需要事先准备好0到9的数字图片，分别命名为0到9.png
以下是效果图:
代码部分:
<!DOCTYPE html>
<html>
<head>
<title></title>
<style type="text/css">
</style>
<script type="text/javascript">
window.οnlοad=function(){
var img=document.getElementsByClassName('num');
// 定义一个函数,当传入的参数小于10时,在参数前加上一个零
function toDou(num){
if(num<10)
return "0"+String(num);
else
return String(num);
}
function time(){
var date=new Date();
var hour=date.getHours();
var min=date.getMinutes();
var sec=date.getSeconds();
var str=toDou(hour)+toDou(min)+toDou(sec);
for(var i=0;i<img.length;i++){
// 所展示的图片地址由获取到的时间的每一位数值决定
img[i].src="../num-image/"+str.charAt(i)+".png";
}
}
time();
setInterval(time,1000);
}
</script>
</head>
<body>
<img src="" class="num">
<img src="" class="num">
<img src="../num-image/a.png">
<img src="" class="num">
<img src="" class="num">
<img src="../num-image/a.png">
<img src="" class="num">
<img src="" class="num">
</body>
</html>
