Page Auto Scroll Problem

[davidjohny]

Hi
I have a very simple problem but I do not know how to fix it.

I am using the auto scroll script from the below page
http://www.dynamicdrive.com/dynamicindex8/topscroll.htm

On page refresh it automatically scrol down the page and then
scroll up to top and then again scroll down and then again move up to Top and keep scrolling the page from top to down and then up and then down(LOOP process)


:: What I want ::
I want to just automatically scroll down the page and do not scroll up to Top again. DONE!

OR

After scrolling down wait for some 2 minutes and then auto scroll the page up to Top


Below is the script that I am using
Please some one fix this for me.

<script language="JavaScript1.2">

//change 1 to another integer to alter the scroll speed. Greater is faster
var speed=1
var currentpos=0,alt=1,curpos1=0,curpos2=-1
function initialize(){
startit()
}

function iecompattest(){
return (document.compatMode!="BackCompat")? document.documentElement : document.body
}

function scrollwindow(){
if (document.all)
temp=iecompattest().scrollTop
else
temp=window.pageYOffset
if (alt==0)
alt=1
else
alt=0
if (alt==0)
curpos1=temp
else
curpos2=temp
if (curpos1!=curpos2){
if (document.all)
currentpos=iecompattest().scrollTop+speed
else
currentpos=window.pageYOffset+speed
window.scroll(0,currentpos)
}
else{
currentpos=0
window.scroll(0,currentpos)
}
}
function startit(){
setInterval("scrollwindow()",10)
}
window.onload=initialize
</script>
========================================================

If you hate it going to top again, then remove the higlighted:

function scrollwindow(){
if (document.all)
temp=iecompattest().scrollTop
else
temp=window.pageYOffset
if (alt==0)
alt=1
else
alt=0

Hope it helps.

My apologies for not being with the thread. I've got a lot of work, anyway, that was my bad. Try to remove highlighted instead:

function scrollwindow(){
if (document.all)
temp=iecompattest().scrollTop
else
temp=window.pageYOffset
if (alt==0)
alt=1
else
alt=0
if (alt==0)
curpos1=temp
else
curpos2=temp
if (curpos1!=curpos2){
if (document.all)
currentpos=iecompattest().scrollTop+speed
else
currentpos=window.pageYOffset+speed
window.scroll(0,currentpos)
}
else{
currentpos=0
window.scroll(0,currentpos)
}
}

Hope it helps.

Here's a modified version of the script:

<script type="text/javascript">

//change 1 to another integer to alter the scroll speed. Greater is faster
var speed=1
var currentpos=0,alt=1,curpos1=0,curpos2=-1,
limit=100; // Set the limit here
function initialize(){
startit()
}

function iecompattest(){
return (document.compatMode!="BackCompat")? document.documentElement : document.body
}

function scrollwindow(){
if (document.all)
temp=iecompattest().scrollTop
else
temp=window.pageYOffset
if (alt==0)
alt=1
else
alt=0
if (alt==0)
curpos1=temp
else
curpos2=temp
if (curpos1!=curpos2){
if (document.all)
{
currentpos=(currentpos==limit)?iecompattest().scrollTop:iecompattest().scrollTop+speed;
}
else
currentpos=(currentpos==limit)?window.pageYOffset:window.pageYOffset+speed;
window.scroll(0,currentpos)
}
}
function startit(){
setInterval("scrollwindow()",10)
}
window.onload=initialize
</script>

Modifications were:

1. Added a limit (Highlighted sets the limit).
2. Scrolling stops on the set limit.

Hope that helps.

ooo thanks rangana. i will try it.

[spyderfyre3]

After the script scrolls down to the area set in the limit. Is there a way to make ti terminate so that people can scroll through the page without the autoscroll interfering? Basically, I went it to autoscroll once to the area set in the limit then stop and no more autoscrolling happens again unless the page is refreshed. Can someone help?

i am trying to use that script too but i would like a small change to it.

it is good as it is, i don't mind it scrolling to the bottom, but i would like the scrolling to stop once someone is clicking anywhere on the page.

That would be so great !

Your help is much appreciated.
