I have a video editing app that I'm working on where you can add
captions to your movie up to a total number of purchased captions.
When you reach that limit, I disable the buttons that add more
captions by using Element.stopObserving and changing the button image
to reflect this disabled nature.
Now the client would like me to add "purchase more" to the same
screen, so I would like to know if I can memoize the listener from an
element, disable it, and then re-enable it from memory later in the
same session. I know that this page will work the way it is if I
reload the page after a successful purchase of new captions, but it's
a big page, and I'd like to avoid that if I can.
Any ideas?
Thanks,
Walter
