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
参考代码如下:
var s='2017-05-24 12:33:22''定义日期字符串s=s.replace(/ \d+(:\d+){2}/,'')'正则过滤后面的时间,只显示年月日
alert(s) '弹出日期
效果图如下:
定义和用法
replace() 方法用于在字符串中用一些字符替换另一些字符,或替换一个与正则表达式匹配的子串。
返回值
一个新的字符串,是用 replacement 替换了 regexp 的第一次匹配或所有匹配之后得到的。
