It is possible to use the class Core.Annotations.Forms.EmbeddedJS to define or overwrite functions from Adobe Document Javascripts? If possible, is there an example of this?

Hello l.l.serrala,

Welcome to the PDFTron Community Forum.

You can access the Adobe scope (ADBE) within a document, using:

Annotations.Forms.EmbeddedJS.update(scope => {
  // Scope represents the window scope that embedded javascript runs within
  // Define the ADBE namespace so that older PDFs will find it
  scope.ADBE = {};
});

Thank you for your answer, but I’ve seen this example / guide before. I ask because I don’t understand how to use it to define or override a function from Adobe Document Javascripts. We are using some PDFs with the same document javascript functions, now there is a change for a function so we would like to try declaring this function directly in the viewer instead of having to change a lot of PDFs.

Hello l.l.serrala,

Would you be able to provide a sample document for me to create a specialized code snippet for an example?

In general, you would override a function in the EmbeddedJS like this:

    Annotations.Forms.EmbeddedJS.update((scope) => {
     // Where .Test is a custom function defined in the PDF
      scope.Test = () => {
        console.log("Test function")
      }
    });
