本文实例讲解了基于javascript实现随机颜色变化效果，分享给大家供大家参考，具体内容如下

<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> 
<title>随机颜色变化效果</title> 
<style type="text/css">
#thediv{
 width:100px;
 height:100px;
}
</style>
<script type="text/javascript"> 
var colorList=["#FFFF99","#B5FF91","#94DBFF","#FFBAFF","#FFBD9D","#C7A3ED","#CC9898","#8AC007"]; 
for(var i=0;i<colorList.length;i++){ 
 var bgColor=getColorByRandom(colorList); 
} 
function getColorByRandom(colorList){ 
 var colorIndex=Math.floor(Math.random()*colorList.length); 
 var color=colorList[colorIndex]; 
 colorList.splice(colorIndex,1); 
 return color; 
} 
window.onload=function(){
 var odiv=document.getElementById("thediv");
 function func(){
  odiv.style.backgroundColor=getColorByRandom(colorList);
 }
 setInterval(func,1000);
}
</script> 
</head> 
<body> 
<div id="thediv"></div>
</body> 
</html>

另一个js函数实现随机颜色：

function randomcolor()
{
var colorvalue=["0","2","3","4","5","6","7","8","9","a","b","c","d","e","f"],
colorprefix="#",
index;
for(var i=0;i < 6; i++){
index=Math.round(Math.random()*14);
colorprefix+=colorvalue[index];
}
return colorprefix;
}
var test=randomcolor();
alert(test);
