获取日期对象中的指定部分,js1.6开始加入toLocaleFormat的方法,但是IE只支持JS1.3,所以不支持此方法:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>无标题文档</title></head><body> <script type="text/javascript" language="javascript">     var now=new Date();      //得到系统当前时间 var strDate=now.getFullYear()+"-"+now.getMonth()+"-"+now.getDate(); var strTime=now.getHours()+":"+now.getMinutes()+":"+now.getSeconds()+":"+now.getMilliseconds(); document.write("现在的时间是:"+strDate+"   "+strTime+"<br>"); document.write("今天是星期"+now.getDay()+"<br>");  </script></body></html>


============================================================

设置日期对象中的指定部分:

注意toLocaleDateString()方法

与:toLocaleString()方法的不同,2者虽然都是显示本地时,但是显示格式不同

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>无标题文档</title></head><body> <script type="text/javascript" language="javascript">     var now=new Date();      //得到系统当前时间 document.write("当前时间为:"+now.toLocaleString()+"<br>");    now.setFullYear(now.getFullYear()-1); document.write("1年前的这个时候:"+now.toLocaleString()+"<br>");   now.setMonth(now.getMonth()+1); document.write("1个月后:"+now.toLocaleDateString()+"<br>");  </script></body></html>


===================================================

对象中带有参数:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>无标题文档</title></head><body> <script type="text/javascript" language="javascript">     var date1=new Date(2009,3,19);  var date2=new Date(2009,3,19,17,48,2);  document.write("date1为:"+date1.toLocaleString()+"<br>");  document.write("date2为:"+date2.toLocaleString()+"<br>"); document.write("date2另外一种显示为:"+date2.toLocaleDateString()+"<br>");  </script></body></html>
