Check out this little bit of code:
(doseq [hid ["a" "b" "c"]]
(goog.dom.appendChild (goog.dom.$ "some-element-id")
(goog.dom.createDom "div" (.strobj {"id" hid}) (str "Test-"hid)))
(goog.events.listen (goog.dom.$ hid) goog.events.EventType.CLICK,
(fn [e] (js/alert hid))))
What I want it do to is add in a few div's that when clicked on simply
alert with the value their id value. That doesn't actually happen,
what happens is that they all alert with the "c" ie. the last value in
the list. This code, on the other-hand works:
(defn hidfn [hid]
(fn [e] (js/alert hid))
)
(doseq [hid ["a" "b" "c"]]
(goog.dom.appendChild (goog.dom.$ "the-receptor")
(goog.dom.createDom "div" (.strobj {"id" hid}) (str "Test-"hid)))
(goog.events.listen (goog.dom.$ hid) goog.events.EventType.CLICK,
(hidfn hid)))
Shouldn't the clojurescript compiler detect that the usage of "hid" in
the function in the first case requires the creation of an anonymous
function to close around that value? Why do I have to do it manually?
