Problema passaggio parametri di una textarea

[erlupacchiotto]

Premetto che sono alle prime armi di javascript, sto' cercando di modificare una funzione gia' esistente.
Ho necessita' che premendo un bottone, si passi il valore di una textarea ad una funzione che ne modifica il valore, riaggiornando il valore dellatextarea stessa.
Grazie per la collaborazione
ciao

this.btnList = {
....
    "pulisciword":    ['PulisciWord',          'PulisciWord',    	 'editor_action(this.id)',  'ed_link.gif'],
....

function editor_action(button_id) {
...
	    // insert link
if (cmdID.toLowerCase() == 'pulisciword'){
      editdoc == wordClean(editdoc);
    }
end function


function wordClean(wordData) {
         // make one line
         wordData = wordData.replace(/\r\n/g, ' ');
         return wordData;
		}

Il problema e' proprio come chiamare e riprendere il valore di wordClean

[Kreatore]

sarò ingorante ma...

1. non puoi passare una variabile senprima non la definisci.

2. non puoi riprenderla se non viene definita in modo assoluto(esterna alle funzioni).

3. perchè fai una chiamata ad una funzione quando potresti inserire la linea

worData.replace....

come

editdoc=wordData.repalce

[erlupacchiotto]

quindi scusami nel mio caso, cosa dovrei fare ?

  
  if (cmdID.toLowerCase() == 'pulisciword'){
      x == wordClean(y);
    }

dove wordClean e' la funzione che pulisce il campo textarea
cosa debbo mettere per x e per y ?

Grazie
ciao
