Is it possible to do live events in YUI, similar to jQuery's live events?

It doesn't currently seem as though there is a way to do live events in YUI similar to jQuery: http://api.jquery.com/live/

It sure would be nice if something like:

function handleClick(e) {
    // click!
}

YUI().use('node-base', function(Y) {
    Y.on("click", handleClick, ".foo");
});

caused handleClick to be fired when a node with the "foo" class was clicked on after being dynamically added to the DOM and sometime after the Y.on was evaluated. I feel like live events are one of jQuery's killer features that YUI lacks.

You can use YUI3's support for event delegation to accomplish the same thing.

YUI().use("node", "event", function(Y) {
    Y.delegate("click", function() {
        //click!
    }, Y.config.win, ".foo");
});

I think attaching that to the window is ok, you might need to attach it to the body instead.

Use Y.one("body") instead of Y.config.win in that case.

YUI 2's Event Utility also supports a delegate method.
