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();
