OK, so I solved the problem I think. I created a queue called
'dialogue' in the call to Effect.Scroll, and then put the following
code in my Rails application.js file:
Event.observe(window, 'load', function() {
Event.observe($('dialogue_window'), 'click', function()
{ Effect.Queues.get('dialogue').invoke('cancel'); })
Event.observe($('dialogue_window'), 'mousewheel', function()
{ Effect.Queues.get('dialogue').invoke('cancel'); })
Event.observe($('dialogue_window'), 'DOMMouseScroll', function()
{ Effect.Queues.get('dialogue').invoke('cancel'); })
});
This keeps the custom effect and the observer/handler code separate,
which seems right. It also appears to have the desired effect, at
least in FF3. I'll test it in other browsers tomorrow, but before I
do, does this approach seem reasonable?
