代码如下:

var datelocalweek=new Array("星期日", "星期一", "星期二","星期三","星期四", "星期五","星期六");
var datelocalnow=new Date();
var datelocalyear=datelocalnow.getFullYear();
var datelocalmonth=(datelocalmonth="0"+(datelocalnow.getMonth()+1)).substr(datelocalmonth.length-2,2);
var datelocalday=(datelocalday="0"+datelocalnow.getDate()).substr(datelocalday.length-2,2);
var datelocalweekday=datelocalweek[datelocalnow.getDay()];
document.write(datelocalyear+"年"+datelocalmonth+"月"+datelocalday+"日"+" "+datelocalweekday);

效果如下图:

相应的JS如下：
代码如下:
//创建一个数组,用于存放每个月的天数
function montharr(m0, m1, m2, m3, m4, m5, m6, m7, m8, m9, m10, m11) {
this[0] = m0;
this[1] = m1;
this[2] = m2;
this[3] = m3;
this[4] = m4;
this[5] = m5;
this[6] = m6;
this[7] = m7;
this[8] = m8;
this[9] = m9;
this[10] = m10;
this[11] = m11;
}
//实现月历
function calendar() {
var monthNames = "JanFebMarAprMayJunJulAugSepOctNovDec";
var today = new Date();
var thisDay;
var monthDays = new montharr(31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31);
year = today.getYear() +1900;
thisDay = today.getDate();
if (((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0))
monthDays[1] = 29;
nDays = monthDays[today.getMonth()];
firstDay = today;
firstDay.setDate(1);
testMe = firstDay.getDate();
if (testMe == 2)
firstDay.setDate(0);
startDay = firstDay.getDay();
var dayNames = new Array("星期日","星期一","星期二","星期三","星期四","星期五","星期六");
var monthNames = new Array("1月","2月","3月","4月","5月","6月","7月","8月","9月","10月","11月","12月");
var now = new Date();
document.write("")
document.write("

var timerID = null;
var timerRunning = false;

function stopclock (){
if(timerRunning)
clearTimeout(timerID);
timerRunning = false;
}

//显示当前时间
function showtime () {
var now = new Date();
var hours = now.getHours();
var minutes = now.getMinutes();
var seconds = now.getSeconds()
var timeValue = " " + ((hours >12) ? hours -12 :hours)
timeValue += ((minutes < 10) ? ":0" : ":") + minutes
timeValue += ((seconds < 10) ? ":0" : ":") + seconds
timeValue += (hours >= 12) ? " 下午 " : " 上午 "
document.clock.face.value = timeValue;
timerID = setTimeout("showtime()",1000);//设置超时,使时间动态显示
timerRunning = true;
}

function startclock () {
stopclock();
showtime();
}

使用页面显示如下：
代码如下:




calendar();
