Question

What is the best approach to execute a function in two distinct controllers using angularjs?

My setup includes two distinct angularjs controllers: HomeController and SearchController.

Within HomeController, there is a function named Search().

I am seeking guidance on how to execute the search function from SearchController.

Answer №1

Implement the 'find' method within a factory, then inject this factory into multiple controllers to utilize the 'find' method across them.

Example:

app.controller('MainController', function(searchFactory){
   //Invoke factory method
   //searchFactory.find();
});

app.controller('SecondaryController ', function(searchFactory){
   //Invoke factory method
   //searchFactory.find();
});

app.factory('searchFacotry', function(){
  return{
    find: function(query){
      alert('hello world');
    };
  };
});

Check out this Plunker that I created to demonstrate the concept discussed above. The code snippet below shows the implementation in the app.js file, utilizing a factory declaration. Alternatively, if you only need a function to store and return data, consider using the $rootScope service from Angular as it is globally accessible. Services are preferable when they perform specific operations. For further insights on services versus rootScope, refer to this informative article.


app.controller('DashboardCtrl', function($scope, dataService) {
    $scope.displayData = function() {
        dataService.getData();
    }
});

app.controller('ProfileCtrl', function($scope, dataService) {
    $scope.retrieveData = function() {
        dataService.getData();
    }
});

app.factory('dataService', function(){
    function getData(){
        alert('Hello Universe');
    }
    
    var service = {getData: getData};
    return service;
});
