Toggle layers on/off using Web Map ID instead of Dynamic Map Service

Question

I'm fairly new to the JS API and I'm working on an extension of StoryMaps app in ArcGIS.

I want to create a toggle on/off for webmaps and I was following up on the code provided by Kelly to a discussion thread.

My webpage where the app works for now is: Create a Web Map.

If you try to toggle layers on/off then, it doesn't work. Can anyone help me?

Aravind Sivasailam, I added "esri/layers/FeatureLayer" to your script, found:FeatureLayer | API Reference Try this: Create a Web Map

EDIT: Never mind You see to have found the solution.

Hello Ken,

I solved the issue. It was a mistake on my part to not publish the layers I was using inside the web map. Once, I used both the published layers inside, it was very easy to be able to just modify the app.

The app works: Create a Web Map

Hello Ken,

Thank you. I solved one part of the problem with the feature layer "883 stops" showing different IDs. This was because I erroneously published the point feature layer as points, lines, text and area layer. That's why there are 4 IDs.

I changed the layer to point alone and saved the map. Now, when I run the app again, I am able to toggle on/off the "883 stops" layer, but not the "crime by city" layer.
