[houssam_ballout]

Hello All,Please can u help me, I've this script it works fine, but what I need is that when the page reaches the end, I want to make it begin from the first and so on Thanks in advance This is the code:<script language="javascript">function pageScroll() { window.scrollBy(0,50); // horizontal and vertical scroll increments scrolldelay = setTimeout('pageScroll()',1000); // scrolls every 100 milliseconds}</script>

To start at the beginning, the javaScript should be window.scroll(0,0), which will put the browser at x=0 and y=0 (top-left.)

I know that, but I mean when the page is scrolling down, when it reaches the end I want to make it go back again....

Oh? And where in your javaScript says it's at the end? I have a pretty good idea.

if(window.scroll = (this,this)) {// Do this.}

But since everyone has a different reso, it'll be hard to make this script.

It might take a little bit of tweaking, but something like this may help:

var body = document.body;if( (body.scrollHeight - body.clientHeight) <= body.scrollTop ){	// User is at the bottom of the page.}
