intereresante pregunta

Mira a ver si te sirve esto:

\documentclass[a4paper]{article}
\pdfobj stream {%
var d = new Date();
var d1 = util.scand("mm/dd/yy", "1/22/03");
if((d1.valueOf() - d.valueOf()) < 0){
app.alert("Document expired! Please get a new version
from Ki-Joo");
}
this.gotoNamedDest("page.2");
this.zoomType = zoomtype.fitP;
} \edef\ExpWarnObj{\the\pdflastobj}
\pdfrefobj\ExpWarnObj
\usepackage[pdfstartview={}]{hyperref}
\pdfcatalog{}
openaction
user {<< /S /JavaScript /JS \ExpWarnObj\space 0 R >>}
\begin{document}
test\newpage page 2
\end{document}


o esto:

\documentclass{article}
\usepackage[pdftex]{hyperref}
\usepackage[pdftex]{insdljs}
\newcommand\tugHello{Welcome to TUG 2001!}
\begin{insDLJS}[HelloWorld]{mydljs}{My Private DLJS}
function HelloWorld() { app.alert("\tugHello", 3); }
\end{insDLJS}
\begin{document}
\begin{Form} % needed for \PushButton
\section{Test of the \texttt{insDLJS} Package}
% use built in form button of hyperref
Push \PushButton[name=myButton,
onclick={HelloWorld();}]{Button}
\end{Form}
\end{document}
