Or use Scriptaculous. It decouples the brush (XHTML tag) and the
JavaScript action to take. So you can either write:

html anchor
   onClick: (html update
      id: 'foo';
      callback: [ :r | ... ]);
   with: 'Click me'

or

html submitButton
   onClick: (html update
      id: 'foo';
      callback: [ :r | ... ]);
   with: 'Click me'

or even

html div
   onClick: (html update
      id: 'foo';
      callback: [ :r | ... ]);
   with: 'Click me'

for a clickable div-element. Moreover you could well replace the
onClick action with something completely different, like hiding an
element or starting an animation effect.

Cheers,
Lukas
