Regex matched the link with only one sub folder and requested content is JavaScript file-CodePudding

I'm writing a regex matching the links have only one sub folder with the requested content is JavaScript files with the length of 7 characters or more and no ? and & character in the back of the file.

Some specific examples:

(1) https://some.domain.example.tld/randomcharacter/randomfilename.js // match
(2) https://some.domain.example.tld/randomcharacter/randomfilename.js? // not match
(3) https://some.domain.example.tld/randomcharacter/randomfilename.js?a=b&c=d // not match
(4) https://some.domain.example.tld/subdir/public/lib/randomcharacter/randomfilename.js // not match

P/s: Please understand tld, randomcharacter and randomfilename are non-fixed.

This is my current regex:

/\/[a-zA-Z]{7,}\/[a-zA-Z]{7,}\.js$(?!(\?|&))/

It is correct for cases (1), (2) and (3). In the case (4), although there are a few other paths in front, it still matches and I don't want that!

How do I make it match exactly as I want it to be?

CodePudding user response：

For that, you need to include the first '//' to guarantee that you will have only 1 subfolder like:

\/\/[a-zA-Z.] \/[a-zA-Z]{7,}\/[a-zA-Z]{7,}\.js$

And you don't need the (?!(?|&)) after the end of the line '$' since there is nothing if the '$' matches
