What is the process for creating custom event bindings in AngularJS?

There is a custom event called core-transitionend (specifically triggered by Polymer), and I am able to specify an event handler using document.addEventListener(). However, what would be the most recommended approach for achieving this in AngularJS?

Alternatively, I could directly define a handler in the DOM like so:

<paper-ripple on-core-transitionend="enter()"></paper-ripple>
, but how can I implement this function in AngularJS?

Answer №1

To view an example, check out this fiddle where I've implemented a custom directive that links an event to the element.

angular.module('HelloApp', [])
    .directive('customDir', function () {
        return {
            restrict: 'A',

            link: function(scope, element, attrs)      
            {
                element.bind("click",function()
            {
            alert("you clicked me");

        })
            }    


        }
    })

You can easily bind your specified event to the element in your particular situation.

Answer №2

Here is a simple way to integrate your custom element with both AngularJS and Polymer:

  1. Enclose your custom element within an auto-binding template.
  2. Establish bindings between AngularJS scope and Polymer scope (template element).

That's all you need to do!

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<link href="https://www.polymer-project.org/components/polymer/polymer.html" rel="import">

<link href="https://www.polymer-project.org/components/paper-button/paper-button.html" rel="import">
<div ng-app="demo-app">
  <div ng-controller="DemoController">
    <template bind-events="clickMe,mouseOver" is="auto-binding">
      <paper-button raised on-tap="{{clickMe}}" on-mouseover="{{mouseOver}}">click me</paper-button>
    </template>
    <pre>
            <code>
            {[{text}]}
            </code>
            </pre>
  </div>
</div>
<script>
  angular.module('demo-app', [])
    .config(function($interpolateProvider) {
      $interpolateProvider.startSymbol('{[{').endSymbol('}]}');
    })
    .directive('bindEvents', function() {
      return {
        restrict: 'A',
        link: function(scope, element, attrs) {
          eventNames = attrs.bindEvents.split(',');
          eventNames.forEach(function(eventName) {
            element[0][eventName] = scope[eventName];
          });
        }
      }
    })
    .controller('DemoController', function($scope) {
      $scope.text = '';
      $scope.clickMe = function() {
        $scope.text += '\nyou clicked me!!';
        $scope.$apply();
      };
      $scope.mouseOver = function() {
        $scope.text += '\nyou hovered me!!';
        $scope.$apply();
      }
    });
</script>

Alternatively, if duplicating the entire scope isn't a concern, you can follow this approach:

    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
    <link href="https://www.polymer-project.org/components/polymer/polymer.html" rel="import">

    <link href="https://www.polymer-project.org/components/paper-button/paper-button.html" rel="import">
    <div ng-app="demo-app">
      <div ng-controller="DemoController">
        <template bind-angular-scope is="auto-binding">
          <paper-button raised on-tap="{{clickMe}}" on-mouseover="{{mouseOver}}">click me</paper-button>
        </template>
        <pre>
                <code>
                {[{text}]}
                </code>
                </pre>
      </div>
    </div>
    <script>
      angular.module('demo-app', [])
        .config(function($interpolateProvider) {
          $interpolateProvider.startSymbol('{[{').endSymbol('}]}');
        })
        .directive('bindAngularScope', function() {
        return {
                restrict: 'A',
                link: function(scope, element, attrs) {
                    for(k in scope) {
                    if (!element[0][k]) {
                    element[0][k] = scope[k];
                    }
                    }
                }
            }
        })
        .controller('DemoController', function($scope) {
          $scope.text = '';
          $scope.clickMe = function() {
            $scope.text += '\nyou clicked me!!';
            $scope.$apply();
          };
          $scope.mouseOver = function() {
            $scope.text += '\nyou hovered me!!';
            $scope.$apply();
          }
        });
    </script>

Please note: I had to modify Angular's interpolation symbol to ensure compatibility between AngularJS and Polymer components.
