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>
