How come my $scope variables are not resetting when attempting to refresh the data?

I just started working with Angular and encountered an issue while trying to implement a reload button. My webpage displays a table with data pulled from a Parse database. The table can be modified using various buttons, and after making changes, I want to reload the table to reflect the original database data and undo any alterations made. Any guidance on how to achieve this would be highly appreciated!

$scope.reset = function() {
        $scope.compOrder = [];
        $scope.foundIndex = -1;
        $scope.selectedItem = {};
        $scope.citySelect($scope.currentCity);
    }
    

To provide more context, below is the code snippet containing additional information. Please note that the citySelect function retrieves data from Parse to populate the model.

var myApp = angular.module('CompetitionManager',[]);
    
    myApp.controller('MainController', ['$scope', function($scope) {

        // Controller logic here...

    }]);
    

Answer №1

In order for the UI to reflect changes in scope, make sure to use $scope.$apply() to trigger the digest cycle.

$scope.reset = function() {
    ...

    $timeout(function() {
       $scope.$apply();
    });
}

Using $timeout ensures that the digest cycle runs after the current call stack is cleared to avoid conflicts.
