var date = checkNum(today.getDate());
var day = today.getDay();
var hour = checkNum(today.getHours());
var minute = checkNum(today.getMinutes());
var second = checkNum(today.getSeconds());
switch(day) {
case 1:
day = "一";
break;
case 2:
day = "二";
break;
case 3:
day = "三";
break;
case 4:
day = "四";
break;
case 5:
day = "五";
break;
case 6:
day = "六";
break;
case 7:
day = "日";
break;
}
var fullTime = year+"-"+month+"-"+date+" "+"星期"+day+" "+hour+":"+minute+":"+second;
document.getElementById("showTime").innerHTML = fullTime;
setInterval('startTime()', 1000);
}catch(e) {
alert(e.description);
}
}
function checkNum(num) {
if(num<10) {
num = "0"+num;
}
return num;
}
