这里有新鲜出炉的Javascript教程,程序狗速度看过来!

JavaScript客户端脚本语言

Javascript 是一种由Netscape的LiveScript发展而来的原型化继承的基于对象的动态类型的区分大小写的客户端脚本语言,主要目的是为了解决服务器端语言,比如Perl,遗留的速度问题,为客户提供更流畅的浏览效果。


用js实现的日期与时间的代码,但代码较多,喜欢的朋友可以研究 下,正规的使用建议用phperz之前发布的内容。
JS 显示当前日期

 
<script language="Javascript"> 
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); 
</script> 


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("<div id='rili' style='position:absolute;width:140px;left:200px;top:50px;'>") 
document.write("<TABLE width='217' BORDER='0' CELLSPACING='0' CELLPADDING='2' BGCOLOR='#0080FF'>") 
document.write("<TR>"); 
document.write(" <TD> "); 
document.write(" <table border='0' cellspacing='1' cellpadding='2' bgcolor='Silver'>"); 
document.write(" <TR><th colspan='7' bgcolor='#C8E3FF'>"); 
document.writeln(" <FONT STYLE='font-size:9pt;Color:#330099'>" + "公元 " + now.getYear() + "年" + monthNames[now.getMonth()] + " " + now.getDate() + "日 " + dayNames[now.getDay()] + "</FONT>"); 
document.writeln(" </TH></TR><TR><TH BGCOLOR='#0080FF'><FONT STYLE='font-size:9pt;Color:White'>日</FONT></TH>"); 
document.writeln(" <th bgcolor='#0080FF'><FONT STYLE='font-size:9pt;Color:White'>一</FONT></TH>"); 
document.writeln(" <TH BGCOLOR='#0080FF'><FONT STYLE='font-size:9pt;Color:White'>二</FONT></TH>"); 
document.writeln(" <TH BGCOLOR='#0080FF'><FONT STYLE='font-size:9pt;Color:White'>三</FONT></TH>"); 
document.writeln(" <TH BGCOLOR='#0080FF'><FONT STYLE='font-size:9pt;Color:White'>四</FONT></TH>"); 
document.writeln(" <TH BGCOLOR='#0080FF'><FONT STYLE='font-size:9pt;Color:White'>五</FONT></TH>"); 
document.writeln(" <TH BGCOLOR='#0080FF'><FONT STYLE='font-size:9pt;Color:White'>六</FONT></TH>"); 
document.writeln(" </TR><TR>"); 
column = 0; 
for (i=0; i<startDay; i++) { 
document.writeln("\n<TD><FONT STYLE='font-size:9pt'> </FONT></TD>"); 
column++; 
} 

for (i=1; i<=nDays; i++) { 
if (i == thisDay) { 
document.writeln("</TD><TD ALIGN='CENTER' BGCOLOR='#FF8040'><FONT STYLE='font-size:9pt;Color:#ffffff'><B>") 
} 
else { 
document.writeln("</TD><TD BGCOLOR='#FFFFFF' ALIGN='CENTER'><FONT STYLE='font-size:9pt;font-family:Arial;font-weight:bold;Color:#330066'>"); 
} 
document.writeln(i); 
if (i == thisDay) 
document.writeln("</FONT></TD>") 
column++; 
if (column == 7) { 
document.writeln("<TR>"); 
column = 0; 
} 
} 
document.writeln("<TR><TD COLSPAN='7' ALIGN='CENTER' VALIGN='TOP' BGCOLOR='#0080FF'>") 
document.writeln("<FORM NAME='clock' onSubmit='0'><FONT STYLE='font-size:9pt;Color:#ffffff'>") 
document.writeln("现在时间:<INPUT TYPE='Text' NAME='face' ALIGN='TOP'></FONT></FORM></TD></TR></TABLE>") 
document.writeln("</TD></TR></TABLE></div>"); 
} 

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:
 
<html> 
<script language="JavaScript" type="text/javascript" src="time.js"> </script> 
<body bgcolor="#FFFFFF" onLoad="startclock(); timerONE=window.setTimeout" text="#000000"> 
<script language="JavaScript" type="text/javascript"> 
calendar(); 
</script> 
</body> 
</html> 

这就OK了!
