I have $rootScope
injected into the factory. The factory returns this function:
alertHook: function() {
$rootScope.$broadcast('getRollups', 'finally');
}
I injected that factory into a directive and call the alertHook()
function.
I am listening for getRollups
like so:
$scope.$on( 'getRollups', function( evt, args ) {
console.log( args );
});
Lo and behold, nothing is logged to the console. I've also tried $emit instead of $broadcast.
Help please, before I go insane :)
With factories use $rootScope.$broadcast
:
angular.module("app",[]) .factory("factory", function($rootScope) { return { broadcast: broadcast }; function broadcast () { $rootScope.$broadcast("myEvent","from factory") } }) .controller("ctrl",function($scope,factory) { $scope.$on("myEvent", function(ev,args) { console.log(ev.name,args); }); $scope.clickMe = function() { factory.broadcast(); }; })
<script src="//unpkg.com/angular/angular.js"></script> <body ng-app="app" ng-controller="ctrl"> <button ng-click="clickMe()">Click me</button> </body>
