JS获得时间

<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-????) 用于取火狐显示年份，IE同时可用
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
