"The controller's $scope isn't being updated within the DIV following a routing change

My website contains ng-view partials that change based on routing updates in $routeProvider.

anmSite.config(function($routeProvider, $locationProvider){
$locationProvider.html5Mode(true);

$routeProvider
    //Home page route
    .when("/", {
        templateUrl: "templates/main.html",
        controller: "imageController",
        title: "Passionate about perfection",
    })
    //About page route
    .when("/me", {
        templateUrl: "templates/me.html",
        controller: "imageController",
        title: "About Me",
    })
    //Design page route
    .when("/design", {
        templateUrl: "templates/design.html",
        controller: "imageController",
        title: "Site Design",
    })
    //Projects page route
    .when("/projects", {
        templateUrl: "templates/projects.html",
        controller: "imageController",
        title: "Projects",
    })
    //Photos page route
    .when("/photos", {
        templateUrl: "templates/photos.html",
        controller: "imageController",
        title: "Photos",
    })
    //Default route to /
    .otherwise({
        redirectTo: "/"
    });
});

All routes use the 'imageController', which updates the $scope based on $location.path().

anmSite.controller("imageController", function($scope, $location){

var image = {
    class: "",
    text: ""
};

var imageClass, imageText = "";
switch($location.path()){
    case "/me":
        image.class = "me";
        image.text = "Me";
        break;
    case "/design":
        image.class = "design";
        image.text = "Design";
        break;
    case "/projects":
        image.class = "projects";
        image.text = "Projects";
        break;
    case "/photos":
        image.class = "photos";
        image.text = "Photos";
        break;
    default:
        image.class = "surfer";
        image.text = "Surfer";
        break;
}
$scope.image = {
    class: image.class,
    text: image.text
};

});

In index.html, I have added a div above the ng-view section, containing 2 $scope variables that need to be updated for each route.

<div ng-controller="imageController">
    <div class="image-container {{ image.class }}">
        <h1>{{ image.text }}</h1>
    </div>
</div>

<div class="ng-view"></div>

The initial page load works fine, but the ng-controller div does not update with each route change, even though the $scope variables are updated (confirmed with console.log). Is there a way to refresh the ng-controller view? Should I use other Directives? Any suggestions would be appreciated.

Answer №1

If you're facing issues, try adjusting your code within the "ng-view" element to align with Angular's guidelines.

According to Angular documentation, ngView is a directive that works alongside the $route service by displaying the template of the current route in the main layout (index.html) file. Whenever there is a change in the current route, the view displayed also changes based on the $route service configuration.

You can structure it like this:

<div class="ng-view">

<div ng-controller="imageController">
<div class="image-container {{ image.class }}">
    <h1>{{ image.text }}</h1>
</div>
</div>
</div>

Additional note - Based on the discussion in the comments below, the successful approach involves creating a directive and utilizing the link function to monitor $routechange events such as $routechangestart. This ensures that your scope is updated every time there's a route change.

I hope this clarifies things for you!
