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

这是一个Unix时间戳,在Javascript中,用毫秒表示Unix时间戳,所以此数要乘上1000(1秒=1000毫秒)

字符串乘以数字结果是数字类型,所以可以直接用Date对象生成日期了

alert(new Date("1379433600"*1000))//Wed Sep 18 2013 00:00:00 GMT+0800 (中国标准时间)剩下有关日期处理的问题,可以直接通过Date对象的相应方法进行处理
