SINGLECLICK, function (e) {
 map.forEachFeatureAtPixel(e.pixel, function (feature, layer) {
 ...
 });
}
