jsp页面中两种方法显示当前时间的简单实例_JSP编程_

 java.text.SimpleDateFormat simpleDateFormat = new java.text.SimpleDateFormat( "yyyy-MM-dd HH:mm:ss"); java.util.Date currentTime = new java.util.Date(); String time = simpleDateFormat.format(currentTime).toString(); //放到页面的head中} 

 function showtime() { var today; var hour; var second; var minute; var year; var month; var 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('clock').innerHTML = year + "年" + month + "月" + date + "日 " + strDate +" " + hour + ":" + minute + ":" + second; setTimeout("showtime();", 1000); }
