Hi, I am using the liveTwitter
plugin
The problem is that I need to stop the
plugin from hitting the Twitter api.
According to the documentation I need to do this
$("#tab1 .container_twitter_status").each(function(){ this.twitter.stop(); });
Already, the each does not make sense on an id
and what does this refer to?
Anyway, I get an undefined error.
I will paste the
plugin code and hope it makes sense to somebody
MY only problem thusfar with this
plugin is that I need to be able to stop it.
thanks in advance, Richard
