1、第一种形式

 <html>
 <head>
 <title>时间</title>
 <script type="text/javascript">
setInterval("showtime()", 1000);
function showtime() {
var date = new Date();
var time = date.getHours() + ":" + date.getMinutes() + ":"
+ date.getSeconds();
document.getElementById("timeBox").value = time;
}
</script>
 </head>
 <body>
 <div style="text-align:center;">
  当前时间：<input type="text" name="timeBox" id="time" />
 </div>
 </body>

2、第二种形式

<html>
 <head>
 <title>时间</title>
 <script type="text/javascript">
 //获得当前时间,刻度为一千分一秒 
 function showLeftTime() {  
 var now = new Date();  
 var year = now.getFullYear();  
 var month = now.getMonth() + 1;  
 var day = now.getDate();  
 var hours = now.getHours();  
 var minutes = now.getMinutes();  
 var seconds = now.getSeconds();  
 document.all.show.innerHTML = "" + year + "年" + month + "月" + day + "日</br> " + hours + ":" + minutes + ":" + seconds + ""; 
 /https://img.qb5200.com/download-x/document.getElementById("show").innerHTML = "" + year + "年" + month + "月" + day + "日</br> " + hours + ":" + minutes + ":" + seconds + "";  
  
 //一秒刷新一次显示时间 
 setTimeout(showLeftTime, 1000); 
 } 
 
 </script> 
 </head>
 <body onload="showLeftTime()">
 <label id="show"></label><br/>
 <!-- <script type="text/javaScript">
