My requirement is to show warning message before signing the document without customizing the PDF.

For this I am creating custom menu to execute below action in sequence:

  1. Execute JavaScript to show alert 
  2. And then pop up digital signature

 

Below is the Javascript:

 

 

 

var DoMyMenuItem = app.trustedFunction(function(cItemName) {
    app.beginPriv();
    app.execMenuItem(cItemName);
    app.endPriv();
});

function CallMenu() {
    try {
        app.execMenuItem("FillSignApp");
        //DoMyMenuItem("Signatures");
    } catch (e) {
        app.alert("Error: " + e);
    }
}
app.addMenuItem({ cName: "My Action Menu", cParent: "Help", cExec: "CallMenu(); " });

 

 

I am getting this error "Error: InvalidArgsError: Invalid arguments." on runtime. 
 
Is there anywhere I can show warning message to user before signing document and Is there a way to call Digital Signature using JavaScript execMenuItem function?

Where are you trying to run these scripts from?

 

Another text field ? or as an javascript action that executes when the signer clicks on the signature field?

I have created "Config.js" and kept inside "C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\Javascripts"

You are correct, this script is not working. I want to know what need to be pass inside app.execMenuItem method to open signature popup.

 

For example, try replacing below line in above code.

app.execMenuItem("ReadingMode");

 

Note: You need to close the Adobe and open again.  After then open any pdf document and click on new menu "My Action Menu" under help.

There's no menu item from signing a Signature field. It can be done using the signatureSign method of the Field object. Read the documentation carefully before using it.
