JS 显示当前日期与时间的代码

JS 显示当前日期

  

复制代码 代码如下:

  <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:

JS 显示当前日期与时间的代码

  相应的JS如下:

  

复制代码 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("<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'>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:

  

复制代码 代码如下:

  <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!
