JS 显示当前日期与时间的代码

JS 显示当前日期

效果如下图:

相应的JS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("") 
document.write(""); 
document.write(" 
 "); 
document.write(" "); 
document.write(" "); 
document.writeln(" "); 
document.writeln(" "); 
document.writeln(" "); 
document.writeln(" "); 
document.writeln(" "); 
document.writeln(" "); 
document.writeln(" "); 
column = 0; 
for (i=0; i "); 
column  ; 
} 

for (i=1; i") 
column  ; 
if (column == 7) { 
document.writeln(""); 
column = 0; 
} 
} 
document.writeln("
"); 
document.writeln(" "   "公元 "   now.getYear()   "年"   monthNames[now.getMonth()]   " "   now.getDate()   "日 "   dayNames[now.getDay()]   ""); 
document.writeln(" 

日
一
二
三
四
五
六
") 
} 
else { 
document.writeln("
"); 
} 
document.writeln(i); 
if (i == thisDay) 
document.writeln("

") 
document.writeln("
") 
document.writeln("现在时间:


") 
document.writeln("


"); 
} 

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 = 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：

这就OK了！
