Getting ID attribute when event is fired (subscriptions)

I have a subscription to calculate (Calculate String msg) something when user is writing on some divs (contenteditable).

subscriptions : CvModel -> Sub Msg
subscriptions _ = 
    onKeyUp (Decode.succeed Calculate) -- I need add the id element in message.

But, how I can get id attribute of the div where user is writing?

The decoder that you pass to onKeyUp is decoding the event object, so you can extract the id property of the target element (much like targetValue).

onKeyUp (Decode.at ["target", "id"] Decode.string |> Decode.map Calculate)

There's an example app at https://ellie-app.com/9MVn2Zsxptva1
