/**
 * Funktion JumpAtSpecificValueLength
 *
 * Die Funktion setzt den Focus auf das Feld oToInput, wenn im Feld oFromInput
 * iValueLength Zeichen und als letztes Zeichen eine Ziffer eingegeben wurden. Der IF-Block
 * mit den keyCode-Abfragen wird benötigt, um ein Wechseln mit TAB bzw. SHIFT+TAB
 * zu ermöglichen, sofern bereits iValueLength Ziffern eingetragen sind.
 * 
 * <code>
 * 
 * <input ... id="FromInput" onKeyUp="JumpAtSpecificValueLength(this, 'ToInput', 5, oEvent);" ...>
 * <input ... id="ToInput">
 *
 * </code>
 *
 * Key-Codes:
 *	
 * 48  = 0 (normale Tastatur)
 * 57  = 9 (normale Tastatur)
 * 96  = 0 (Num-Block)
 * 105 = 9 (Num-Block)
 * 
 * @param object oFromInput ist das Feld, in dem die Zeichen gezählt werden
 * @param string sToInput ist das Feld, in das gesprungen werden soll
 * @param integer iValueLength ist die Anzahl der Zeichen, nach der gesprungen werden soll
 * @param object oEvent wird benötigt, um die Funktion Mozilla-Browser-kompatibel zu machen
