这取决于您希望触发JavaScript代码的事件类型.

It depends on the type of event you want your JavaScript code to be triggered at.

例如，要定义将在打开文档后立即执行的动作，请使用PdfDocument#getCatalog().setOpenAction.

For instance, to define an action that would be executed as soon as the document is opened, use PdfDocument#getCatalog().setOpenAction.

打开文档时打开打印对话框的示例:

Example for opening a print dialog when the document is opened:

pdfDocument.getCatalog().setOpenAction(PdfAction.createJavaScript("this.print(true);"));
