Does anyone know how to have a checkbox change a normal text link into a strike through text link. And when the box is unchecked the stike through text link turns back into a regular link again.

I tried to code it here:

But I need for the strike through to disapear when the check box is unchecked. Similar to iGoogle.com or Netvibes.com to do list.
