it's easiest to just assign it to local variable:
var f = function () {
$$('.moreDetails').invoke( $F('showDetails') == 'y' ? 'hide' :
'show' );
};
f();
$('showDetails').observe( 'change', f );
if you're running that script within another function it won't be
leaked to the global scope so you should be all set.
I'd expect you're probably doing something along these lines:
$(window).observe('load', function(){
var f = function () {
$$('.moreDetails').invoke( $F('showDetails') == 'y' ? 'hide' :
'show' );
};
f();
$('showDetails').observe( 'change', f );
});
