Maintain the current states when returning to a previous point in time

In my Angular app, I have multiple pages that allow users to make changes such as opening tabs and pills, modals, etc. For instance, if a user opens a modal and then clicks a link within that modal that takes them to another page, I want the original page to be displayed when they navigate back in their browser history. This means keeping the modal open instead of resetting the page.

I am currently using ui-router with Angular 1.4.3.

Although I have explored resources like:

...they do not fully address my specific need. I am uncertain about how to search for a solution to this issue effectively.

Another scenario is when a user enters a query in a search bar, clicks on a result that leads to a new page, and upon returning, they have to re-enter the search term. This can be frustrating for users.

Answer №1

Utilize a Dedicated Service for Storing Page State

Instead of cluttering the $scope with page state and user input, opt to store them in a persistent service that can be injected into the page controller alongside the $scope.

Create a reference to the service within the $scope:

myApp.service('MyPageStateService', function() {
    this.someProperty = 'some initial state';
});

myApp.controller('MyPageController', function($scope, MyPageStateService) {
    $scope.state = MyPageStateService;
});

Then, access the stored data from the persistent state service in the page template:

<div ng-controller="MyPageController">
    <p>The current state of my page is {{state.someProperty}}</p>
</div>

Upon returning to the page within the app, the controller will receive a new $scope, but it will retain the same instance of MyPageStateService.

Answer №2

For a solution to maintain consistent navigation, consider utilizing sticky states. These states offer more than just forward/back functionality.

If you only want this behavior for forward/back actions, one approach could be executing $stickyState.reset('...') during $stateChangeStart, excluding the adjacent state from the reset process.
