mouseout stopping a function

P: n/a
I have a function that is activated by a mouseover. The function
triggers an image rotation. I need to stop the rotation on the
mouseout but I don't know how to do this. the mouseover triggers the
rotate() function below. currently the mouseout produces the default
image but then it keeps cycling the other images.

<script language="javascript" type="text/javascript">
if(document.images) {
bubbles = new Image
off = new Image
bubbles.src = "images/bubbles.jpg"
off.src = "default.jpg"
}
else {
bubbles = ""
off = ""
}

adImages = new Array("images/whitemarble.jpg", "images/bubbles.jpg",
"images/oak.jpg")
thisAd = 0

imgCt = adImages.length

function rotate() {
if (document.images) {
thisAd++
if(thisAd == imgCt) {
thisAd = 0
}
document.ImgField.src=adImages[thisAd]
setTimeout("rotate()", 3 * 1000)
}
}
</script>

Do not use language="javascript" anymore

I don't know why you need the above code.
After all you are not preloading all images you use.
adImages = new Array("images/whitemarble.jpg", "images/bubbles.jpg",
"images/oak.jpg")
thisAd = 0

imgCt = adImages.length
use var in defining new variables.

var imgCt = adImages.length;
var myInterval;
etc.
var ImgField = document.getElementById('ImgField'); //see below

function rotate() {
if (document.images) {
thisAd++
if(thisAd == imgCt) {
thisAd = 0
}
You will see see number 0 last this way
document.ImgField.src=adImages[thisAd]
Use ID and getElementById() bor a better cross-browser compatibility:

ImgField.src=adImages[thisAd]
delete the below line:
setTimeout("rotate()", 3 * 1000)
}
}
</script>


and do:

onmouseover = 'myInterval = setInterval("rotate()", 3e3);'
onmouseout =
'clearInterval(myInterval);imgField.src="images/default.jpg"'

==============

Try in the <head>:

<script type='text/javascript'>
var adImages =
['images/whitemarble.jpg','images/bubbles.jpg','images/oak.jpg']
var imgCt = adImages.length;
var imageHolder = new Array;

for (var i=0;i<imgCt;i++){ // preloader
imageHolder[i] = new Image()
imageHolder[i].src = adImages[i]
}

var thisAd = 0;
var myInterval;

function rotate() {
document.getElementById('ImgField').src =
imageHolder[thisAd].src
if (++thisAd == imgCt) thisAd = 0
}
</script>

That worked, excellent!

Now I have to figure out how to make this work for 12 different sets of
rollovers. I know there's a way to do it with a more involved array
but I"m not that experienced.

There are 12 thumbs in a circle. the ImgField is in the center. when
one of the thumbs in the circle is moused over the center image,
ImgField, displays a rotation of samples of the thumb being rolled
over. mouseout produces the default image. What you gave me works
great! if I can make it for all 12 without writing a seperate function
for each thumb that would be great.

Thanks for your help! I might be able to feed my kids this week ;-)
