Note the following code that works:
(defn ^:export displayPlain [id]
(let [h (.getElementById window/document id)
txt (aget h "innerText")]
(window/alert (str "plain " txt))
(aset h "innerText" "here I am!")))
Here, javascript object "h" is treated as array, and I was able to get and
set its value (since it is mutable).
Note that the following code doesn't work, since h is not a map, and thus we
can't access its properties neither as keywords nor as names.
(defn ^:export displayPlain2 [id]
(let [h (.getElementById window/document id)
;; txt (get h "innerText")
txt (:innerText h)]
(window/alert (str "plain " txt))))
This makes dealing with js objects a bit mor verbose than clojure maps. It
would be good if Clojure maps and JS object would be interchangeable from
ClojureScript code.
Would it make sense to open a bug/feature for this?
I know that this is doable using closure library, but it would be nice if it
could be easily doable using plain objects.
(defn ^:export display [id]
(let [h (dom/getElement id)
txt (dom/getTextContent h)]
(window/alert (str "gdom " txt))))
