Leveraging the $broadcast method within a $interval function in AngularJS

After extensively searching this site and using Google, I have been unable to find a solution. I have one module dedicated to services and another for the app itself. In the services module, I have the following code snippet:

$interval(function(){
    $rootScope.$broadcast('tick');
},1000);

In the app section, I have:

$scope.$on('tick'), function(event){
    alert('tick');
}

I came across this model on a jsfiddle. Although 'tick' appears to be triggered without any errors in the console, the app code fails to execute...

Answer №1

According to the official documentation, the correct syntax for using the $on method is as follows: $on(name, listener)

It appears that there may have been some confusion in copying and pasting code, causing the listener function to be defined incorrectly outside of the $on method.

To rectify this issue, simply move the right parentheses that comes immediately after 'tick' to the end of the listener function definition, like so:

$scope.$on('tick', function(event){
    alert('tick');
});
