Left-Right scrolling window script

[Dan71121]

Hello All - I would like to edit this script so that it only scrolls from left to right once and then stops. Currently is scrolls, gets to the end, then returns back to the beginning and scroll again. Below is the script. Can anyone lend some assistance? Thanks, Dan

<script language="JavaScript1.2">

var speed=3
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().scrollLeft
else
temp=window.pageXOffset
if (alt==0)
alt=1
else
alt=0
if (alt==0)
curpos1=temp
else
curpos2=temp
if (curpos1!=curpos2){
if (document.all)
currentpos=iecompattest().scrollLeft+speed
else
currentpos=window.pageXOffset+speed
window.scroll(currentpos,0)
}
else{
currentpos=0
window.scroll(currentpos,0)
}
}
function startit(){
setInterval("scrollwindow()",10)
}
window.onload=initialize
</script>

Not even the demo of this script seems to work very well for me. Do you have a demo page of your own that does what you want except for stopping when you want it to?

PLEASE: Include the URL to your problematic webpage that you want help with.

Thanks for your help! Below is the URL.

Once you are on this page, select the Top, Right thumbnail (the one with the groom dipping the bride). This is the gallery I'm using as a test and it is working fine except it is repeating and I only want it to scroll across once.

Thanks again for your help! - Dan

Well, that certainly looks much nicer! OK, you have two choices. #1 is what I think you say you want, is to stop at the end of one scroll. To do that , change this line:

setInterval("scrollwindow()",10)

to:

scrollInt=setInterval("scrollwindow()",10)

and these lines:

else{
currentpos=0
window.scroll(currentpos,0)
}

to:

else
clearInterval(scrollInt)

The other possibility would be to have it stop and return to the beginning. For that, the first line change is still used but the second change needs to end up looking like so:

else{
clearInterval(scrollInt)
currentpos=0
window.scroll(currentpos,0)
}
