js获得当前日期时间(多种日期时间格式)

<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-????)
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
if (mytime<"23:30:00"){
   alert(mytime);
}
