废话少说，直接上代码

复制代码 代码如下:

//获取当前时间：

var myDate = new Date();//当前时间

var year = myDate.getFullYear();//当前年份

var month = myDate.getMonth() + 1;//当前月份

var day = myDate.getDate();//当前日

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

var oneDay = 1000 * 60 * 60 * 24;

//获取最近一周的日期

var lastDate = new Date(myDate - oneDay * 6);

var lastYear = lastDate.getFullYear();

var lastMonth = lastDate.getMonth() + 1;

var lastDay = lastDate.getDate();

//获取当前月的最后一天

var day = new Date(year ,month , 0);

var lastdate = day.getDate();//当前月的最后一天

//获取最近N个月的日期

var lastDate = new Date(myDate - oneDay * myDate.getDate());

lastDate = new Date(lastDate - N * oneDay * (lastDate.getDate() - 1));

var lastYear = lastDate.getFullYear();

var lastMonth = lastDate.getMonth() + 1;

var lastDay = lastDate.getDate();

//字符串转换为时间戳

var date="2014-12-06";

date = new Date(Date.parse(date.replace(/-/g, "/")));

date = date.getTime();
