This time I will bring you js to implement refresh time in seconds, and js to implement refresh time in seconds. What are the precautions . Here is a practical case, let’s take a look. .
Principle: Use a timer, that is, setInterval(fn,i), to execute fn every i seconds.
The specific code is given below
1. The code is as follows:
<span style="font-size:14px;"><!DOCTYPE html> <html lang="zh-cn"> <head> <meta charset="UTF-8"> <title>用js实现每隔一秒刷新时间(含年月日时分秒)</title> <style> #time{background:#33F; color:white; height:30px; line-height:30px; padding:20px; font-size:18px; width:400px; text-align:center; margin:0 auto; margin-top:200px;} </style> </head> <body> <p id="time"></p> <script type="text/javascript"> setInterval(function(){ var time=new Date(); var year=time.getFullYear(); //获取年份 var month=time.getMonth()+1; //获取月份 var day=time.getDate(); //获取日期 var hour=checkTime(time.getHours()); //获取时 var minite=checkTime(time.getMinutes()); //获取分 var second=checkTime(time.getSeconds()); //获取秒 /****当时、分、秒、小于10时,则添加0****/ function checkTime(i){ if(i<10) return "0"+i; return i; } var box=document.getElementById("time"); box.innerHTML=year+"年"+month+"月"+day+"日 "+hour+":"+minite+":"+second; },1000); //setInterval(fn,i) 定时器,每隔i秒执行fn </script> </body> </html></span><span style="font-size:32px;"> </span>
