Is there a way to invoke an anonymous function and have the function
itself returned?
What I am trying to do is attach an observer to an element, and at the
same time run the observer so that the initial state is set. My
javascript looks like this:
function toggleDetails () {
$$('.moreDetails').invoke( $F('showDetails') == 'y' ? 'hide' :
'show' );
}
$('showDetails').observe( 'change', toggleDetails );
toggleDetails();
Bascially, it adds a control to show the "moreDetails" sections of a
form when a toggle is set to "yes".
But I feel like this could be done in less code... maybe using an
anonymous function that is invoked as it is attached as an observer.
Something like this:
$('showDetails').observe( 'change', function () {
$$('.moreDetails').invoke( $F('showDetails') == 'y' ? 'hide' :
'show' );
}.invokeAndReturn() );
Where invokeAndReturn() is a method that calls "this", discards the
results, and then just returns "this".
Am I over complicating this?
Thanks for any help you can offer
