How to detect if a user clicks browser back button in Angularjs

Question

I have a form-like page with some data. And want to show a popup/alert when a user clicks the browser back button, asking \"if they want to go back or stay on the same page\

Answer 1

Here is my solution

app.run(function($rootScope, $location) {
    $rootScope.$on('$locationChangeSuccess', function() {
        if($rootScope.previousLocation == $location.path()) {
            console.log("Back Button Pressed");
        }
        $rootScope.previousLocation = $rootScope.actualLocation;
        $rootScope.actualLocation = $location.path();
    });
});
