RV's free DHTML and JavaScript text and graphic scripts

VIRUS ATTACK!
This script simulates a virus attack (of the type experienced in the early days of viruses) on a page by slowly wiping out all the words on a page until there are none left. It is not running on this page for obvious reasons! See it in action using my F.A.Q. page.
This script has been tested on and shown to work with Internet Explorer 5+, Netscape 6+, Firefox 1.0 and Opera 7+
27-Apr-2005: First release.
STEP 1: Copy and paste the code below so that it sits between the <head> and </head> tags at the top of your web-page: <script type="text/javascript"> // <![CDATA[ var delay=5; // seconds until attack starts var seconds=60; // seconds until attack complete (from start) /**************************\ Mock-Virus Text Effect * * (c) 2005 mf2fm web-design * * http://www.mf2fm.com/rv * * DON'T EDIT BELOW THIS BOX * \**************************/ var colours=new Array("#090", "#0f0", "#6f6", "#cfc", "transparent"); var elems=new Array(); var chars=new Array(); var elmax=chmax=0; window.onload=function() { if (document.getElementById) { var i, j, txt, parent, span, words; getAllText(document.body); for (i=0; i<elmax; i++) { txt=elems[i].nodeValue; parent=elems[i].parentNode; words=elems[i].nodeValue.split(" "); for (j=0; j<words.length; j++) { span=document.createElement("span"); span.appendChild(document.createTextNode(words[j])); parent.insertBefore(span, elems[i]); if (j!=words.length-1) parent.insertBefore(document.createTextNode(" "), elems[i]); chars[chmax++]=span; } parent.removeChild(elems[i]); } virus(); }} function virus() { var i, t, j; for (i=0; i<chmax; i++) { t=1000(delay+secondsMath.random()); for (j=0; j<colours.length; j++) setTimeout('chars['+i+'].style.backgroundColor="'+colours[j]+'"', t+100j); setTimeout('chars['+i+'].style.visibility="hidden"', t+100j); } setTimeout('document.body.style.cursor="pointer";document.body.onclick=function(){top.location.href="http://www.mf2fm.com/rv/"};end()', 1000(delay+seconds)); } function end() { document.body.style.backgroundColor=colours[elmax=++elmax%colours.length]; setTimeout("end()", 100); } function getAllText(el) { if (el.nodeType==3 && !el.nodeValue.match(/^\s+$/)) elems[elmax++]=el; if (!el.childNodes.length) return; else for (var i=0; i<el.childNodes.length; i++) getAllText(el.childNodes[i]); } // ]]> </script> CLICK HERE to select the above script ready to paste it into your clipboard
THAT'S IT When your page loads, it should look like it is under attack by a virus (though of course it isn't really!)
