Dear Eric,

It works perfectly in detail.pl page. 
Thank you very much.

Regards,
Ketut

So I assumed ".pdf" would appear somewhere in the link. You can use this updated code to hide any "online resources" links even once that look like the "opac-retrieve-file" links: https://gist.github.com/phette23/f4595ae6b8bddcf8d55cd12cc378253a

And pasted here:

// run 1) on opac-detail pages & 2) if no user is signed in
if (!!location.pathname.match('/cgi-bin/koha/opac-detail.pl') && !$('.loggedinusername').length) {
    // replace 856$u links with a link to login instead
    // this would need to be tweaked if there are multiple URLs per record
    $('.results_summary.online_resources a')
        .replaceWith('<a href="/cgi-bin/koha/opac-user.pl">login to view PDF</a>')
}Again, though, this is somewhat illusory; people can still access these PDFs without logging in if they really want to and have some minimal technical skills. So if the PDFs are quite sensitive you would need another approach.
