js随机改变背景颜色

这个程序里面，最让我感觉不错的是：

1.   var r,g,b;  
2.   r = decToHex(randomNumber(256)-1);  
3.   g = decToHex(randomNumber(256)-1);  
4.   b = decToHex(randomNumber(256)-1);  
5.   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();
