Utilizing reference memory to enable communication between two controllers

Within my Angular application, I have implemented a service to facilitate communication between 2 controllers and allow them to share the input variable from the search box.

I am using kickSearch.box to reference memory...obj.property. However, there seems to be an issue where updates to kickSearch.box do not reflect in $scope.searchBox:

angular.module('ucp.kick').controller('kickSearch', function($scope, $location, kickSearch) {
  initialize = function() {
    var terms;
    $scope.searchBox = kickSearch.box;
    terms = $location.search().device || $location.search().dc || [];
    kickSearch.box = _.isArray(terms) ? terms.join(" ") : terms;
    if ($scope.searchBox.length) {
      return $scope.submitSearch();
    }
  };
  initialize();

 <input type="text" class="form-control" placeholder="Enter device #" ng-model="searchBox" >

Answer №1

The reason for this is that $scope.searchBox does not hold a direct reference to kickSearch.box, but only contains its current value at the time of request.

To keep your controller updated when changes occur in your service, one approach is to utilize methods such as $rootScope.$broadcast or $rootScope.$emit to inform the controller about updates in the service. Subsequently, the controller can then retrieve the latest value directly from the service.
