原生态javascript获取日期
复制代码 代码如下:
<script language="JavaScript"><br>var myDate = new Date();<br> myDate.getYear(); //获取当前年份(2位)<br> myDate.getFullYear(); //获取完整的年份(4位,1970-????)<br> myDate.getMonth(); //获取当前月份(0-11,0代表1月)<br> myDate.getDate(); //获取当前日(1-31)<br> myDate.getDay(); //获取当前星期X(0-6,0代表星期天)<br> myDate.getTime(); //获取当前时间(从1970.1.1开始的毫秒数)<br> myDate.getHours(); //获取当前小时数(0-23)<br> myDate.getMinutes(); //获取当前分钟数(0-59)<br> myDate.getSeconds(); //获取当前秒数(0-59)<br> myDate.getMilliseconds(); //获取当前毫秒数(0-999)<br> myDate.toLocaleDateString(); //获取当前日期<br> var mytime=myDate.toLocaleTimeString(); //获取当前时间<br> myDate.toLocaleString( ); //获取日期与时间<br>if (mytime<"23:30:00")<br>{<br>alert(mytime);<br>}<br></script>
基于jquery获取日期
复制代码 代码如下:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
js简单的获取当前日期和时间
<script type="text/javascript"><br> $(document).ready(function(){<br> setInterval(showTime, 1000); <br> function timer(obj,txt){<br> obj.text(txt);<br> } <br> function showTime(){ <br> var today = new Date();<br> var weekday=new Array(7)<br> weekday[0]="星期一"<br> weekday[1]="星期二"<br> weekday[2]="星期三"<br> weekday[3]="星期四"<br> weekday[4]="星期五"<br> weekday[5]="星期六"<br> weekday[6]="星期日" <br> var y=today.getFullYear()+"年";<br> var month=today.getMonth()+"月";<br> var td=today.getDate()+"日";<br> var d=weekday[today.getDay()];<br> var h=today.getHours();<br> var m=today.getMinutes();<br> var s=today.getSeconds(); <br> timer($("#Y"),y);<br> timer($("#MH"),month); <br> timer($("#TD"),td); <br> timer($("#D"),d);<br> timer($("#H"),h);<br> timer($("#M"),m);<br> timer($("#S"),s);<br> } <br> })<br> </script>
可判断早上好晚上好代码
复制代码 代码如下:
<script language="JavaScript"><br>//定义一个tick函数，以获取系统的时间<br>function tick()<br>{<br>var year,month,day,hours,minutes,seconds,ap;<br>var intYear,intMonth,intDay,intHours,intMinutes,intSeconds;<br>var today;<br>today=new Date();<br>intYear=today.getYear();<br>intMonth=today.getMonth()+1;<br>intDay=today.getDate();<br>intHours=today.getHours();<br>intMinutes=today.getMinutes();<br>intSeconds=today.getSeconds();<br>//获取系统时间的小时数<br>if(intHours==0)<br>{<br>hours=intHours+":";<br>ap="凌晨";<br>}<br>else if(intHours<12)<br>{<br>hours=intHours+":";<br>ap="早晨";<br>}<br>else if(intHours==12)<br>{<br>hours=intHours+":";<br>ap="中午";<br>}<br>else<br>{<br>intHours=intHours-12;<br>hours=intHours+":";<br>ap="下午";<br>}<br>//获取系统时间的分数<br>if(intMinutes<10)<br>{<br>minutes="0"+intMinutes+":";<br>}<br>else<br>minutes=intMinutes+":";<br>//获取系统时间的秒数<br>if(intSeconds<10)<br>seconds="0"+intSeconds+" ";<br>else<br>seconds=intSeconds+" ";<br>timeString=year+month+day+hours+minutes+seconds+ap;<br>Clock.innerHTML=timeString;<br>//每隔0.1秒钟执行一次tick函数<br>window.setTimeout("tick()",100);<br>}<br>window.onload=tick;<br></script>
下面这句是调用函数
