rrule处理日历复发规则
rrule 是一个处理日历日期复发规则的 JavaScript 库。
rrule.js 支持在 iCalendar RFC 定义的复发规则，这是从优秀的 python-dateutil 库的 RRULE 模块的部分端口。最重要的是，它支持解析和序列化自然语言的复发规则。
使用示例：
// Create a rule:
var rule = new RRule({
freq: RRule.WEEKLY,
interval: 5,
byweekday: [RRule.MO, RRule.FR],
dtstart: new Date(2012, 1, 1, 10, 30),
until: new Date(2012, 12, 31)
});
// Get all occurrence dates (Date instances):
rule.all();
['Fri Feb 03 2012 10:30:00 GMT+0100 (CET)',
'Mon Mar 05 2012 10:30:00 GMT+0100 (CET)',
'Fri Mar 09 2012 10:30:00 GMT+0100 (CET)',
'Mon Apr 09 2012 10:30:00 GMT+0200 (CEST)',
/* … */]
// Get a slice:
rule.between(new Date(2012, 7, 1), new Date(2012, 8, 1))
['Mon Aug 27 2012 10:30:00 GMT+0200 (CEST)',
'Fri Aug 31 2012 10:30:00 GMT+0200 (CEST)']
// Get an iCalendar RRULE string representation:
// The output can be used with RRule.fromString().
rule.toString();
"FREQ=WEEKLY;DTSTART=20120201T093000Z;INTERVAL=5;UNTIL=20130130T230000Z;BYDAY=MO,FR"
// Get a human-friendly text representation:
// The output can be used with RRule.fromText().
rule.toText()
