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
