你有一个错误正则表达式：

删除正则表达式的最后部分中的那些双方括号;）



这应该有效： ^ [0-9] {4} - [0-9] {1} - [0-9a-zA-Z] *

You have an error in you Regex:
Remove those double square brackets in the last part of your Regex ;)

This should work: ^[0-9]{4}-[0-9]{1}-[0-9a-zA-Z]*

是否要将整个字符串限制为最多15个字符。或者最后一部分可以是0-15个字符？或者最后一部分的长度超过15个字符？

Do you want to limit the whole string to max 15 chars. or the last part can be 0-15 chars? or has the last part to be longer longer than 15 chars?
