What is the process of linking current components to Angular?

New to Angular and currently navigating my way through an existing codebase.

There is a particular element that already exists in the root document (index.html) before Angular library is loaded. Due to this, the ng-click directive does not get registered.

Is there a simple method to provide Angular with a reference to this specific element so it can be recognized as its own?

Below is some sample code showcasing the issue (missing parts for demonstration purposes only):

<html>
<body ng-app="allMyCookiesApp">
    <a ng-click="giveGeuisACookie()">GIMME</a>
    <script src="angular.js"></script>
</body>
</html>

I am eager to receive a cookie when I click on GIMME.

Answer №1

ng-app initializes everything inside when angular loads. It handles compiling and linking ng-click in the given example. The root issue may lie elsewhere.

The key missing component here is a controller. It seems likely that a controller is needed to assign the giveGeuisACookie method correctly within the scope for use by ng-click.

angular.module('allMyCookiesApp', [])
  .controller('geuisCtrl', function($scope) {
      $scope.giveGeuisACookie = function() {
          // Cookie time
      };
   });

This snippet creates the module for ng-app and sets up a controller. The controller then includes the giveGeuisACookie method within its scope.

<html>
    <body ng-app="allMyCookiesApp" ng-controller="geuisCtrl">
        <a ng-click="giveGeuisACookie()">GIMME</a>
        <script src="angular.js"></script>
    </body>
</html>

This code instructs angular to utilize the controller so that ng-click can access the correct method. If this doesn't resolve the issue, consider providing a jsfiddle with a sample of your current (working or non-working) implementation.
