How to stop event delegation(obvious fact #12132)

This was a question I got in the office today and there is no shame in asking it:

I am using Event Delegation on one of my products and I need to stop the main handler on the body from firing when I click a certain button. How do I do that?

The answer is of course to use stopPropagation() or cancelBubble(), both nicely wrapped in YAHOO.util.Event.stopPropagation(): HTML:

JavaScript:

YAHOO.util.Event.onContentReady('buttons',function(){
YAHOO.util.Event.on(document.body,'click',function(e){
var t = YAHOO.util.Event.getTarget(e);
snitch('It was the ' + t + ' that was clicked
');
});
YAHOO.util.Event.on('tease','click',function(e){
snitch('that was the first button
');
YAHOO.util.Event.stopPropagation(e);
});
YAHOO.util.Event.on('tease2','click',function(e){
snitch('that was the second button
');
});
function snitch(msg){
document.getElementById('littlesnitch').innerHTML += msg;
}
});
