View Full Version : Rotators interferring with existing 'swap image'

Hi. I found a great tutorial on creating rotating images using the DW 'swap image' feature: http://www.communitymx.com/content/article.cfm?cid=651FF.

Thing is, I already had 'swap image' code in my code for some rollovers.

Now, the rollovers stick - the rotating images work just fine. Is this normal or can somebody suggest a solution?

My code for the script is:

<script type="text/javascript">
<!--
function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}
function MM_swapImgRestore() { //v3.0
var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
}

function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && d.getElementById) x=d.getElementById(n); return x;
}

function MM_swapImage() { //v3.0
var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3)
if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];}
}
// Comma separated list of images to rotate
var imgs = new Array('rotators/bar_1.jpg','rotators/bar_2.jpg','rotators/bar_3.jpg','rotators/bar_4.jpg');
// delay in milliseconds between image swaps 1000 = 1 second
var delay = 500;
var counter = 0;

function preloadImgs(){
for(var i=0;i<imgs.length;i++){
MM_preloadImages(imgs[i]);
}
}

function randomImages(){
if(counter == (imgs.length)){
counter = 0;
}
MM_swapImage('rotator', '', imgs[counter++]);
setTimeout('randomImages()', delay);
}
//-->
</script>

And the relevant body code is:

<body onload="preloadImgs();randomImages();">

I deleted all reference to my rollover images in the original body code. I feel I should not have done this? Thing is, everything works, but the rollovers stick.

No worries if you can't help - this probably looks a proper mess to sort out!:roll:

Thanks.

Why not use CSS for your rollovers and the javascript for your image rotator? If not check out JQuery framework as an option to keep your code from conflicting.
