JQuery - One handler for multiple elements using variables

Question

I have two variables defined like this:

var $a = $('#a'),
    $b = $('#b');

How can I rewrite the following line using $a and $b?

$('#a, #b').click(function(e){...});

Answer 1

$([$a.get(0), $b.get(0)]).click(function(e) { ... });

Answer 2

$a.add($b).click(function(e){...});

add returns a new node set holding the union. $b can be "pretty much anything that $() accepts."
