Window batch file - removing the directory from a file path

Question

I'm trying to search my code base for all jscript directories and then get a list of relative files within those directories using the following batch script...

@echo off

setlocal enableextensions enabledelayedexpansion

FOR /F "tokens=*" %%G IN ('DIR /B /AD /S jscripts') DO (
    CD %%G
    CD dev

    SET "currentDir=!cd!"
    IF NOT "!currentDir:~-1!"=="\" SET "currentDir=!currentDir!\"

    FOR /r %%F IN (*.js) DO (
        SET "relativePath=%%F"
        SET "relativePath=!relativePath:%currentDir%=!"

        ECHO !relativePath!
    )
)

It all works as expected until it gets to...

SET "relativePath=!relativePath:%currentDir%=!"

I can figure out what format I need to write this in to turn...

c:\dir\jscript\dev\file.js

into...

file.js

Please help!

Additional information

The directory setup is as follows

dir
    jscripts
        dev
            file.js
            file2.js
        live
            file.js
            file2.js


dir2
    jscripts
        dev
            file.js
            file2.js
        live
            file.js
            file2.js

I want find all jscripts directories, CD into them, get a list of all JS files relative to the dev directory

@echo off
setlocal enableextensions enabledelayedexpansion

rem Where to start
pushd "c:\wherever\global2_root\"

rem Search .....\dev directories
for /f "tokens=*" %%d in ('dir /ad /s /b ^| findstr /e "\\dev"') do (
    rem change to that directory
    pushd "%%~fd"
    echo Now in !cd!
    rem process files inside directory
    for %%f in (*.js) do (
        echo %%f
    )
    rem return to previous directory
    popd
)
rem return to initial directory
popd

rem cleanup 
endlocal

To extract the file name and extension from a variable containing a full path use %~nx0 as in

set G=c:\dir\jscript\file.js
echo %~nxG

Quoting the following from this answer to a similar question

%~I         - expands %I removing any surrounding quotes (")
%~fI        - expands %I to a fully qualified path name
%~dI        - expands %I to a drive letter only
%~pI        - expands %I to a path only
%~nI        - expands %I to a file name only
%~xI        - expands %I to a file extension only
%~sI        - expanded path contains short names only
%~aI        - expands %I to file attributes of file
%~tI        - expands %I to date/time of file
%~zI        - expands %I to size of file

The modifiers can be combined to get compound results:
%~dpI       - expands %I to a drive letter and path only
%~nxI       - expands %I to a file name and extension only
%~fsI       - expands %I to a full path name with short names only

This is a copy paste from the "for /?" command on the prompt. Hope it helps.
