NODEJS服务端项目调用
$ cnpm install date-utils require(‘date-utils‘);
nodejs版本要求>0.6
API :
Date.today(); // today, 00:00:00 Date.yesterday(); // yesterday, 00:00:00 Date.tomorrow(); // tomorrow, 00:00:00 Date.validateDay(day, year, month); // true/false whether a date is valid Date.validateYear(year); // true/false whether a year is valid Date.validateMonth(month); // true/false whether a month is valid Date.validateHour(hour); // true/false whether an hour is valid Date.validateMinute(minute); // true/false whether a minute is valid Date.validateSecond(second); // true/false whether a second is valid Date.validateMillisecond(millisecond); // true/false whether a millisecond is valid Date.compare(date1, date2); // -1 if date1 is smaller than date2, 0 if equal, 1 if date2 is smaller than date1 Date.equals(date1, date2); // true/false if date1 is equal to date2 Date.getDayNumberFromName(name); // su/sun/sunday - 0, mo/mon/monday - 1, etc Date.getMonthNumberFromName(name); // jan/january - 0, feb/february - 1, etc Date.isLeapYear(year); // true/false whether the year is a leap yearDate.get DaysInMonth(year, monthNumber); // number of days in the month 0-11
d.clone(); // returns a new copy of date object set to the same time
d.getMonthAbbr(); // abreviated month name, Jan, Feb, etc
d.getMonthName(); // fill month name, January, February, etcd.getUTCOffset(); // returns the UTC offset
d.getOrdinalNumber(); // day number of the year, 1-366 (leap year)
d.clearTime(); // sets time to 00:00:00d.setTimeToNow(); // sets time to current time
d.toFormat(format); // returns date formatted with:
// YYYY - Four digit year
// MMMM - Full month name. ie January
// MMM - Short month name. ie Jan
// MM - Zero padded month ie 01
// M - Month ie 1
// DDDD - Full day or week name ie Tuesday
// DDD - Abbreviated day of the week ie Tue
// DD - Zero padded day ie 08
// D - Day ie 8
// HH24 - Hours in 24 notation ie 18
// HH - Padded Hours ie 06
// H - Hours ie 6
// MI - Padded Minutes
// SS - Padded Seconds
// PP - AM or PM
// P - am or pmd.toYMD(separator); // returns YYYY-MM-DD by default, separator changes delimiter
d.between(date1, date2); // true/false if the date/time is between date1 and date2
d.compareTo(date); // -1 if date is smaller than this, 0 if equal, 1 if date is larger than thisd.equals(date); // true/false, true if dates are equal
d.isBefore(date); // true/false, true if this is before date passed
d.isAfter(date); // true/false, true if this is after date passed
d.getDaysBetween(date); // returns number of full days between this and passed
d.getHoursBetween(date); // returns number of hours days between this and passed
d.getMinutesBetween(date); // returns number of full minutes between this and passed
d.getSecondsBetween(date); // returns number of full seconds between this and passed
d.add({ milliseconds: 30,//这货忒牛逼了,解决了计算问题
minutes: 1,
hours: 4,
seconds: 30,
days: 2,
weeks: 1,
months: 3,
years: 2}); // adds time to existing time
d.addMilliseconds(number); // add milliseconds to existing time
d.addSeconds(number); // add seconds to existing time
d.addMinutes(number); // add minutes to existing time
d.addHours(number); // add hours to existing timed.addDays(number); // add days to existing time
d.addWeeks(number); // add weeks to existing time
d.addMonths(number); // add months to existing timed.addYears(number); // add years to existing time
d.remove(...); // same idea as for add//这里就是减法
d.removeMilliseconds(number); // ...// same API, just remove instead
静态调用必须要Date.today() 酱紫
动态方法 的 调用
var today=new Date();
today.add({});如此
其中我还自己添加了两个方法 用于动态获取第几周的功能

Date.prototype.getWeekOfYear = function() {//这天在本年是第几周 var onejan = new Date(this.getFullYear(), 0, 1); return Math.ceil((((this - onejan) / 86400000) + onejan.getDay() + 1) / 7);};Date.prototype.getWeekOfMonth=function () {//这天在本月是第几周 var day = this.getDate(); //get weekend date day += (this.getDay() == 0 ? 0 : 7 - this.getDay()); return Math.ceil(parseFloat(day) / 7);}; |
PS:一个月最多能有6个周序
