在 Ruby 中添加 JavaScript

Aspose.PDF - 添加 JavaScript

要在 PDF 文档中使用 Aspose.PDF Java for Ruby 添加 JavaScript，只需调用 AddJavaScript 模块。

Ruby 代码

# The path to the documents directory.

data_dir = File.dirname(File.dirname(File.dirname(File.dirname(__FILE__)))) + '/data/'

# Open a pdf document.

doc = Rjb::import('com.aspose.pdf.Document').new(data_dir + "input1.pdf")

# Adding JavaScript at Document Level

# Instantiate JavascriptAction with desried JavaScript statement

javaScript = Rjb::import('com.aspose.pdf.JavascriptAction').new("this.print({bUI:true,bSilent:false,bShrinkToFit:true});");

# Assign JavascriptAction object to desired action of Document

doc.setOpenAction(javaScript)

# Adding JavaScript at Page Level

doc.getPages().get_Item(2).getActions().setOnOpen(Rjb::import('com.aspose.pdf.JavascriptAction').new("app.alert('page 2 is opened')"))

doc.getPages().get_Item(2).getActions().setOnClose(Rjb::import('com.aspose.pdf.JavascriptAction').new("app.alert('page 2 is closed')"))

# Save PDF Document

doc.save(data_dir + "JavaScript-Added.pdf")

puts "Added JavaScript Successfully, please check the output file."
