I am trying to implement a MyCode which contains Javascript but it shows empty box in the post. How to enable javascript in a MyCode?

Alternatively; would you suggest a free advertisement plugin which support JavaScript ad codes from different ad networks?

I am using MyBB 1.8.6 version.

if you are referring to codes like this then
basically the code with js file link should be added to headerinclude template
and the function part in any other template where you need it
