Save as the same name (button)

The reason there is an "external" JavaScript solution is because the "doc.saveAs()" function can only be run silently if it is executed from a privileged context. To do this from a script inside a PDF would be a security violation because it would be allowing a PDF, which could come from anywhere, to perform an operation on the user's system without thier knowledge.

However, there is a way to do this. If the document is established as trusted by the user, then scripts inside the PDF can perform privileged operations.

One way to establish trust is to certify the PDF with a digital signature. If the user has the public key for the signature on thier system and it is registered with Acrobat, then the PDF is considered trusted.

Acrobat 9 has another method called a trusted folder, but it's new and I haven't done much testing on it so I can't vouch for it.

Der Thomp,

thank you for your quick answer.
Because of this im testing to external option.

i´ve an exam.js with only this code:

// SaveAs Function
var mySaveDoc = app.trustedFunction(function(doc) {

app.beginPriv();
var myPath = app.getPath("user", "documents") + "test123.pdf";
doc.saveAs(myPath);
app.endPriv();

});


on my button in my pdf is this script:
this.mySaveDoc(event.target);


But if i push the button, my debugger responses:

TypeError: doc.saveAs is not a function
7:Folder-Level:App:exam.js

Can you please help me again. I dont know why this happens.

Best wishes
Heinz Eckert

Did you create the form in Acrobat or LiveCycle Designer?

I created all in Acrobat

The code in your button should be:

mySaveDoc(this);

Oh, thank you very much!
Im such an idiot :)

But, is there an option to save the file in the current used folder?
My file would be opened in any folder on the lokal pc. Can i save it in this folder, however i dont know in which folder the user opened the pdf?

I just want to override the existing file.

If you just want to overwrite the existing file, do this in your function:

doc.saveAs(doc.path);

thank you, that was a big help!
