What is the best way to reload (using F5) and navigate to a new page using AngularJS?

Question

What is the best way to reload (using F5) and navigate to a new page using AngularJS?

In my web application, there are two pages with forms: purchase1 and purchase2.

If a customer refreshes the purchase2 page, I want them to be redirected back to purchase1.

I've been struggling to achieve this by configuring a setup like:

.config(function($stateProvider, $urlRouterProvider) {
    $urlRouterProvider.when('/purchase2', '/purchase1');
}

However, this approach prevents me from ever reaching the purchase2 page.

What I really need is for this redirection to occur only when a user manually refreshes the page.

Is there a way to accomplish this? Perhaps an Angular function that triggers on Refresh?

Something along the lines of:

$scope.onRefresh = function(){
   $location.path('/dashboard/purchase1');
}

So far, I haven't come across anything like it.

If you want to detect when a user tries to leave a page or refresh it, you can use the beforeunload event. This event is triggered when someone presses F5 or reloads the page in any way. Here's an example of how you can implement this:

var windowElement = angular.element($window);
windowElement.on('beforeunload', function (event) {
    event.preventDefault();
    // Add your code here for redirection.
    $window.location.href = '/purchase1';
});

Make sure to place this code on the purchase2 page.

Achieving this is possible.

To set up a universal listener for state changes, follow these steps:

$scope.$on('$stateChangeStart', function(event, toState, toParams, fromState) {
    // Determine if the user is refreshing the page or navigating between states
    if (toState.name == 'destination' && !fromState) {
        $state.go('origin');
        event.preventDefault();
        return;
    }
});

When I say global, I mean implementing the above code in a controller accessible throughout your application, like a controller attached to your body or html tag.

Assuming that origin and destination are the names of your states for different pages. If they represent parameters within a common state, you may need to tweak the provided code accordingly.

On every refresh, the same actions take place as they do on initial loading.

One suggestion is to verify if the user has previously visited by utilizing cookies for tracking and retrieval later on.

Nevertheless, it might be worth reconsidering your approach. Why dedicate effort to causing the refresh function to perform inadequately?

In my opinion, utilizing server-side applications like PHP or JSP would be more effective than using JavaScript in this scenario. This is because JavaScript lacks knowledge of the previous page and is rendered only after the page has loaded. By checking the request-header in your server side application, you can access the current URL and seamlessly redirect the user to a new URL.

To control the flow, you can set a flag called purchase2-loaded and store this variable in the browser's localStorage. Subsequently, create an immediately-invoked function expression (IIFE) to monitor the value of this variable and redirect to purchase1 accordingly.

Additionally, upon reaching purchase1, remember to reset it to false.

Please note: This code is written purely in JavaScript and utilizes localStorage.

Sample Code

(function(){
  var isPurchase2Loaded = localStorage.getItem("Purchase2");
  if(isPurchase2Loaded || isPurchase2Loaded === undefined){
    document.write("Redirecting to purchase 1...");
  }
  else{
    document.write("Initial load...");
    localStorage.setItem("Purchase2", true);
  }
})()

After some investigation, I managed to resolve the issue in the following way:

In the file purchase1.js, I included the following line inside the submit() function:

$rootscope.demographic=1;

In purchase2.js, I added the following code snippet to the controller:

var init = function(){
      if(angular.isUndefined($rootScope.demographic)){
           $location.path('/purchase1');    
      }

    };
    init();

This solution works because when we refresh (F5) the page, it essentially restarts the application, resetting the $rootscope and making "Demographic" undefined.

When entering purchase2, the "init" function will execute. If we navigate from purchase1, everything will work as expected with a defined demographic value. Otherwise, we will simply redirect back to purchase1.
