Unable return sucessful validate when using signature pad

Question

I need to verify that the user signed the form. We are using a signature pad to capture the electronic signature. And then using the code below in a button to validate. If the signature is left blank I do get the message that the "Signature is not valid: signature is blank". But if I complete the signature field I do not get anything back.
var f = event.target.getField("form1[0].S1[0].SignatureField1[0]");
// Validate the signature field:
var status = f.signatureValidate();
/* signatureValidate method returns one of the following integer validity status values:
-1: not a signature field
0: signature is blank
1: unknown status
2: signature is invalid
3: signature is valid, identity of signer could not be verified
4: signature and identity of signer are both valid
// Obtain the signature information
var sigInfo = f.signatureInfo();
if (status < 3)
var msg = "Signature is not valid: " + sigInfo.statusText;
else
var msg = "Signature is valid: " + sigInfo.statusText;
// Display the status message:
app.alert(msg);;
I have also tried just returning the status using
app.alert("Signature status: " + status);
When I leave the signature blank I get "Signature status: 0"
When I fill in the signature, I don't get the message box.
Is there another command for validating with a signature pad.
Thanks,

Answer 1

try using the status property. This is currently working for me.
var oState = event.target.getField(("form1[0].S1[0].SignatureField1[0]").signatureInfo().status;
