精彩的变色文字

脚本说明:
把如下代码加入<body>区域中
<script language="JavaScript">

/* This script was made by Erik.  You can contact him me worfy@geocities.com or at my homepage www.geocities.com/Area51/Corridor/4090. I know that it doesn't look pretty in the source code, but that couldn't be helped.  Feel free to modify this script in any way but please give me credit.  This is my first real script.
BTW  for you yankees, I spell colour with the U because I'm Canadain.*/

hexa = new MakeArray(16)
hexa[10] = "A"
hexa[11] = "B"
hexa[12] = "C"
hexa[13] = "D"
hexa[14] = "E"
hexa[15] = "F"

function MakeArray(n)
{
this.length = n
for (var i = 0; i <= n; i++)
this = i
return this
}

function colours(text){

var posa = 0
var posb = 1
while (posa <= text.length){
var r = Math.floor(Math.random() * 15)
