您可以使用事件的系統，例如，你可以在這裏看到：http://jsfiddle.net/patxy/RAVFM/

如果你有2個控制器，共享服務，你可以這樣做的：

var myModule = angular.module('myModule', []); 
myModule.factory('mySharedService', function($rootScope) { 
    var sharedService = {}; 

    sharedService.message = ''; 

    sharedService.prepForBroadcast = function(msg) { 
    this.message = msg; 
    this.broadcastItem(); 
    }; 

    sharedService.broadcastItem = function() { 
    $rootScope.$broadcast('handleBroadcast'); 
    }; 

    return sharedService; 
}); 

function ControllerZero($scope, sharedService) { 
    $scope.handleClick = function(msg) { 
    sharedService.prepForBroadcast(msg); 
    }; 

    $scope.$on('handleBroadcast', function() { 
    $scope.message = sharedService.message; 
    });   
} 

function ControllerOne($scope, sharedService) { 
    $scope.$on('handleBroadcast', function() { 
    $scope.message = 'ONE: ' + sharedService.message; 
    });   
} 

function ControllerTwo($scope, sharedService) { 
    $scope.$on('handleBroadcast', function() { 
    $scope.message = 'TWO: ' + sharedService.message; 
    }); 
} 

ControllerZero.$inject = ['$scope', 'mySharedService'];   

ControllerOne.$inject = ['$scope', 'mySharedService']; 

ControllerTwo.$inject = ['$scope', 'mySharedService'];
