Is it possible to utilize a factory function with ng-submit?

Question

Is it possible to utilize a factory function with ng-submit?

I am working with a factory that has the function setRoot() defined as shown below, and I need to implement it in my controller.

$scope.testSubmit = testFactory.setRoot();

However, when I open the HTML file containing ng-submit="testSubmit()", the factory function is executed before anything is inputted into the form. How can I properly utilize the factory function within ng-submit?

.factory('testFactory', function($rootScope){
        return {           
            setRoot: function(){
                $rootScope.root = 'inside testFactory';
            }
        }
    })

Answer №1

When implementing your function, it's important to take the right approach. Instead of calling it immediately, follow this method:

$scope.testFactory = testFactory;

For your ng-submit, use the following:

ng-submit="testFactory.setRoot()"

This step will first connect the factory to the $scope, enabling access to its functions like .setRoot. Remember, you should only call the function within the actual ng-submit, not when connecting the factory to the $scope.

Keep in mind that adding () after a function indicates immediate execution. To bind a function for later use, assign it as

$scope.testFactory = testFactory.setRoot

, and then directly use ng-submit="testFactory()".

However, one major issue is attempting to set $rootScope inside a factory, which won't work. Similarly, setting $scope from within a factory is not feasible. In such cases, return a value from the factory and bind it to either $rootScope or $scope in your controller.
