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 (the author uses $(´#twittersearch´) )
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.
The statements that I used where these
$("#tab1 .container_twitter_status").empty();
$("#tab1 .container_twitter_status").liveTwitter('bacon', {limit: 5, rate: 30000});
and when want to stop
$("#tab1 .container_twitter_status").each(function(){console.log(this.twitter);});
$("#tab1 .container_twitter_status").each(function(){ this.twitter.stop(); });
thanks in advance, Richard

$('#myDiv').each(function(){});does the callback function with every matched DOM node asthis.The functionality in the liveTwitter plugin is wrapped up in an object and assigned to the DOM node on
.twitter, sothisin this context is the DOM node itself.These would be equivalent:
$('#myDiv').get(0).twitter.stop();document.getElementById('myDiv').twitter.stop();I just tested the example code, and it should work as intended.
Are you using the same selector when you call the stop function? You could try doing:
$("#tab1 .container_twitter_status").each(function(){console.log(this.twitter);});and see if Firebug/Webkit returns Object or null.
Also, if you don’t want it to refresh automatically, just pass
refresh: false:$("#twitterSearch").liveTwitter('bacon', {limit: 10, refresh: false});You can do this on the fly to disable refreshing temporarily:
$("#stuff").liveTwitter('banana', {refresh: false});$("#stuff").liveTwitter('banana', {refresh: true});
