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);
以上就是本文的全部内容，希望对大家的学习javascript程序设计有所帮助。
