Lyx 使用 JavaScript 生成的 PDF 遇到 NotAllowedError

我正在尝试生成一个 pdf 文件，并使用此代码打开另一个 pdf 文件

\usepackage[pdftex]{insdljs}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Main Script
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{insDLJS}{dljs}{Document Javascript}

doesitopen = app.trustedFunction (function() {
    var reffile1,openf;
    try {
        app.alert("trying c:/temp/existing.pdf",3);
        console.println('here');
        app.beginPriv();
            app.openDoc("/c/temp/existing.pdf");
        app.endPriv();
        openf = 1;
    }
    finally {
        e = null;
    }
    app.alert("diditopen",3);

});

doesitopen();
\end{insDLJS}

这是我的 Lyx 文件 - 它非常普通 -

我的问题是 Adob​​e 拒绝执行我的代码，尽管已经使用并app.trustedFunction标记了我的代码app.beginPriv()app.endPriv()

当我运行 Adob​​e Reader XI 时，JavaScript 控制台中出现此错误：

Acrobat EScript 内置函数版本 11.0 Acrobat SOAP 11.0

NotAllowedError：安全设置阻止访问此属性或方法。App.trustedFunction:3:Document-Level:01 文档 Javascript

NotAllowedError：安全设置阻止访问此属性或方法。App.trustedFunction:1:Document-Level:01 文档 Javascript

NotAllowedError：安全设置阻止访问此属性或方法。App.trustedFunction:1:Document-Level:01 文档 Javascript

答案1

根据Acrobat 的 JavaScript API 参考，该方法app.trustedFunction受到安全限制，仅允许在批处理、控制台和应用程序初始化事件中使用，即不能在文档级 JavaScript 中使用。

另一方面，app.openDoc()不需要在受信任的环境中被调用。

所以，

\begin{insDLJS}{dljs}{Document Javascript}
  app.openDoc('c:/temp/existing.pdf');
\end{insDLJS}

应该已经可以工作了。
