获取时间的方法及常用时间类都是大家经常使用的,在本文为大家整理了一些,个人感觉还比较全,感兴趣的朋友可以收集下



 




复制代码代码如下:


$(function(){  
   
var mydate = new Date();  
   
var t=mydate.toLocaleString();  
   
/*alert(t);*/  
   
$("#time").text(t);  
   
$("#time").load("Untitled-1.html");  
   

});  
   
<P id="time">afwef</P>


获取JavaScript 的时间使用内置的Date函数完成 


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
