廢話少說，直接上代碼
復制代碼 代碼如下:
//獲取當前時間：
var myDate = new Date();//當前時間
var year = myDate.getFullYear();//當前年份
var month = myDate.getMonth() + 1;//當前月份
var day = myDate.getDate();//當前日
myDate.getYear(); //獲取當前年份(2位)
myDate.getFullYear(); //獲取完整的年份(4位,1970-????)
myDate.getMonth(); //獲取當前月份(0-11,0代表1月)
myDate.getDate(); //獲取當前日(1-31)
myDate.getDay(); //獲取當前星期X(0-6,0代表星期天)
myDate.getTime(); //獲取當前時間(從1970.1.1開始的毫秒數)
myDate.getHours(); //獲取當前小時數(0-23)
myDate.getMinutes(); //獲取當前分鐘數(0-59)
myDate.getSeconds(); //獲取當前秒數(0-59)
myDate.getMilliseconds(); //獲取當前毫秒數(0-999)
myDate.toLocaleDateString(); //獲取當前日期
var mytime=myDate.toLocaleTimeString(); //獲取當前時間
myDate.toLocaleString( ); //獲取日期與時間
var oneDay = 1000 * 60 * 60 * 24;
//獲取最近一周的日期
var lastDate = new Date(myDate - oneDay * 6);
var lastYear = lastDate.getFullYear();
var lastMonth = lastDate.getMonth() + 1;
var lastDay = lastDate.getDate();
//獲取當前月的最後一天
var day = new Date(year ,month , 0);
var lastdate = day.getDate();//當前月的最後一天
//獲取最近N個月的日期
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();
//字符串轉換為時間戳
var date="2014-12-06";
date = new Date(Date.parse(date.replace(/-/g, "/")));
date = date.getTime();
