正则替换日期并格式化日期
转数字型：
ar ttDate = "2013年12月20日 14:20:20"
ttDate = ttDate.replace(/[^0-9]/mg, '').match(/.{8}/)
alert(ttDate)
结果：
20131220
转日期型：
var ttDate = "2013年12月20日 14:20:20"
ttDate = ttDate.match(/\d{4}.\d{1,2}.\d{1,2}/mg).toString()
ttDate = ttDate.replace(/[^0-9]/mg, '-')
alert(ttDate)
结果：2013-12-20
超级正则替换：
var ttDate = "2013年12月20日 14:20:20"
ttDate = ttDate.replace(/(\d{4}).(\d{1,2}).(\d{1,2}).+/mg, '$1-$2-$3')
alert(ttDate)
结果：
2013-12-20
在js里面怎么把时间类型转换成字符串方法一：
var temper="2009-6-28 15:23"
var dt = new Date(temper.replace(/-/,"/"))
alert(dt)
方法二：
function ConvertDateFromString(dateString) {
if (dateString) {
var arr1 = dateString.split(" ")
var sdate = arr1[0].split('-')
var date = new Date(sdate[0], sdate[1], sdate[2])
return date
}
}
获得一个月中的总天数：
function GetDayInMonth(day) {
var today = day
var year = today.getFullYear()
if (year <2000) year += 1900// Y2K fix
var month = today.getMonth()
var monarr = new Array(31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31)
if (((year % 4 == 0) &&(year % 100 != 0)) || (year % 400 == 0))
monarr[1] = 29
return monarr[month]
}
