Code:<html><head><script language="JavaScript">

var colours=new Array("#780000", "#830000", "#880000", "#930000", "#990000", "#9f050d","#af150d",

"#bf250d", "#cf350d", "#df450d", "#ef550d", "#ff650d");


var aaa = "";
var ccc = "";
var ddd = "";

function defade(iii) {

ccc=eval("document.all." + iii + ".style");

for (i=11; i>0; i--) {

if (colours[i]==ccc.color) {

ccc.color=colours[i-1];
aaa=setTimeout("defade("+ iii +");", 100); }}}



function fade(iii) {

ccc=eval("document.all." + iii + ".style");

for (i=0; i<=10; i++) {

if (colours[i]==ccc.color) {

ccc.color=colours[i+1];
aaa=setTimeout("fade("+ iii +");", 100); }}}


</script>

</head><body>


<a href="#" name="link1" onmouseover="fade(this.name)" onmouseout="defade(this.name)"

style="color:#780000">Test link</a>

</body>
</html>


It works just one step, like a usual a:hover rollover in CSS. IE returns a /";" sign required/ error in lines with "eval()". Without "eval()" it doesn't work at all. What's wrong? Thanks in advance for any help.

On more thing, it's the Timeout line that's the devil. Without it, it works without returning errors. What am I missing?

Another attempt:

Code:<html><head><script language="JavaScript">

var colours=new Array("#780000", "#830000", "#880000", "#930000", "#990000", "#9f050d","#af150d",

var aaa;
var ccc = "";
var ddd = "";
var eee = 0;
var ggg = 1;
var hhh = 1;
var lll;

function defade(iii) {

ggg=0
hhh=1
clearTimeout(aaa)

ccc=eval("document.all." + iii + ".style")

function defade1() {

if (ccc.color==colours[11] & hhh==1) {
ccc.color=colours[10];
lll=setTimeout("defade1()", 100)
}

if (ccc.color==colours[10] & hhh==1) {
ccc.color=colours[9];
lll=setTimeout("defade1()", 100)
}

if (ccc.color==colours[9] & hhh==1) {
ccc.color=colours[8];
lll=setTimeout("defade1()", 100)
}

if (ccc.color==colours[8] & hhh==1) {
ccc.color=colours[7];
lll=setTimeout("defade1()", 100)

What is it that you are trying to do?
I have a fade script but it'll fade all links and with the same colours. Would that work?

It works one step up and down on mouseover and mouseout while I'd like it to work all steps and each sequence just once. In this case, it would be from #780000 to #FF650D and stopping there on mouseouver and from #FF650D to #78000 and stopping there on mouseout. Something is wrong with the setTimeouts in my script and I can't achieve that.

Test this script, I added -1 in the color array to mark the end (Just add colors and put -1 last). Then set "speedin" for the speed of onmouseover fade and "speedout" for onmouseout. The script will fade more then one link up/down, drag the mouse over the 4 testlinkes and you will see. It will also start fade/defade from the current color if you leave the link and reenter before it has faded down. And added onfocus/onblur since I like to browse with keys and not the mouse.

Hope it will work as you wanted.

Code:<html>

<script type="text/javascript">

var colours=new Array("#780000", "#830000", "#880000", "#930000", "#990000", "#9f050d","#af150d",
"#bf250d", "#cf350d", "#df450d", "#ef550d", "#ff650d",-1)
var timers=new Array();
var speedin=1;
var speedout=200;

function getElement(id) {
return document.getElementById ? document.getElementById(id) :
document.all ? document.all(id) : null;
}

function fade(id,now) {
clearTimeout(timers[id]);
myobj=getElement(id);
if (isNaN(now)){
now=0;
for (i=0;colours[i]!=-1;i++){
if (myobj.style.color==colours[i]) { now=i; }
}
}
myobj.style.color=colours[now];
now++;
if (colours[now]!=-1){
timers[id]=setTimeout("fade('"+id+"',"+now+")",speedin);
}
}

function defade(id,now) {
clearTimeout(timers[id]);
myobj=getElement(id);
if (isNaN(now)){
now=-1;
for (i=0;colours[i]!=-1;i++){
if (myobj.style.color==colours[i]) { now=i; }
}
if (now==-1) { now=i; }
}
myobj.style.color=colours[now];
now--;
if (now!=-1){
