When you press the back button and navigate to a different page, the scroll position will remain unchanged

Question

When you press the back button and navigate to a different page, the scroll position will remain unchanged

I'm facing an issue with scrolling on my angularjs app.

Currently, the app consists of 2 pages: The first page displays a list of customers, where you can select one to view their details. The second page is a list of companies, following a similar selection process.

To navigate between these pages, I am using a panel along with $location.path(). Additionally, there is a back button implemented using $window.history.back().

The problem arises when selecting an item from either the customers or companies list and then pressing the back button - the app returns to the previous page while maintaining the scroll position. This behavior occurs without any custom implementations, solely relying on $window.history.back().

However, the issue happens when transitioning to another page (without scrolling) after using the back button - the scroll position remains unchanged. Yet, simply scrolling even slightly will reset the position. Furthermore, if the back button isn't used, everything functions as expected.

Therefore, the main concern is determining how to reset the scroll position when moving to another page post the use of $window.history.back().

It's worth noting that I have incorporated the infinite-scroll plugin, although disabling it did not impact the situation, leading me to believe the plugin itself is not the cause of the problem.

A while back, I encountered a similar issue and devised a simple workaround (although not the most elegant one).

My solution involved storing the wrapper's scrolltop value in the scope when the view changed, and then reapplying that value when navigating back.

I can't quite recall how it behaved when using the browser's back button, so you might want to test that out.

If you're interested, here's the code snippet for changing the view and storing the scrollTop value: https://github.com/jedrzejchalubek/Reed/blob/master/src/app/controller/all.js#L20

angular.extend($scope.view, {
    panel: false,
    section: 'single',
    single: el,
    scrollPosition: $('#thumbs').scrollTop()
});

And here's how to go back and reapply the scrollTop value: https://github.com/jedrzejchalubek/Reed/blob/master/src/app/directives/back-to-list.js#L14

scope.$apply(function() {
    scope.view.section = 'list';
    scope.view.panel = false;
});
$('#thumbs').scrollTop(scope.view.scrollPosition);

To capture reload events, simply trigger functions within the initialization of your controller. Make sure these controllers are enclosed in an Immediately Invoked Function Expression. Here's how it can be done:

(function() {

 angular.module("pstat")
         .controller("homeCtrl", homeCtrl);

  homeCtrl.$inject = ['$log', 'dataService', 'localStorageService', '$http'];
  function homeCtrl ($log, dataService, localStorageService, $http) {
    var vm = this;
    $(document).getElementById("yourId").scrollTop(0);

  });
})()

By implementing this approach, the page will reset to a vertical scroll offset of 0 when the controller is initialized, such as when navigating back to this page using $window.history.back event.

After making some modifications to the well-known phonecatApp based on the AngularJS tutorial, I successfully implemented the following feature:

    phonecatApp.run(function($rootScope, $window) {
        $rootScope.$on('$viewContentLoaded', function(){
            $(document).ready(function(){ window.scrollTo(0, 0); });
        });
