Question

我说,我不是很新,经常说几句,但我迄今未能为我的问题找到适当的表述:

I want to check a string that a user types into a textfield. The string has to consist of one ore more terms that are separated with a semicolon.

实际上有两种术语:

All terms have to be concluded with a semicolon.

有效投入是:1-4;5,6,7;9-11;或1,3;4-6;8,9,10;

我尝试了这么多的改动,但迄今无法找到解决办法。我的问题是,这种投入可能包含任何几个术语。我试图用<代码>OR的操作器和“lookahead”分别解决这一问题,但没有成功。

Any help would be very appreciated.

Thanks much, enne

Answer 1

该机构应做以下需要:

/^(?:[0-9]+-[0-9]+;|[0-9]+(?:,[0-9]+)*;)+$/

Answer 2

EDITED: The first question looked the semicolons were separators, now it shows them as terminators.

这里的顺序为一个或多个术语,terminated/em>,由半殖民地标明,每一术语要么是编号,要么是编号,要么是编号,要么是序号,要么是编号:

/^(d+(-d+|(,d+)*)?;)+$/

With non-capturing groups

/^(?:d+(?:-d+|(?:,d+)*)?;)+$/

Answer 3

my take..

^(:d+--d(?: ; :d- >:d?:[,+>+”+)+
