AngularJS controller and methods

rated 0 times [ 65] [ 6] / answers: 1 / hits: 64727 / 12 Years ago, fri, january 18, 2013, 12:00:00

I'm a beginner in angularjs with a few questions about controllers.

Here's my example controller:

function exampleController($scope)

{

   $scope.sampleArray = new Array();



   $scope.firstMethod = function()

   {

      //initialize the sampleArray

   };



   $scope.secondMethod = function()

   {

      this.firstMethod();

   };

};

Here are my questions:

How I can call firstMethod from secondMethod? Is the way I did it correct, or is better way?

How I can create a constructor for the controller? I need to call the secondMethod that call the firstMethod that initialize the sampleArray?

How I can call a specific method from html code? I found ng-initialize but I can't figure out how to use it.

You call a method the same way you declared it:

$scope.secondMethod = function() {

  $scope.firstMethod();

};

Which you can also call from HTML like so:

<span>{{secondMethod()}}</span>

But controllers don't really have constructors - they're typically used just like functions. But you can place initialization in your controller function and it will be executed initially, like a constructor:

function exampleController($scope) {

  $scope.firstMethod = function() {

    //initialize the sampleArray

  };



  $scope.secondMethod = function() {

    $scope.firstMethod();

  };



  $scope.firstMethod();

}
