用javascript代码在当前页面中实时显示当前时间。
代码如下：
<html> <head> <title>JavaScript 实时显示当前时间-www.jbxue.com</title> </head> <body> <script language="javascript"> function showtime() { var today,hour,second,minute,year,month,date; var strDate ; today=new Date(); var n_day = today.getDay(); switch (n_day) { case 0:{ strDate = "星期日" }break; case 1:{ strDate = "星期一" }break; case 2:{ strDate ="星期二" }break; case 3:{ strDate = "星期三" }break; case 4:{ strDate = "星期四" }break; case 5:{ strDate = "星期五" }break; case 6:{ strDate = "星期六" }break; case 7:{ strDate = "星期日" }break; } year = today.getYear(); month = today.getMonth()+1; date = today.getDate(); hour = today.getHours(); minute =today.getMinutes(); second = today.getSeconds(); if(month<10) month="0"+month; if(date<10) date="0"+date; if(hour<10) hour="0"+hour; if(minute<10) minute="0"+minute; if(second<10) second="0"+second; document.getElementById('time').innerHTML = year + "年" + month + "月" + date + "日 " + strDate +" " + hour + ":" + minute + ":" + second; //显示时间 setTimeout("showtime();", 1000); //设定函数自动执行时间为 1000 ms(1 s) } </script> <div id="time"></div> <script language="javascript"> showtime();</script> </body> </html>
