Sonderzeichen in einem String suchen

[Kathrin]

ja das habe ich auch gemacht aber meine funktion funktioniert nicht

//Array fuer die nicht Sonderzeichen
 var andereZeichen = new Array("A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z","a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z",0,1,2,3,4,5,6,7,8,9);

for(var x = 0; x < andereZeichen.length ; x++) {
  var ergebnis = pass.search(andereZeichen[x]);
  if(ergebnis == -1) {
    erfuelltCharacterBoolean = true;
    break;
  }
  else {
    erfuelltCharacterBoolean = false;
  }
}
