在js或jquery中獲取客戶端的日期時間都是非常簡單的，下面我們來看看它們分別介紹吧

原生態javascript獲取日期

複製代碼代碼如下:

<SCRIPT LANGUAGE="JavaScript">

var myDate = new Date();

    myDate.getYear();       //獲取當前年份(2位)

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

    myDate.getMonth();      //獲取當前月份(0-11,0代表1月)

    myDate.getDate();       //獲取當前日(1-31)

    myDate.getDay();        //獲取當前星期X(0-6,0代表星期天)

    myDate.getTime();       //獲取當前時間(從1970.1.1開始的毫秒數)

    myDate.getHours();      //獲取當前小時數(0-23)

    myDate.getMinutes();    //獲取當前分鐘數(0-59)

    myDate.getSeconds();    //獲取當前秒數(0-59)

    myDate.getMilliseconds();   //獲取當前毫秒數(0-999)

    myDate.toLocaleDateString();    //獲取當前日期

    var mytime=myDate.toLocaleTimeString();    //獲取當前時間

    myDate.toLocaleString( );       //獲取日期與時間

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

{

alert(mytime);

}

</SCRIPT>

基於jquery獲取日期

複製代碼代碼如下:

<!DOCTYPE html>

<html class="no-js">

<head>

    <meta charset="UTF-8">

    <title>當期時間</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簡單的獲取當前日期和時間</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>

可判斷早上好晚上好代碼

複製代碼代碼如下:

<script language="JavaScript">

//定義一個tick函數，以獲取系統的時間

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();

//獲取系統時間的小時數

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";

}

//獲取系統時間的分數

if(intMinutes<10)

{

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

}

else

minutes=intMinutes+":";

//獲取系統時間的秒數

if(intSeconds<10)

seconds="0"+intSeconds+" ";

else

seconds=intSeconds+" ";

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

Clock.innerHTML=timeString;

//每隔0.1秒鐘執行一次tick函數

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

}

window.οnlοad=tick;

</script>

下面這句是調用函數

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