Answer №1

If a function is used within the template, it will typically be executed twice by AngularJS as a way to ensure that the function runs properly.

You can observe this behavior in action with this JSFiddle example.

HTML:

<div ng-app>
  <div ng-controller="ExampleCtrl">
      {{hey()}}
  </div>
</div>

JS:

function ExampleCtrl($scope) {
  $scope.hey = function() {
    console.log('here I am');   
  }
}

What Should You Do Instead?

Avoid loading data using a function within the template; instead, load it directly when the controller is initialized. Check out this alternative example.

function ExampleCtrl($scope, $http) {
  $http.get(...);
}

PS: If you're not using the `get` method from jQuery, consider utilizing AngularJS's own HTTP methods. Learn more here.
