Hi,
I have several functions that do an async request to the server. There are
constraints for this functions.
1. Only send an request if some value is not empty
2. Disable and enable some button before and after the request.
A function might look like this:
(defn add-group []
(let [g-name (h/get-value "add-group-input")
;repetitive get element
clicked-button (h/get-elem "add-group-btn")]
;repetitive only send when not empty
(when (not-empty g-name)
(go (let [[ok uuid] (<! (h/post-async "/admin/group/add" {:name g-name}
clicked-button))]
(if ok (do (swap! app-state update-in [:groups] conj {:name g-name
:uuid uuid})
(set-user-selection-hidden-state (:groups @app-state))
(h/show-success-message "notification-div" "Group Added"))
(h/show-error-message "notification-div"))
;repetitive remove disbled attribute
(.removeAttribute clicked-button "disabled"))))))
How would I put this repeating code into a function? Or would I need to write a
macro for this kind of repetition?
Best Regards,
Sven
