Adding a File to a PDF using Javascript

[patrickpai]

Good day everyone

I was wondering if there's a way to know via javascript, if at least one file is attached to said PDF?

Im prsently using this code to let someone attch a file:

var myDoc = event.target;
var sFile = "myFile"
myDoc.importDataObject(sFile);

app.execMenuItem("ShowHideFileAttachment");

But after that, how can i keep track of this? I could use right now a variable to tell me its been added... but what if a user deletes the attachement?? can i track that? if so, i could update said variable maybe??

Any ideas??? thx so much for the help again 🙂

Yes, here's a link to the JS reference entry

Sounds good, i will take a look at the reference link just to help me understand better what is going on.

Thx for the input. Would you be able to capture via javascript, if the person did press the remove attachment button???

No, There are no JavaScript events associated with actions taken at the application level.

Hi,

Unless I'm mistaken, this only works if the attachment has been imported manually... not with the importDataObject method!

the importDataObject method does add to the standard data objects. It's the FileAttachment annot that doesn't add to the dataObjects (as try67 pointed out).

You can check the length of the dataObjects array, but this only works for actual Attachments. If they used the Attach File commenting tool, that won't appear there. To detect that you would need to scan the entire annotations array of the file, checking if any of them are of the "FileAttachment" type.
