As mentioned here, the old-school method to run another script is by using temporary files. Simple echo it into a file and then run it(and remove it optionally).


Here's the basic concept:

@echo off
echo //A JS Comment > TempJS.js
echo //Add your code>>TempJS.js

cscript //nologo //e:cscript.exe TempJS.js

del /f /s /q TempJS.js

But this would require lots of echo statements to create a relatively large JScript. Here's a better method by Aacini.

@echo off
setlocal

rem Get the number of the "<resource>" line
for /F "delims=:" %%a in ('findstr /N "<resource>" "%~F0"') do set "start=%%a"

rem Skip such number of lines and show the rest of this file
(for /F "usebackq skip=%start% delims=" %%a in ("%~F0") do echo %%a) > TempJS.js

cscript //nologo //e:cscript.txt TempJS.js
del /f /s /q TempJS.js

goto :EOF
