Get layer name in layerList widget

Question

Hey,

i just tried to add some actions to my layerlist widget. (increase/decrease opacity, zoom to extent)

In this example they called a special layer by name but i want to use this actions on each layer in my map.

Isn't there an easy way to define the selected Layer in the layerList widget?

I didn't find anything easy like "var layer = layerlist.selectedLayer"

Thank you

I was looking to do the same thing, but your excerpt didnt work for me. Would you be able to provide the exact syntax you used?

Thanks

Thanks again for your fast reply @ReneRubalcava

The Solution that works for me is;

layerList.on("trigger-action", (event) => {
   var activeLayer = event.item.layer.name;
   console.log(activeLayer);
});

Defining the 'name" in the layer definition...

selectedItems is a Collection, so you can use ".on()" to listen for events, like this sample.
