How can AngularJS handle multiple views sharing the same controller and ensure that the controller is executed only once?

Currently, I am facing a situation where I have two separate views that I would like to control within a single controller.

The issue is, the controller is being executed twice. Is there a way to link multiple views to the same controller without the controller running more than once?

I understand that creating a factory to share $scope data might be necessary, but the aim is to avoid fetching the data repetitively.

.state('cloud', {
    url: '/cloud',
    views: { 
        'main': { templateUrl: 'main.html', controller: 'cloud' },
        'second': { templateUrl: 'second.html', controller: 'cloud' }
    }
})

Answer №1

There is a situation where the controller runs twice because in the "cloud" state, two views are defined with the same controller.

As a result, when both views are loaded, the controller is called twice.

To ensure that the controller is only called once, it is necessary to define separate controllers for each view.
