While (like it can be seen in the EDIT) the forms I found where not affected with JS. Other forms from my uni where.

For example I found following:

`/JS (if \(this.getField\("inst1"\).value == "bitte auswählen"\){\r\nthis.getField\("Hinweis"\).display = 2\r\n} else\r\n{\r\nthis.getField\("Hinweis"\).display = 1\r\n}\r\n)$ /S /JavaScript`

This (in the given PDF) causes a "notice" overlapped on top of other form fields to disappear once the first multiple choice field was selected.

So if you try to fill it out without JS some form fields are not visible (but selectable by tab). Luckily it's not included in prints.
