/*
* Notes on hue
*
* This script uses hue rotation in the following manner:
* hue=0 is red (#FF0000)
* hue=60 is yellow (#FFFF00)
* hue=120 is green (#00FF00)
* hue=180 is cyan (#00FFFF)
* hue=240 is blue (#0000FF)
* hue=300 is magenta (#FF00FF)
* hue=360 is hue=0 (#FF0000)
*
* Notes on the script
*
* This script should function in any browser that supports document.getElementById
* It has been tested in Netscape7, Mozilla Firefox 1.0, and Internet Explorer 6
*
* Accessibility
*
* The script does not write the string out, but rather takes it from an existing
* HTML element. Therefore, users with javascript disabled will not be adverely affected.
* They just won't get the pretty colors.

/*
* splits par.firstChild.data into 1 span for each letter
* ARGUMENTS
* span - HTML element containing a text node as the only element

/*
* creates a rainbowspan object
* whose letters will be colored [deg] degrees of hue
* ARGUMENTS
* span - HTML element to apply the effect to (text only, no HTML)
* hue - what degree of hue to start at (0-359)
* deg - how many hue degrees should be traversed from beginning to end of the string (360 => once around, 720 => twice, etc)
* brt - brightness (0-255, 0 => black, 255 => full color)
* spd - how many ms between moveRainbow calls (less => faster)
* hspd - how many hue degrees to move every time moveRainbow is called (0-359, closer to 180 => faster)

Cara edit :

Cari perkataan GANTIKAN TULISAN INI DENGAN AYAT ANDA ... kemudian padam dan ganti dengan ayat power anda

Nota : jika anda ada menggunakan javascript yang mempunyai kata arahan yang sama dengan script ini.. kemungkinan script ini akan bug(tidak jadi)

Sekian
