我們?cè)趯?shí)際工作當(dāng)中經(jīng)常會(huì)遇到很多js驗(yàn)證日期正則表達(dá)式的項(xiàng)目,而很多人不知道改如何使用正則表達(dá)式來(lái)做javascript日期驗(yàn)證正則表達(dá)式，下面我就給大家提供一個(gè)本人收集的較全js驗(yàn)證日期正則表達(dá)式。

日期時(shí)間腳本庫(kù)方法列表

Date.prototype.isLeapYear 判斷閏年
Date.prototype.Format 日期格式化
Date.prototype.DateAdd 日期計(jì)算
Date.prototype.DateDiff 比較日期差
Date.prototype.toString 日期轉(zhuǎn)字符串
Date.prototype.toArray 日期分割為數(shù)組
Date.prototype.DatePart 取日期的部分信息
Date.prototype.MaxDayOfDate 取日期所在月的大天數(shù)
Date.prototype.WeekNumOfYear 判斷日期所在年的第幾周
StringToDate 字符串轉(zhuǎn)日期型
IsValidDate 驗(yàn)證日期有效性
CheckDateTime 完整日期時(shí)間檢查
daysBetween 日期天數(shù)差
