7 Color Hyperinks Hover Effect

It is published by Shiraz Shakeel. You must have notices that how sometimes you find some blog's hyperlinks which change color on mouse hover. By default on mouse hover only a single color change is seen but now, it is changed from now you can change your link colors up to 7 colors. I have changed the code a bit for simplicity. This tutorial is really simple to follow and uses a JavaScript which we will save inside Blogger so there will be no external link at all. 

How To Add This??

1. Go to Blogger >> Layout >> Add a Gadget
2. Select HTML/Java Script
3. Add the Code Below

<script type='text/javascript'> //<![CDATA[ var rate = 20; if (document.getElementById) window.onerror=new Function("return true") var objActive; // The object which event occured in var act = 0; // Flag during the action var elmH = 0; // Hue var elmS = 128; // Saturation var elmV = 255; // Value var clrOrg; // A color before the change var TimerID; // Timer ID if (document.all) { document.onmouseover = doRainbowAnchor; document.onmouseout = stopRainbowAnchor; } else if (document.getElementById) { document.captureEvents(Event.MOUSEOVER | Event.MOUSEOUT); document.onmouseover = Mozilla_doRainbowAnchor; document.onmouseout = Mozilla_stopRainbowAnchor; } function doRainbow(obj) { if (act == 0) { act = 1; if (obj) objActive = obj; else objActive = event.srcElement; clrOrg = objActive.style.color; TimerID = setInterval("ChangeColor()",100); } } function stopRainbow() { if (act) { objActive.style.color = clrOrg; clearInterval(TimerID); act = 0; } } function doRainbowAnchor() { if (act == 0) { var obj = event.srcElement; while (obj.tagName != 'A' && obj.tagName != 'BODY') { obj = obj.parentElement; if (obj.tagName == 'A' || obj.tagName == 'BODY') break; } if (obj.tagName == 'A' && obj.href != '') { objActive = obj; act = 1; clrOrg = objActive.style.color; TimerID = setInterval("ChangeColor()",100); } } } function stopRainbowAnchor() { if (act) { if (objActive.tagName == 'A') { objActive.style.color = clrOrg; clearInterval(TimerID); act = 0; } } } function Mozilla_doRainbowAnchor(e) { if (act == 0) { obj = e.target; while (obj.nodeName != 'A' && obj.nodeName != 'BODY') { obj = obj.parentNode; if (obj.nodeName == 'A' || obj.nodeName == 'BODY') break; } if (obj.nodeName == 'A' && obj.href != '') { objActive = obj; act = 1; clrOrg = obj.style.color; TimerID = setInterval("ChangeColor()",100); } } } function Mozilla_stopRainbowAnchor(e) { if (act) { if (objActive.nodeName == 'A') { objActive.style.color = clrOrg; clearInterval(TimerID); act = 0; } } } function ChangeColor() { objActive.style.color = makeColor(); } function makeColor() { // Don't you think Color Gamut to look like Rainbow? // HSVtoRGB if (elmS == 0) { elmR = elmV; elmG = elmV; elmB = elmV; } else { t1 = elmV; t2 = (255 - elmS) * elmV / 255; t3 = elmH % 60; t3 = (t1 - t2) * t3 / 60; if (elmH < 60) { elmR = t1; elmB = t2; elmG = t2 + t3; } else if (elmH < 120) { elmG = t1; elmB = t2; elmR = t1 - t3; } else if (elmH < 180) { elmG = t1; elmR = t2; elmB = t2 + t3; } else if (elmH < 240) { elmB = t1; elmR = t2; elmG = t1 - t3; } else if (elmH < 300) { elmB = t1; elmG = t2; elmR = t2 + t3; } else if (elmH < 360) { elmR = t1; elmG = t2; elmB = t1 - t3; } else { elmR = 0; elmG = 0; elmB = 0; } } elmR = Math.floor(elmR).toString(16); elmG = Math.floor(elmG).toString(16); elmB = Math.floor(elmB).toString(16); if (elmR.length == 1) elmR = "0" + elmR; if (elmG.length == 1) elmG = "0" + elmG; if (elmB.length == 1) elmB = "0" + elmB; elmH = elmH + rate; if (elmH >= 360) elmH = 0; return '#' + elmR + elmG + elmB; } //]]> </script>

Optional

You can change the rate of var rate = 20. It controls the speed with which hyperlinks change their color.
