js随机改变背景颜色

这个程序里面，最让我感觉不错的是：

var r,g,b;

r = decToHex(randomNumber(256)-1);
g = decToHex(randomNumber(256)-1);
b = decToHex(randomNumber(256)-1);
document.bgColor = "#" + r + g + b;

这段生成颜色的代码相当的赞，很不错的算法~~~

JavaScript代码

function randomNumber(limit){

return Math.floor(Math.random()*limit);

}function decToHex(dec)

{
var hexStr =
"0123456789ABCDEF";
var low = dec % 16;

var high = (dec - low)/16;

hex = "" + hexStr.charAt(high) + hexStr.charAt(low);

return hex;

}function randomBgColor()

{
var r,g,b;
r = decToHex(randomNumber(256)-1);
g = decToHex(randomNumber(256)-1);
b = decToHex(randomNumber(256)-1);
document.bgColor = "#" + r + g + b;

}
randomBgColor();
