JavaScript 动态时钟实现：基于图片序列的实时显示方案

核心代码与HTML结构

<script type="text/javascript">
 function todou(n){
 if(n<10){
  return '0'+n;
 }
 else {
  return ''+n;
 }
 }

 window.onload=function(){
 setInterval(function(){
   var date = new Date();
 
 var ma = document.getElementsByTagName('img');
  var str =todou(date.getHours())+todou(date.getMinutes())+todou(date.getSeconds());
  for(var i=0;i<ma.length;i++){
  ma[i].src='images/'+str[i]+'.png';
  }
  // alert(todou(date.getSeconds()));
 // var date = new Date();
 //alert(todou(date.getSeconds()));
 }  ,1000)
    
 }
