我如何以角度方式遍历表单字段？

Question

I've got a form containing many fields, which I need to process one-by-one using some function. You can assume I need to concatenate all fields' values into a string.

The form uses ng-model.

<div ng-form="form" ng-submit="submit()" novalidate>
    <input ng-model="ctrl.firstName" required="true">
    <input ng-model="ctrl.lastName" required="true">
    <!-- 30+ more inputs -->
</div>

I would like to do this angular-way, without iterating over the DOM.

You could do something like this on angular submit function:

for (var field in $scope.ctrl) {
    if ($scope.ctrl.hasOwnProperty(field)) {
        // do stuff
        $scope.ctrl[field] ...
    }
}
