Question about [set|clear]Timeout()

[Ugo]

Hi guys,

sorry, I couldn't write a better Subject

I'd like to allow multiple launch of a function with the delayed execution
that breaks the launch previously scheduled
All writing one only function

what I designed is this:

function action( )
{
function myAct( )
{
alert( 'hi' );
action.timerID = null;
}
if( action.timerID )
{
clearTimeout( action.timerID );
action.timerID = null;
}

action.timerID = setTimeout( myAct, 500 );
}

as you can see, I'm using a "static private" variable to save
the reference timeout, avoiding global variables and/or closures, but
I "close" myAct() which is the real action that is launched ( sooner or
later)

What say, is there an other way "nice" to make this thing?
I should think more OOP (so others told me...), but I do not know how?
