flex 日期处理工具类

 根据别人写了类，自己又增加了一部分，贴出来分享

 /*获得两个日期之差 */public static function getDateDiff(startDate:Date, endDate:Date):int {var diff:Number = (Number(endDate) - Number(startDate))/(3600000*24);return diff;}/* 获得现在日期 */public static function getDate():Number{return new Date();}/* 获得现在日期的月份 */public static function getMonth():Number{return new Date().getMonth() + 1;}public static function getFullYear():Number{return new Date().getFullYear();}/* 获得给定年的天数 */public static function getDaysOfYear(year:int):int {var startDate:Date = new Date(year, 0, 1);var endDate:Date = new Date(year+1, 0, 1);return (getDateDiff(startDate, endDate));}/* 获得给定年、月的天数 */public static function getDaysOfMonth(year:int, month:int):int{var startDate:Date = new Date(year, month, 1);var endDate:Date = new Date(year, month + 1, 1);return (getDateDiff(startDate, endDate));}//获得给定年 全年月份的天数public static function getMonthlyDayCounts(year:int):Array{var result:Array = [];var startDate:Date;var endDate:Date;var monthlyDayCount:int;for (var i:int = 0; i < 12; i++) {startDate = new Date(year, i, 1);endDate = new Date(year, i +1, 1);monthlyDayCount = getDateDiff(startDate, endDate); result.push(monthlyDayCount);}return result;}/* 比较两个日期大小 */public static function compare(date1:Date, date2:Date):int {if (Number(date1) < Number(date2)) {return -1}if (Number(date1) == Number(date2)) {return 0;}return 1;}//把date日期转化为Stringpublic static function convertToDateString(date:Date):String{var year:String = date.getFullYear().toString();var month:String = Number(date.getMonth() + 1) < 10 ?
