When AJAX uploading data/files via input elements with ClojureScript, HTML5 returns FileList which is not really a list nor an array, hence can not be converted to Clojure by simply calling “js->clj“, although the usage is pretty similar to an array:
// uploadData is a form element // fileChooser is input element of type 'file' var file = document.forms['uploadData']['fileChooser'].files;
But as it is always in the Clojure world, there is a solution. This one is not trivial, but after spending almost 30 minutes, it surfaced under my finger tips:
(defn toArray [js-col] (-> (clj->js ) (.-slice) (.call js-col) (js->clj)))
Now in ClojureScript the “(toArray fileList)” will return a classic seq that can be loved and iterated.
