Date 类型使用自 UTC 1970 年 1 月 1日 午夜 开始经过的毫秒数来保存日期。
 
创建日期对象
var now = new Date();//获取当前日期
 
Date.parse ( ) 接受一个表示日期的字符串参数,返回相应毫秒数。这个日期格式通常因地区而异。
实际上直接将日期字符串传给Date构造函数,也会后台先调用一下Date.parse(), 所以下面两条等价
 
var someDate = new Date(Date.parse("May 25, 2004"));
var someDate = new Date("May 25, 2004");
Date.UTC() 参数分别是 年份、月份(0-11)、天(1-31)、小时(0-23)、分钟、秒、毫秒数。省略的参数自动填充为0(天数为1)
同样这个UTC参数也可以直接传给Date构造函数
 
// 2005年5月5日下午5:55:55
var allFives = new Date(Date.UTC("2005, 4, 5, 17, 55, 55"));
var allFives = new Date("2005, 4, 5, 17, 55, 55");
 
 
Date.now() 返回当前时刻的那个毫秒数
 
继承的方法
 
Date的toLocaleString() 会返回日期和时间(会包含AM或PM) 但不包含时区信息
toString() 返回带有时区信息的日期时间

Date.valeuOf() 会返回日期的毫秒表示,因此日期大小是可以比较的
