jquery只选择时间 jquery获取时间

$(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
