这将允许10个但不是1个,只允许由数人构成的数字,即没有时间或标记......但也没有附加标志、科学标志等。
^[1-9][0-9]*$
略有改动:
/d*[1-9]d*/
这将使零开始。
如果你不关心诸如<代码>07<>>>>>>>>/代码”等负面和隐性编号,这将:
/[1-9]d*/
为了更强有力的解决办法,我建议,如果符合你的标准,将相应的扼杀转换为愤怒和检查。
^(0*[1-9][0-9]*)$
这将使像007这样的“沉默”数字成为可能,但不会有0或000或空洞。
注:<条码>d条码>也与诸如<条码>/条码>等其他特性组的数。 见https://stackoverflow.com/a/16621778/880990>。 效率低于[0-9]。
^(d{2}[1-9])$
matches with: from 001 to 999 example 001 099 999
does not match 000 01 0
