如何跟天数加颜色
小弟现在在做一个倒计时的小功能！！时间格式是三位数 var days = Math.floor(hours/24);
比如 210天 010天 009 天 ！现在是要对每个位数加颜色！days 就是这个三位数输出来的值！要的效果是这样子
比如当 210天时
当 010天时
当 009天时
现在的问题是 要怎么把dsys出来的值加颜色！还怎么设置他的格式是三位数 比如当是9 怎么变成 009

window.onload=function(){

var str="";
for(var i=0;i<d.length;i++){
str+=a[d.charAt(i)]

类似这样试试
