Js获取处理日期时间

var myDate = new Date();myDate.getYear(); //当前年份(2位)

myDate.getFullYear(); //获取完整的年份(4位,1970-????) // firefox 和 ie 兼容，调用getYear() 则不行

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

js获取日期、兼容IE,FIREFOX,OPERA

Firefox与IE的兼容性问题一直存在，以前一般碰到的都是表现上的兼容性问题，这回却在Javascript上出现了问题，一个在IE和Opera上都能正常显示的获取日期的函数（显示结果为 2009-01-13），在firefox里的结果却显示不正常（显示结果为 109-01-13），查了下原因，原来是Firefox的getYear函数获取到的值是当前年份减去1900的值。

解决方法就是判断获取的年份是否小于1900，如果小于的话就加1900

具体的获取日期的代码如下：

de>varde> de>today=de>de>newde> de>Date(); de>

de>date=today.getDate(); de>

de>month=today.getMonth(); de>

de>month=month+1; de>

de>ifde>de>(month<=9) de>

de>month=de>de>"0"de>de>+month; de>

de>year=today.getYear(); de>

de>ifde>de>(year<1900)year+=1900;  de>de>//Firefox下的兼容处理 de>

de>varde> de>nowDate=year+de>de>'-'de>de>+month+de>de>'-'de>de>+date;de>
