Confirming digital signature: urgent help needed

[Former Community Member]

Hi!

I am working on a form and I need to check if the form is digitally signed, before I hit the submit or save button.



I tried the following JavaScript code but it does not work:

if(SignatureButton.rawValue == null)// the form has not been signed

{

app.alert("Please digitally sign the form before submission");

exit;

}



Any help would be greatly appreciated. Thanks a bunch in advance.
