These properties can take input and give output.

  • format (enum or string)
  • filename (string)

invoke causes the file to be exported. Only works when enabled is set to TRUE.

enabled specifies whether exporting to HTML is enabled.

  • TRUE: The file is exported as specified by invoke.
  • FALSE: The file is not exported.

format specifies the file format to download.

filename specifies a name for the exported file. If blank, the file is returned as an HTML string or binary object in output and is not downloaded.

Output Properties

  • output (string)
