JavaScript实现仿flash动感闪烁文字.

出处链接:http://www.5code.net

var arr = ["yellow","pink","green","orange","blue","#ccc","#ddd","black","#c00","#d122b2","#78336c","#0461a2","#d9764f","#1bae17","#13b5c4","#a100fe","red"];

以上是收集自己喜欢的颜色.

for(var i=0; i<arr.length; i++){
						colors.style.background= arr[Math.floor(Math.random() * (17+1))];
				 }

然后遍历这些颜色,让colors.style.background等于随机循环的arr[i].

最后通过setInterval方法重复执行randomChangeBG()函数里面的代码.

Math对象
