Javascript and nofollow

Hello, I'm new here
I have a question: how can I add the nofollow tag to the links I have in this banner rotator?

Code:

<script type="text/javascript"> 
<!-- Begin 
rnd.today=new Date(); 
rnd.seed=rnd.today.getTime(); 
 
function rnd() { 
        rnd.seed = (rnd.seed*9301+49297) % 233280; 
        return rnd.seed/(233280.0); 
}; 
 
function rand(number) { 
   var result = Math.ceil(rnd()*number); 
   if (!result)result++; 
        return result 
}; 
var ad_cnt2 = 2; 
var ad2 = rand(ad_cnt2); 
var link2; 
var adBanner2; 
var width2 
var height2 
if (ad2==1) { 
link2="http://TheSpiderWebSystem.com/greatnews"; 
adBanner2="http://thespiderwebsystem.net/spiderweb/s/728x90_wide.gif"; 
width2="728"; 
height2="90"; 
alt2=""; 
} 
if (ad2==2) { 
link2="/paidads.html"; 
adBanner2="/headerbanner.gif"; 
width2="728"; 
height2="90"; 
alt2=""; 
} 
document.write('<center><a href="' + link2 + '" target="_blank">'); 
document.write('<img src="' + adBanner2 + '" width=' + width2 + ' height=' + height2 + ' border=0 alt="' + alt2 + '"></a>'); 
document.write('</center>'); 
// End --> 
</SCRIPT>

Thank you!

You can, but theres no point. Only the search engine spiders will even listen to the rel="nofollow", and they don't listen to javascript, so it'll be like the banner doesn't even exist to the spider.
