The context value is used internally by the Feeds jsapi. The only real
way to gain access to is to access the RESTful side of the API
directly via JSONP methods. In your case, I would suggest doing
something more like this:
function main(){
var callback=function(context){
return function(result){
if(!result.error){
console.log('Feed contains '+result.feed.entries.length+' posts');
console.log('local context is '+context);
}
}
}
for(var i in urls){
var feed=new google.feeds.Feed(urls[i]);
feed.load(callback(i));
}
}
