This is due to c5eeeaf and happens if GHCJS_BROWSER is defined. (I'm not really sure why nobody has reported this problem before. It could be something else about the way we're building our app, but I'm not really sure what that would be.)

Should the line be changed as follows?

-  if ( h$isNode ) return;
+  if (typeof h$isNode !== "undefined") return;

I put in some of the work to port this to improved-base, but I need to switch gears, so I put up my WIP branch here: https://github.com/mgsloan/ghcjs-jquery/tree/improved-base

If anyone wants to carry this branch forward, let me know here! I'll hopefully revisit this in a week or two.

Consider blur - it's overloaded to either be a mutation or register an event handler. It is weird to me that the event handler thing is getting this name rather than the action, particularly as blur. To me, code with this reads really strangely without the on.

So, I'd say all jquery event registration things should start with on. I'm not changing this, for now. Maybe once improved-base stabilizes, stuff like this can get fixed up.

I apologize in advance for the poor description in this issue. I'm not really sure what the problem is, but I thought I would leave this here in case other people run into a similar problem.

I'm trying to use Flot, a JQuery-based library for plotting charts. If I use ghcjs-jquery, the Flot code (jquery.flot.js) does not load properly.** That is, it does not extend the jQuery object with its functionality, such as adding a plot function. If I use the simple FFI below (with a static jquery.js and without using ghcjs-jquery), the Flot code works. I only need selectElement at this point.

type JQuery = JSRef JQuery_
data JQuery_

selectElement :: (MonadIO m, IsElement e) => e -> m JQuery
selectElement = liftIO . jq_selectElement . unElement . toElement

foreign import javascript unsafe "jQuery($1)" jq_selectElement :: JSRef Element -> IO JQuery

** Using ghcjs-jquery, I have seen Flot work intermittently (once in a while on refresh). With only the above, it works consistently.

My guess is that the JavaScript loading is somehow causing the problem. Our output JS is relatively large.

event handling is implemented by having a thread block on an MVar that is passed to JS. GHCJS sends a 'Thread blocked indefinitely on an MVar operationto the thread now, since nothing in the Haskell world has another reference to thatMVar`, which means that no further events will be processed.

This makes much of this library rather useless, so it should really be fixed.

Hey folks,

I was just wondering how come there is no ready FFI binding. Is this something automatically enforced by GHCJS or it's just an oversight?

Thanks a ton!

In the cabal file, ghcjs-dom has no version range and cabal install fails because it tries to use 0.2.1.0. Works with the previous version ghcjs-dom-0.1.1.3.
