split jquery chain in two parts for matching / not matching conditions

[tex@…]

There are cases where you want to affect two sets of elements, matching and not matching. here is an example:

<label><input type='radio' name='onOff' value='on'></input>on</label>
<label><input type='radio' name='onOff' value='off'></input>off</label>

calling function either, for lack of a better name. This corresponds to ? : syntax, is there a name for that?

$('#onOff').either(
   '[value=on]',
   function() {
      // this should be passed to each()
      this.checked = true;
      alert( 'checking ' + this.name );
   },
  function() {
     this.checked = false;
  }
);

Anyway, if this sounds interesting to anyone else I'd be happy to send code, or maybe add it as a plugin. I find myself using this pattern fairly regularly, so.. thought it was worth a request.

This was brought up before, in the form of an if/else plugin. We opted not to include. However, I'm sure having a simple .either() plugin would be very useful to a number of people.
