Retrieve the initial element from a JSON object to identify errors, without being dependent on its specific key name

Utilizing AngularJS, my JSON call can result in various errors. Currently, I am handling it like this:

$scope.errors = object.data.form.ERRORS

or 

$scope.errors = object.data.system.ERRORS

However, in the future, 'form' or 'system' may change, so is there a way to access the errors without specifying them directly? Can I use something like object.data[1].ERRORS since errors are always present and located as the first element of the data?

This is how my data appears:

Object {member-participant: Object}
system: Object
ERRORS: "Email address already exists."

Answer №1

Have you tried iterating over the keys one by one?

$scope.errors = [];
for (var key in object.data) {
  if (object.data[key].ERRORS) {
    $scope.errors.push(object.data[key].ERRORS);
  }
}

To retrieve only the initial element, consider including a break statement.
