Effect.toggle(boxID, ’slide’, { afterFinish: function(){ alert($(’parent’).getHeight()); } });

var mycallback = function() {
alert(”it now works!”);
};

Effect.toggle(boxID, ’slide’, { afterFinish:mycallback });

This worked fine, probably a slightly different problem (like me not doing it right) than the squish problem, but thanks for the reply nevertheless =)

Let me know if that solution works for you.

Effect.toggle(boxID, ’slide’, { afterFinish:alert($(’parent’).getHeight()) });

But the alert appears before the effect finishes…

The moment I come across a clean and elegant way to display the tree, I’m sure I’ll post about it.

In the meantime, with my current project I’ve moved away from a design involving displaying multiple levels/branches of a hierarchy all at once. I may revisit that concept, though right now I’m feeling good about the decision to start with everything collapsed and fetch a single level when an item is expanded.

I suppose I won’t know whether it’s truly more responsive to load an entire tree up front until I do some testing; both methods have trade-offs but the one-level-at-a-time display is simpler to implement.

My first suggestion would be to check your parentheses and brackets carefully. Since I wrote the above fix, the formatting of Effect.Squish code in Scriptaculous seems to have changed a bit.

Upgrading to the current script.aculo.us 1.7.0 this morning, then applying the Object.extend fix above, I was able to get afterFinish to fire after Effect.Squish completed.

Though it may be worth noting that, unlike Squish, Effect.Fold still fires afterFinish just before the element is completely gone.

The other suggestion I can offer is to check your callbacks with simple alert() calls; I say this as the modal alert dialogs essentially freeze script execution while they’re up, and it might be a bit easier to pinpoint when the callback is firing.

Hope that helps!

With a standard form you can do this:

<%= form_tag({ :action => :create }, { :onsubmit => 'function call' }) %>

However you probably noticed that if you try using :onsubmit with form_remote_tag(), your event handler gets replaced with the Ajax handler set up by Rails.

One option for Ajax may be to use the :before callback, which should allow you to call a function before the request is made. I haven’t tested it, but that may be what you’re looking for.

do you have any thoughts on this? any help would be much appreciated.

thanks,
