I am trying to autoscroll to the botem of a page, and then back up again. I would like it to scroll down, wait about 5 sec, then scroll back up to the top, wait another 5 sec, then do the whole thing over again. Im a uber jscript noob so bare with me here What I have so far is below...

function start1 starts the scrolling down
function start2 starts the scrolling up
function stop1 halts scrolling
function top1 just leeps back up top

i would like this to happen body onload, and it just does its thing.. i know this is simple, but im not at the simple level quite yet
thanks in advance!

<SCRIPT LANGUAGE="JavaScript">

var timeout;
var y = 0;
var step = 4;

function start1(){
if (y < 0){
y=0;
}

window.parent.scroll(0,y);
y=y + step;

timeout=setTimeout("start1()",100);
}

function start2(){
if (y >=0 ){
window.parent.scroll(0,y);

y = y - step;
}

timeout=setTimeout("start2()",100);
}

function stop1(){
clearTimeout(timeout);
}

function top1(){
window.parent.scroll(0,0);

y=0;
}

</SCRIPT>

Try something like that:

 
function page_size() {
  var y, h;
  if(window.innerHeight && window.scrollMaxY)
    y = window.innerHeight + window.scrollMaxY;
  else if(document.body.scrollHeight)
    y = document.body.scrollHeight;
  else y = document.body.offsetHeight;
  if(window.innerHeight) h = window.innerHeight;
  else if(document.documentElement && document.documentElement.clientHeight)
    h = document.documentElement.clientHeight;
  else if(document.body) h = document.body.clientHeight;
  return ((y > h) ? y + 20 - h : false);
}
function init_scroll() {
  init_scroll.height = page_size();
  if(init_scroll.height) {
    init_scroll.y = 0;
    init_scroll.step = 50;
    make_scroll();
  }
}    
function make_scroll() {
  var y = (init_scroll.y += init_scroll.step);
  if(y >= 0 && y <= init_scroll.height) {
    window.scroll(0, y);
    setTimeout(make_scroll, 10);
  }
  else {
    init_scroll.step = -init_scroll.step;
    setTimeout(make_scroll, 2000);
  }
}
onload = init_scroll;
