Plaats onderstaande code tussen de head tags van je pagina;

<SCRIPT LANGUAGE="JavaScript"> //http://www.anouksweb.nl <!-- Begin function banner(imgSource,url,alt,chance) { this.imgSource = imgSource; this.url = url; this.alt = alt; this.chance = chance; } function dispBanner() { with (this) document.write("<A HREF=" + url + "><IMG SRC='" + imgSource + "' WIDTH=468 HEIGHT=60 BORDER=0 ALT='" + alt + "'></A>"); } banner.prototype.dispBanner = dispBanner; banners = new Array(); //eerste banner met url en omschrijving banners[0] = new banner("http://www.anouksweb.nl/banners/anouk_468_60.gif", "http://www.anouksweb.nl target='_blank'", "Start voor webmasters", 10); //tweede banner met url en omschrijving banners[1] = new banner("http://www.alphamegahosting.com/framework/data/reseller/banners/hosting_banner007.gif", "http://www.alphamegahosting.com/2/nl/p-af=55092 target='_blank'", "Websitehosting", 30); //derde banner met url en omschrijving banners[2] = new banner("http://www.anouksweb.nl/adverteren/banner01.gif", "http://www1.linkcounter.be/uit.php?id=9488 target='_blank'", "Webmastercity.nl", 20); sum_of_all_chances = 0; for (i = 0; i < banners.length; i++) { sum_of_all_chances += banners[i].chance; } function randomBanner() { chance_limit = 0; randomly_selected_chance = Math.round((sum_of_all_chances - 1) * Math.random()) + 1; for (i = 0; i < banners.length; i++) { chance_limit += banners[i].chance; if (randomly_selected_chance <= chance_limit) { document.write("<A HREF=" + banners[i].url + "><IMG SRC='" + banners[i].imgSource + "' WIDTH=468 HEIGHT=60 BORDER=0 ALT='" + banners[i].alt + "'></A>"); return banners[i]; break; } } } // End --> </script>

Deze code plaats je tussen de body tags van je pagina, op de plek waar de bannerrotator weergegeven moet worden

<SCRIPT LANGUAGE="JavaScript"> <!-- Begin this_banner = randomBanner(); document.write("<br><br>Deze banner heeft " + (this_banner.chance / sum_of_all_chances) * 100 + "% kans om weergegeven te worden"); // This line may be removed // End --> </script>
