Disabling async is a terrible idea. Disabling it because of a slow
server is even worse. It will cause the browser to freeze until the
result comes back from the server. It guarantees a terrible user
experience.
You can achieve what you want by storing a reference to the callback
function in a variable, then changing that variable to hold a
reference to a different function when the appropriate conditions are
satisfied. I have an example at
<http://www.nickfitz.co.uk/examples/javascript/switching-functions.html>
although it's pure JavaScript, not jQuery; the code is all in the page
(not what I'd usually do, except for examples like this) so you can
view the source to see what it's doing.
Regards,
Nick.
