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。
