![]() So, it might be a good idea to keep this hint as an "educational" example, but definitely not use it. And I don't even talk about (fillable) forms.Īnd one might think about it, that many really high-profile organizations, where problems security-wise would really give them a hard time (let's talk about tax authorities) use and distribute documents with JavaScript built in. More and more even simple documents use some JavaScript for additional functionality, be it navigation, be it for displaying contents. So, as "functional" the hint is, it is indeed a hint which will cause more problems than it will prevent. Potentially dangerous actions do require an additional action of some kind by the user (such as confirming a dialog box, selecting a file name, doing an additional installation, etc.). ![]() And, what is more important, access "behind the user's back" is not possible ("behind the user's back" means that the user does not notice anything). File system access is rather limited for reading, and extremely limited for writing. Acrobat JavaScript essentially runs in its own sandbox, and has only very limited access to the "external world". However, disabling Acrobat JavaScript because of "security" reasons is rather a weak argument.īecause of the way Acrobat has JavaScript implemented, particularly in Acrobat 7, none of the "reasons" why JavaScript should be disabled in browsers are valid. Of course, it is the user's good right to disable JavaScript in Acrobat.
