no , looks optimization related which we mostly haven’t gotten to yet

good q, we will need to think about this

possibly electric-dom will need to be changed, there have been some chats internally about doing batched dom updates which is related

differential electric is first

why do you think it doesn't work? have you tried printing the value of username on click?

(def usernameInput (.getElementById js/document "username")) executes on JS file load (when the page loads) At the time it runs, the #username HTML is not mounted yet

I giving an invalid number input i.e. "12" it must be a minimum of 3 characters. That doesn't show me an error as in HTML

well, geoffrey gave you the answer 😛 but generally you can narrow down what the problem must be by printing stuff out that you think should be run

Also, while Electric compiles down to JS, their evaluation model are different (imperative vs reactive). You cannot directly translate idiomatic JS into idiomatic Electric. Let me get back to you with an idiomatic Electric code snippet

electric creates the elements dynamically when the js is run, while the browser will read the html first and create those elements before the js is run

@U2DART3HA Thanks, I want to learn JavaScript usage in electric I think i will need it always 🙂

Notes: • + in clojure only does addition. Use str to concatenate strings • < , >, <=, >= can take more than two args. Useful to check ranges: “x is between 3 and 12 included” : (<= 3 x 12) If you want to call addEventListener manually, you can do so on dom/node:

(dom/button ; in this block, the current DOM node is bound to `dom/node`
  (dom/text "Click me")
  (.addEventListener dom/node "click" handle-click))

(defn handle-click [^js event]
  (js/alert "Button was clicked")) 

Thanks! Starting study on it.

That is very valueable help for me. 🙂

I would consider doing all imperative js-style code in ordinary clojurescript until you have a reason not to. Just use defn instead of e/defn

I guess you were already doing this, maybe this comment isn't helpful
