获取客户端电脑日期时间js代码(jquery)

  原生态javascript获取日期

  

复制代码 代码如下:

  <SCRIPT LANGUAGE="JavaScript">

  var myDate = new Date();

  myDate.getYear();       //获取当前年份(2位)

  myDate.getFullYear();   //获取完整的年份(4位,1970-????)

  myDate.getMonth();      //获取当前月份(0-11,0代表1月)

  myDate.getDate();       //获取当前日(1-31)

  myDate.getDay();        //获取当前星期X(0-6,0代表星期天)

  myDate.getTime();       //获取当前时间(从1970.1.1开始的毫秒数)

  myDate.getHours();      //获取当前小时数(0-23)

  myDate.getMinutes();    //获取当前分钟数(0-59)

  myDate.getSeconds();    //获取当前秒数(0-59)

  myDate.getMilliseconds();   //获取当前毫秒数(0-999)

  myDate.toLocaleDateString();    //获取当前日期

  var mytime=myDate.toLocaleTimeString();    //获取当前时间

  myDate.toLocaleString( );       //获取日期与时间

  if (mytime<"23:30:00")

  {

  alert(mytime);

  }

  </SCRIPT>

  基于jquery获取日期

  

复制代码 代码如下:

  <!DOCTYPE html>

  <html class="no-js">

  <head>

  <meta charset="UTF-8">

  <title>当期时间</title>

  <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>

  <style type="text/css">

  .date{height:100px;line-height:100px;margin:0 auto;font-family:Arial, Helvetica, sans-serif;font-size:40px;

  border:solid 1px #ccc;box-shadow:0 0 3px rgba(0,0,0,0.3) inset;border-radius:5px;text-shadow:1px 1px 2px rgba(0,0,0,0.3);}

  .date strong{padding:0 10px;display:inline-block;height:100px;border-right:solid 1px #ccc;}

  </style>

  </head>

  <body>

  <h1>js简单的获取当前日期和时间</h1>

  <p class="date">

  <strong id="Y"></strong>

  <strong id="MH"></strong>

  <strong id="TD"></strong>

  <strong id="D"></strong>

  <strong id="H"></strong>

  <strong id="M"></strong>

  <strong id="S"></strong>

  </p>

  <script type="text/javascript">

  $(document).ready(function(){

  setInterval(showTime, 1000);

  function timer(obj,txt){

  obj.text(txt);

  }

  function showTime(){

  var today = new Date();

  var weekday=new Array(7)

  weekday[0]="星期一"

  weekday[1]="星期二"

  weekday[2]="星期三"

  weekday[3]="星期四"

  weekday[4]="星期五"

  weekday[5]="星期六"

  weekday[6]="星期日"

  var y=today.getFullYear()+"年";

  var month=today.getMonth()+"月";

  var td=today.getDate()+"日";

  var d=weekday[today.getDay()];

  var h=today.getHours();

  var m=today.getMinutes();

  var s=today.getSeconds();

  timer($("#Y"),y);

  timer($("#MH"),month);

  timer($("#TD"),td);

  timer($("#D"),d);

  timer($("#H"),h);

  timer($("#M"),m);

  timer($("#S"),s);

  }

  })

  </script>

  </body>

  </html>

  可判断早上好晚上好代码

  

复制代码 代码如下:

  <script language="JavaScript">

  //定义一个tick函数,以获取系统的时间

  function tick()

  {

  var year,month,day,hours,minutes,seconds,ap;

  var intYear,intMonth,intDay,intHours,intMinutes,intSeconds;

  var today;

  today=new Date();

  intYear=today.getYear();

  intMonth=today.getMonth()+1;

  intDay=today.getDate();

  intHours=today.getHours();

  intMinutes=today.getMinutes();

  intSeconds=today.getSeconds();

  //获取系统时间的小时数

  if(intHours==0)

  {

  hours=intHours+":";

  ap="凌晨";

  }

  else if(intHours<12)

  {

  hours=intHours+":";

  ap="早晨";

  }

  else if(intHours==12)

  {

  hours=intHours+":";

  ap="中午";

  }

  else

  {

  intHours=intHours-12;

  hours=intHours+":";

  ap="下午";

  }

  //获取系统时间的分数

  if(intMinutes<10)

  {

  minutes="0"+intMinutes+":";

  }

  else

  minutes=intMinutes+":";

  //获取系统时间的秒数

  if(intSeconds<10)

  seconds="0"+intSeconds+" ";

  else

  seconds=intSeconds+" ";

  timeString=year+month+day+hours+minutes+seconds+ap;

  Clock.innerHTML=timeString;

  //每隔0.1秒钟执行一次tick函数

  window.setTimeout("tick()",100);

  }

  window.onload=tick;

  </script>

  下面这句是调用函数

  <div id="Clock"></div>
