Here is some code that will allow you to check the signature field:
// check to see if Claimant signature field is signed.
var oSOM = claimsign.somExpression; // Returns the full SOM expression i.e. xfa[0].form[0].form1[0]...
var truncSOM = oSOM.substring(15); // Truncating 'xfa[0].form[0]' from SOM to get acroforms name of the field.
var oState = event.target.getField(truncSOM).signatureValidate(); // Get the current field's signed state
In this case the signature field is called claimsign. After running this code the variable oState will conatin a value ....if it is 0 then the field is not signed. So you can add code like this:
if (oState == 0 ) {
// signature field is not signed
app.alert("You must sign the form before submitting")
} else {
//The signature field is signed
go through your submission process code
}
Hope that helps
