Danke, aber....

Weiß ich leider nicht; ich habe das bisher so verwendet. Zum Beispiel in einer kleinen Funktion zum scrollen des Inhalts eines HTML-Elements:

---

/**
 * set up interval (or stop it) to scroll an element (using the mover()-function)
 *
 * @param String elemId - id of HTML-element, that should be scrolled
 * @param int direction - the direction to scroll (0 => UP; 1 => DOWN)
 * @param boolean status - selects wether to start or stop the interval;
 *   ('true' on mouseover, 'false' on mouseout)
 */
function scroll(elemId, direction, status, speed)
{
 elem = document.getElementById(elemId);
 if(status == true) {
  // using anonymous function to send object as paramter, set interval-speed here
  activeScroller[elemId] = window.setInterval(function(){mover(elem, direction);}, 100);
 }
 else {
  window.clearInterval(activeScroller[elemId]);
 }
}

/**
 * scroll down an given HTML-element into direction by 10 Pixel
 *
 * @param Element elem - the given HTML-element (as JS-object)
 * @param int direction - the direction to scroll (0 => UP; 1 => DOWN)
 */
function mover(elem, direction) {
 if(direction == 0) {
  elem.scrollTop -= 10;
 }
 else {
  elem.scrollTop += 10;
 }
}

<img src="arr_up.gif" alt="scroll up" onmouseover="scroll('mytextbox', 0, true);" onmouseout="scroll('mytextbox', 0, false);" />

<img src="arr_down.gif" alt="scroll down" onmouseover="scroll('mytextbox', 1, true);" onmouseout="scroll('mytextbox', 1, false);" />

Bis denn dann,
