一些比较简单的javascript:

function get_time() /**获取当前时间**/

{

var date=new Date();

var year="",month="",day="",week="",hour="",minute="",second="";

year=date.getYear();

month=add_zero(date.getMonth()+1);

day=add_zero(date.getDate());

week=date.getDay();

switch (date.getDay()) {

case 0:val="星期天";break

case 1:val="星期一";break

case 2:val="星期二";break

case 3:val="星期三";break

case 4:val="星期四";break

case 5:val="星期五";break

case 6:val="星期六";break

}

hour=add_zero(date.getHours());

minute=add_zero(date.getMinutes());

second=add_zero(date.getSeconds());

timetable.innerText=" "+year+"年"+month+"月"+day+"日"+hour+":"+minute+":"+second+" "+val;

}
