I have the following regex that allows any number (x), or comma separated numbers (x,x), or any range (x-x) for an input on my page:
^d+(?:(?:s*-s*d+)?|(?:s*,s*d+)*)$
This works perfectly but I have a new requirement. I need to allow the user to label what they are defining and allow that if it's valid. For example, they can say: Buildings: 1000-1010 or Buildings: 1001,1002.
Buildings: must be in the beginning of the string followed a colon followed by the rest. If they don't specify I won't know what they are saying.
Currently Buildings is the only label they can define, but I know more will be coming so I would also like to be able to specify that, if possible. But hopefully I can figure it out if I figure out how to allow one:
let input = 'Buildings: 1000-1001';
/^d+(?:(?:s*-s*d+)?|(?:s*,s*d+)*s*,?)$/.test(input); // should be ok
input = 'Buildings: 1000';
/^d+(?:(?:s*-s*d+)?|(?:s*,s*d+)*s*,?)$/.test(input); // should be ok
input = 'Buildings: 1000,2002';
/^d+(?:(?:s*-s*d+)?|(?:s*,s*d+)*s*,?)$/.test(input); // should be ok
For future, say I have an array of labels:
const categories: ['Buildings', 'Cars', 'Houses'];
To loop over this list and run the test and include the variable's value in the regex. Is it possible?
Are you supposed to hardcode the text? I started trying that but I kept getting errors.
Thank you
