我试图做到以下几点,只是允许在我的盒子中注入新的活力,但这样做是巨大的。 是否有其他东西可以补充防止增加零件?

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。

Code:

^([1-9][0-9]+|[1-9])$

例:

测试:

0
10
01
11
00
1
100
^(d{2}[1-9])$

matches with: from 001 to 999 example 001 099 999

does not match 000 01 0
