I found a piece of code for dynamic creation of HTML5 elements and adding a reactive contents to it.
let open Js_of_ocaml_tyxml.Tyxml_js in let input_area = To_dom.of_textarea @@ R.Html5.( textarea ~a:[ a_id (Xml.W.return "input_area") ] @@ React.S.map (fun n -> let n = n mod List.length examples in log "Got a signal with index %d" n; let _, spec = List.nth examples n in txt (Xml.W.return spec)) (fst reactive_stuff123))
Also I know a piece of code to add a handler to already existing element using pure Js_of_ocaml:
let combo = Dom_html.getElementById_coerce "demos" Dom_html.CoerceTo.select |> Option.get in combo##.onchange := Dom_html.handler (fun _ -> (* stuff *) Js._true);
Question: How could I use a reactive value as contents of already created HTML element? In other words, how should I combine reactive stuff with
P.S. My reactive textarea looks verbose, and it doesn’t react on reactive events when I manually change the contents of text area, but it’s probably a topic for another question.
