Guide on connecting event to a dom element generated within the link function

I understand that a DOM element created in a template function can be linked to an event in the controller, like this:

angular.module('app', [])
  .directive('appClick', function(){
     return {
       restrict: 'A',
       scope: true,
       template: '<button ng-click="click()">Click me</button> Clicked {{clicked}} times',
       controller: function($scope, $element){
         $scope.clicked = 0;
         $scope.click = function(){
           $scope.clicked++
         }
       }
     }
   });

Since there is no scope in the template, I have to use the link function. How could I achieve the same result using the link function, like so:

 angular.module('app', [])
      .directive('appClick', function(){
         return {
           restrict: 'A',
           scope: true,
           link:function(scope, element, attrs){
  element.html('<button ng-click="click()">Click me</button> Clicked {{clicked}} times')
},
           controller: function($scope, $element){
             $scope.clicked = 0;
             $scope.click = function(){
               $scope.clicked++
             }
           }
         }
       });

How do I attach an event here?

Answer №1

When working with AngularJS, it is necessary to compile any additional DOM elements before attaching them to the existing DOM. This can be done using the $compile service on the desired scope. Templates in AngularJS typically include AngularJS-specific syntax, which is why compilation is required. Below is a sample code snippet demonstrating this process:

var myApp = angular.module('myApp', []);

myApp.controller('mainController', ['$scope', function($scope){
   $scope.message = 'Welcome message';
}])

myApp.directive('myTemplate', ['$compile',function($compile) {
  return {
    restrict: 'A',
    scope: true,
    link: function(scope, element, attr) {
    
      var el = $compile('<button ng-click="click()">Click me</button> Clicked {{clicked}} times')(scope);
      element.append(el);

      scope.clicked = 0;
      scope.click = function(){
         scope.clicked++
      }
    }
  }
}])
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<div ng-app="myApp">
  <div ng-controller="mainController">
    {{message}}
    <div my-template></div>
  </div>
</div>

Answer №2

 const myApp = angular.module('app', [])
  .directive('appClick', function(){
     return {
       restrict: 'A',
       scope: true,
       link:function(scope, element, attrs){

           element.html('<button ng-click="click()">Click me</button> Clicked {{clicked}} times')

             scope.clicked = 0;
             scope.click = function(){
               scope.clicked++
             }
         }
       });
