Javascript-Anwendung in Latex

Ich möchte wissen, ob es möglich ist, einem Latex-Dokument eine mit Javascript erstellte interaktive App hinzuzufügen.

Ich möchte einige der Javascripts hinzufügen, die erscheinenHier.

Wie das Eine:

Ich kann das .js-Dokument haben, daher möchte ich wissen, wie ich eine .js-Datei an Latex anhängen kann.

Irgendeine Idee? Irgendeine Hilfe?

Antwort1

Dies portiert das Kartenmischbeispiel unter Verwendung von PDF Layers (Paket ocgx2) und JavaScript nach LaTeX und PDF. Zur Anzeige ist Acrobat Reader erforderlich.

Aktualisieren: Erweitertes Beispiel mit Diagramm, das die Königs-Karo-Position gegenüber der Gewehranzahl aufzeichnet.

Warnung:pdflatexAufgrund der großen Anzahl von OCGs (ca. 21 KB), die erstellt werden, dauert es etwa 2 Stunden, den Code zweimal zu kompilieren. Darüber hinaus muss für pdflatexeine erfolgreiche Ausführung main_memorydas Format vergrößert oder lualatexstattdessen verwendet werden. Das (ursprüngliche) Beispiel ohne das Diagramm wird viel schneller kompiliert (zweite Codebox).
