Y.delegate('containerselector', handlerfunction, 'target selectors');

so for example

Y.delegate('#containerid', myhandler, 'a.classname');

where myhandler could be

var myhandler = function(e){
var clickedOn = e.currentTarget;
alert('are you sure you want to go to ' + clickedOn.get('src'));

};

See these for more info:

This is incorrect, the delegate method's signature is:
EventHandle delegate ( type , fn , el , spec , context , args* )

Code:
Y.delegate('click', handleFn, '#container', 'a.external');
