refresh the route without having to reload the controller

I have a specific detail page dedicated to each car ID, on this page, there is a gallery of photos fetched from the service. Users can click on these photos to view them in full size.

I am looking to create a shareable URL that includes the selected car, photos, and highlights the chosen photo by default.

Reloading the entire page is unnecessary since I already have the car information loaded. My goal is to only retrieve details for the selected photo when a user clicks on one of the thumbnails.

I hope this explanation clarifies the issue at hand. Below is the code snippet:

function CarsController($scope, $routeParams, $location, CarsFactory, PhotosFactory) {

    CarsFactory.get({id: $routeParams.id}).$promise.then(function(car) {
        console.log(car);
    });

    PhotosFactory.query({carId: car.id}).$promise.then(function(photos) {

        /*
            Display all photos with carId = car.id
            allowing users to click and view a specific image ($scope.selectPhoto)
        */
    });

    $scope.selectPhoto = function(photoId) {

        /*
            When any photo is clicked, update the URL to /cars/{car.id}/{photoId}
            Attempted using $location.search('photoId', photoId); however, it adds a query string instead of changing the URL segment.
        */
    }

    if ($routeParams.photoId) {
        PhotosFactory.get({id: $routeParams.photoId}).$promise.then(function(photo) {
            console.log('Default photo: ' + photo);
        });
    }
}

Thank you.

Answer №1

One way to simplify the process is to create a link within your webpage that only appears when an image is clicked:

<img ng-click="showDiv = !showDiv" src="..." />

<div ng-show="showDiv" >
    <a href="/url_part1/{value1}/url_part2/{value2}">link</a>
</div>

Answer №2

If you need to modify a URL path (also known as a "segment"), you can utilize the code snippet

$location.path('/cars/' + car.id + '/' + photoId).replace()
.

When using ngRoute for routing in Angular, the framework will intercept the location change and prevent the page from refreshing unnecessarily. The route parameters should correspond with "/cars/:carId/:photoId?", where the "?" signifies that the final parameter is optional. By employing the .replace() function, users are spared from having to navigate back through all the images manually.
