getPageNthWord to include hyphens

Working on a POC to look for pattern e.g 12345-1234 and then create a hyperlink on it using javascript.

My question is how to make 'getPageNthWord' function to include '-' while splitting words. As of now, when '-' is found, the word is cut as '12345-' and '1234'.

I want as single word without any split

Any kind of help is appreciated.

Thanks in advance.
