Need a logical flow of javascript calls to execute like I want them... can't figure it out.

[Matthew]

Ok, this may seem like a really stupid code help request, but i've got
this funny little longstanding Javascript bug going on with Netscape
that I've finally nailed... but only if I can get these calls to run
like I want them... but I don't know how to parse this out.

What I need is for a function call to execute only once on a
onkeydown, with the other calls executed with each keydown...

So logically it would flow something like this:

onkeydown="runonce_onkeydown();run_each_keydownA();run_each_keydownA();"

Anyone can figure this out?

keydown="runonce_onkeydown();run_each_keydownA();run_each_keydownA();"

Should that be a B?

function initialOnKeyDown(element){
runonce_onkeydown();
afterInitialOnKeyDown();
element.onkeydown = afterInitialOnKeyDown;
}

function afterInitialOnKeyDown(){
run_each_keydownA();
run_each_keydownB();
}

onkeydown="initialOnKeyDown(this);"

Another less elegant, but equally useful solution:

var ran_once = false;

function keyDownAction(element){
if(!ran_once) {
runonce_onkeydown();
ran_once = true;
}
run_each_keydownA();
run_each_keydownB();
}

Ah, that's great. Cheers!
