[javascript] Angularjs on page load call function

I am learning AngularJS. I have some article tag and on clicking on a button each article page is showed without any page refresh. This is one page website. What I want is that when article id "showSelector" is loaded I want to call myFunction() and in this function I want to show an alert. But the alert is not showing.

How can I do that?

 <article id="showSelector" class="panel" ng-controller="CinemaCtrl" onload="myFunction()">
      <header>
        <a ng-click="back()" class="icon fa-arrow-circle-left"></a><h2>Shows in {{getSelectedCinema()}}</h2>        
      </header>
      <p>
        These shows are played in our single room theatre. Select one to reserce a ticket for it.
      </p>
      <section>
        <div class="row">
          <div class="4u" ng-repeat="show in shows">
            <div class="movieCard">
              <a ng-click="selectShow(show)"></a>
              <h3>{{show.nameOfShow}}</h3>
              <h4>{{show.timeOfShow | date:'MMM d'}}</h4>
              <h4>{{show.timeOfShow | date:'HH:mm'}}</h4>
              <p>Free seats: {{show.reservations | freeSeatFilter}}</p>
            </div>
          </div>
        </div>
      </section>
      <script>
function myFunction() {
    alert("Page is loaded");
};
</script>
    </article>

you can also use the below code.

function activateController(){
     console.log('HELLO WORLD');
}

$scope.$on('$viewContentLoaded', function ($evt, data) {
    activateController();
});

Instead of using onload, use Angular's ng-init.

<article id="showSelector" ng-controller="CinemaCtrl" ng-init="myFunction()">

Note: This requires that myFunction is a property of the CinemaCtrl scope.

It's not the angular way, remove the function from html body and use it in controller, or use

angular.element(document).ready

<section ng-controller="testController as ctrl" class="test_cls"  data-ng-init="fn_load()">

$scope.fn_load = function () {
  console.log("page load")
};

you can use it directly with $scope instance

     $scope.init=function()
        {
            console.log("entered");
            data={};
            /*do whatever you want such as initialising scope variable,
              using $http instance etcc..*/
        }
       //simple call init function on controller
       $scope.init();

    var someVr= element[0].querySelector('#showSelector');
        myfunction(){
        alert("hi");
        }   
        angular.element(someVr).ready(function () {
           myfunction();
            });

This will do the job.
