js时钟代码

适用于ie6,7,8.及firefox.这段代码主要难点在于取得当时秒。ie不支持getSeconds()

function js_time(){
  var now=new Date();
  y=now.getFullYear();
  m=now.getMonth()+1;
  d=now.getDate();
  hh=now.getHours();
  mm=now.getMinutes();
  var ss = now.getTime() % 60000;
  ss = (ss - (ss % 1000)) / 1000;
  if(m<10) m='0'+m;
  if(d<10) d='0'+d;
  if(hh<10) hh='0'+hh;
  if(mm<10) mm='0'+mm;
  if(ss<10) ss='0'+ss;
  document.getElementById("#time").value=(y+"年"+m+"月"+d+"日"+" "+hh+":"+mm+":"+ss);
}
