javascript regex iso datetime [英] javascript regex iso datetime

问题描述

有没有人有一个很好的regex模式匹配iso数据时间？

ie：2010-06-15T00：00：00

解决方案

对于严格的，完整的日期时间，包括毫秒，每 W3C的规范 。：

  //  -  - 完整的精度：
 / \d {4}  -  [01] \d- [0-3] \dT [0-2] \d：[0-5] \d：[ 0-5] \d\.\d +（[+  - ] [0-2] \d：[0-5] \d | Z）/ 
 
 //  -  - 没有毫秒：
 / \d {4}  -  [01] \d- [0-3] \dT [0-2] \d：[0-5] \d：[ 0-5] \d（[+  - ] [0-2] \d：[0-5] \d | Z）/ 
 
 //  - 无秒数：
 / \d {4}  -  [01] \d- [0-3] \dT [0-2] \d：[0-5] \d（[+  - ] [0- 2] \d：[0-5] \d | Z）/ 
 
 //  - 把它们放在一起：
 /（\d {4}  -  [01 ] \d- [0-3] \dT [0-2] \d：[0-5] \d：[0-5] \d\.\d +（[+  - ] [0-2] \d：[0-5] \d | Z））|（\d {4}  -  [01] \d- [0-3] \\ dT [0-2] \d：[0-5] \d：[0-5] \d（[+  - ] [0-2] \d：[0-5] \d | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |]]]]]]]]]]]]]]]]]]]]]] [0-2] \d：[0-5] \d | Z））/ 
  

。

实际的 ISO 8601：2004（E）文档允许的其他变体：

  / ******************** ************************ 
 **无时区变量：
 * / 
 //  - 完成精度：
 / \d {4}  -  [01] \d- [0-3] \dT [0-2] \d：[0-5] \d：[0 -5] \d\.\d + / 
 
 //  - 无毫秒：
 / \d {4}  -  [01] \d- [0- 3] \dT [0-2] \d：[0-5] \d：[0-5] \d / 
 
 //  - 无秒数：
 / \d {4}  -  [01] \d- [0-3] \dT [0-2] \d：[0-5] \d / 
 
 //  - 把它们放在一起：
 /（\d {4}  -  [01] \d- [0-3] \dT [0-2] \d：[0-5 ] \d：[0-5] \d\.\d +）|（\d {4}  -  [01] \d- [0-3] \dT [0-2] \\ \\d ：[0-5] \d：[0-5] \d）|（\d {4}  -  [01] \d- [0-3] \dT [0-2] \ d：[0-5] \d）/ 
  

警告：这一切都会变得很快，它仍然允许某些废话，如第十四个月。
此外，ISO 8601：2004（E）允许其他几种变体。

2010-06-15T00：00：00不合法，因为没有时间-zone name。

does anyone have a good regex pattern for matching iso datetimes?

ie: 2010-06-15T00:00:00

解决方案

For the strict, full datetime, including milliseconds, per the W3C's take on the spec.:

//-- Complete precision:
/\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d:[0-5]\d\.\d+([+-][0-2]\d:[0-5]\d|Z)/

//-- No milliseconds:
/\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d:[0-5]\d([+-][0-2]\d:[0-5]\d|Z)/

//-- No Seconds:
/\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d([+-][0-2]\d:[0-5]\d|Z)/

//-- Putting it all together:
/(\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d:[0-5]\d\.\d+([+-][0-2]\d:[0-5]\d|Z))|(\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d:[0-5]\d([+-][0-2]\d:[0-5]\d|Z))|(\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d([+-][0-2]\d:[0-5]\d|Z))/

.
Additional variations allowed by the actual ISO 8601:2004(E) doc:

/********************************************
**    No time-zone varients:
*/
//-- Complete precision:
/\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d:[0-5]\d\.\d+/

//-- No milliseconds:
/\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d:[0-5]\d/

//-- No Seconds:
/\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d/

//-- Putting it all together:
/(\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d:[0-5]\d\.\d+)|(\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d:[0-5]\d)|(\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d)/

WARNING: This all gets messy fast, and it still allows certain nonsense such as a 14th month. Additionally, ISO 8601:2004(E) allows a several other variants.

.
"2010-06-15T00:00:00" isn't legal, because it doesn't have the time-zone designation.
