I need to have a Regex for matching a single (or greater) non- blank space character (would allow all special characters such as !,' etc...). Would
var filter = /\S+/;
be sufficient? This seems to work for 1 or greater.
Would:
var filter = /\S+/{3,};
be sufficient for 3 or more of the non-same characters (like "def", "a!c", "dA!!f", but not "some bird"?

Currently I have a textbox that accepts only Alphabet, hyphens(-), space and apostrophes('). Now I would like to add numeric values as well to it. Currently I am using the Regex as below:
/^[a-zA-ZÀ-ÖØ-öø-ÿ' -]+$/
How would I achieve adding numerics as well to the above?
To allow numbers, simply add 0-9 in your regex, like so:
/^[0-9a-zA-ZÀ-ÖØ-öø-ÿ' -]+$/

Currently I'm using regex=/^(\w+\s?)*\s*$/, it's working fine for extra space, but failing for special characters.
Expectation:
regex.test('abcd ghh') => false
regex.test('abcd*') => true
You will need the last regex pattern of this solution.
[^\s]([ ]{2,})[^\s]

I've created regex to parse football match score:
(0|[1-9]\d*\s)(:)(\s0|[1-9]\d*)
When I try:
let scoreRegex = new RegExp('(0|[1-9]\d*\s)(:)(\s0|[1-9]\d*)')
scoreRegex.exec('Team One 5 : 0 Team Two')
I get null instead of expected 3 groups. Any online parser out there validates my regex and matches the input string.

I have a very simple form with this regex pattern set on my first/last name fields ng-pattern="/^[a-zA-z]{2,30}$/" and both fields accept this value as being valid e.g. Tester\^*&^%. The first/last name should only accept alpha character a-zA-Z with a minimum of 2 characters and a max of 30.
Here is the wrong thing.
^[a-zA-z]{2,30}$
^
|
It would match \^ symbols because these symbols are comes under the range from A to z.
Modified regex.
^[a-zA-Z]{2,30}$
