I have this neat ticker (different from the ones that look like a message bar, this one looks cool, no background, no border, just sits on the page with the other text) but I have two problems:

1) I got that the scroll width makes it start that many pixels from the left edge, but it also increases the width of my page to what could end up being thousands of pixels wide (it keeps growing as it scrolls). There must be some way of defining a right side margin for this thing too.

2) this thing is WAY SLOW and I can't figure out which parameter sets the speed.

I'd like to use this but only if the bugs can be fixed. Thanks.

the code is this:

<!-- STEP TWO: Insert the onLoad event handler into your BODY tag -->

<nobr>Doesn't this message scroller look great? You can even insert links like this: <a href="http://www.yahoo.com" target="_blank">yahoo.com</a> Now it repeats.</nobr>

Put this in the head and change r1 to what you want:


<!-- Begin
var l1 = 0; // left of ticker in pixel, or 0 to position relative
var t1 = 0; // top of ticker in pixel, or 0 to position relative
var r1 = 0; // right of ticker in pixel, or 0 to position relative
var w1 = 400; // width of ticker in pixel
var ie = document.all ? true : false;
var first = true;
var l2 = l1 + w1;
var l3 = l1 - l2;
var l = l2;
function tickinit() {
if (ie) {
if (l1 == 0 && t1 == 0) {
pos = document.all['tickpos'];
l1 = getLeft(pos);
t1 = getTop(pos);
}
ticktext.style.posTop = t1;
}
else {
if (l1 == 0 && t1 == 0) {
pos = document.anchors['tickpos'];
l1 = pos.x;
t1 = pos.y;
}
document.ticktext.pageY = t1;
}
l2 = l1 + w1;
l3 = l1 - l2;
l = l2;
setInterval('tick()', 10);
}
function getLeft(ll) {
if (ll.offsetParent)
return (ll.offsetLeft + getLeft(ll.offsetParent));
else
return (ll.offsetLeft);
}
function getTop(ll) {
if (ll.offsetParent)
return (ll.offsetTop + getTop(ll.offsetParent));
else
return (ll.offsetTop);
}
function getRight(ll) {
if (ll.offsetParent)
return (ll.offsetTop + getRight(ll.offsetParent));
else
return (ll.offsetTop);
}
function tick() {
l = l - 0.5;
if (l < l3) l = l2;
cl = l1 - l;
cr = l2 - l;
if (ie) {
ticktext.style.posLeft = l;
ticktext.style.posTop = t1;
ticktext.style.posTop = r1;
ticktext.style.clip = "rect(auto "+cr+"px auto "+cl+"px)";
if (first) ticktext.style.visibility = "visible";
}
else {
document.ticktext.pageX = l;
document.ticktext.clip.left = cl;
document.ticktext.clip.right = cr;
if (first) document.ticktext.visibility = "show";

hope this works
