Forum:Collapsible Table - CollapseButton text

Hello, I'm administrating a wiki on ko.wikia(korean language). And I noticed that, if I use this code /* Import Show-Hide JS */ importScriptPage('ShowHide/code.js', 'dev'); which allows to have Collapsible Table or Template:Hidden on the wiki, I get the collapsebutton Hide/Show as preformatted. I would like it to be in our language, like 보이기/숨기기, but I don't see how to enter my js code. If you could help me out?
