This article mainly brings you an example of controlling time through js and moving it by itself second by second. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor to take a look, I hope it can help everyone.

1. The first form

 <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>
 <p style="text-align:center;">
  当前时间：<input type="text" name="timeBox" id="time" />
 </p>
 </body>
</html>

2. The second form

<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 + ""; 
 //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">
 showLeftTime();
 </script> -->
 </body>
</html>
