Function call from angular

Question

How can I call a function in my controller from the $ scope.watch function? I try something like this, but it does not work.

$scope.$watch(function(){return self.user}, function (newVal, oldVal, scope){
if (self.user) {
    getNotificationCount();
  } 
});

var getNotificationCount = function(){
  console.log("called your function");
}

it gives me an error

TypeError: getNotificationCount is not a function

Answer 1

You need to determine getNotificationCountbefore calling it.

var getNotificationCount = function(){
  console.log("called your function");
}

$scope.$watch(function(){return self.user}, function (newVal, oldVal, scope){
  if (self.user) {
    getNotificationCount();
  } 
});

Answer 2

Declare a function in the angular scope:

$scope.getNotificationCount = function(){
  console.log("called your function");
}
