I have a json object as a response from the server . I want to acces to Base64Signature object , i don't know how because some objects names are not accessible such as @WhichDocument and sc.ExtendedSignatureObject . This is the response from the server
   { 'sc.SignatureObjects':
   { 'sc.ExtendedSignatureObject': { '@WhichDocument': 'AISDoc1', Base64Signature: [Object] } } }
