Question

One way to directly invoke a route configuration from a controller in Javascript is to avoid using an `<a href>` click event in the HTML

Seeking guidance as a newcomer to routing and Single Page Applications in AngularJS. I am currently facing an issue and would greatly appreciate any assistance in resolving it.

Background

I have a "Products list" page showcasing products in a ng-repeat loop. Upon clicking on a product link, the application navigates to a "Details" page (an extension of the 'Products list' page in SPA) for that specific 'id' through an href call.

<a href="{{id}}/Details" class="button"> Details

In order to route to the 'Details' page, we established an app.config as follows

in Productslist.js
-------

$routeProvider
    .when("/:id/Details",{ templateUrl : "../ProductsList/Details" , controller :})
    .otherwise({
        templateUrl : "/"
    });

The current flow works seamlessly, allowing me to open the 'Details' page when I am on the 'Products list' page and click on the 'Details' button for any displayed products.

If relevant, the URL appears like: www.abc.com/list/4/Details, showing the details of product id = 4.

Issue / Desired Outcome

Now, from another third page "X", where the Product-ID is obtained, I aim to directly navigate to the product details page without needing to click the "Details" button on Page A.

Given that the module for this page was initially created in the 'Products list' page, I am passing the 'id' value from page X into ProductList.js and intend to set the URL as such to access the 'Details' page.

if(fromPageX == 'true')
{
var x = id+"/Details";
location.href = x;   // bypass waiting on page productsList.html, directly open 'Details' page
}

Essentially, my goal is to trigger the "routing" function from the controller in the .js file rather than via the .html file (on-click).

The browser URL correctly displays: www.abc.com/A/4/Details; however, I encounter a 404 - page not found error since it isn't passing through the routing configuration. I've attempted Window.location.href and other suggestions from various sources, yet I'm unable to successfully load the 'Details' page.

Is this scenario achievable in AngularJS?
What could be going wrong in my approach?

Appreciate your help and support in advance!

Answer №1

If you're unsure about where the logic for page X is being executed, there are a couple of options available to you. You can either capture it in the resolve of the route for page X or handle it within the controller for page X. Opting to catch it in the resolve would be the recommended approach as it prevents the loading of the page X controller initially.

Implementing the resolve method: Within the page X .js file, include a resolve block that captures the ID before the route resolves and redirects accordingly.

            $routeProvider
            .when("PAGE_X/:id",{ 
                templateUrl : "../ProductsList/PAGE_X" , 
                controller : 'pageXController',
                resolve: {
                    redirect: ['$q', '$location', '$routeParams' function($q, $location, $routeParams) {
                        var deferred = $q.defer();
                        if ($routeParams.id) {
                            $location.path("/A/"+ $routeParams.id + "/Details")
                            deferred.resolve();
                        } else deferred.resolve();
                        return deferred.promise;
                    }]
            }
            })
            .otherwise({
                templateUrl : "/"
            });

Using the redirect approach: This method involves adding the code snippet below into the PAGE_X controller. Instead of using traditional methods like window.location, utilize Angular's $location method (ensure that $location is injected as a dependency) - refer to https://docs.angularjs.org/guide/$location

if(fromPageX == 'true')
{
var x = "A/" + id+"/Details";
$location.path(x);
}
