window.setInterval('showTime()',1000);
function showTime(){
var enabled = 0;
today = new Date();
var day;
var date;
if(today.getDay()==0) day = "星期日"
if(today.getDay()==1) day = "星期一"
if(today.getDay()==2) day = "星期二"
if(today.getDay()==3) day = "星期三"
if(today.getDay()==4) day = "星期四"
if(today.getDay()==5) day = "星期五"
if(today.getDay()==6) day = "星期六"
date = (1900+today.getYear()) + "-" + (today.getMonth() + 1 ) + "-" + today.getDate() + " " +
