Attaching a click event to a nested element within an AngularJS directive

I am currently working with the following directive.

(function () {
    'use strict';
    angular.module('ap.App')
        .directive('clearCancelFinishButtonsHtml', function () {
            return {
                scope: {
                    clearFunction: '='
                },
                replace: true,
                templateUrl: 'directives/clearCancelFinishButtons.html',
                link: function (scope, el, attrs) {
                    var clear= angular.element(el.find('button.clear'));
                    console.log(el.find('.clear'));
                    clear.bind("click", function () {
                        alert("here");
                    });
                }
            }
        });
})();

In my code, the above directive is associated with the following HTML structure:

<div class="row pull-right">
    <div class="col-lg-12 col-md-12 col-sm-12">
        <button type="button" class="custom-default clear">CLEAR</button>
        <button type="button" class="custom-danger">CANCEL</button>
        <button type="button" class="custom-info" ng-click="ap.save()">FINISH</button>
    </div>
</div>

The main goal I have is to target the button with the clear class within the directive and trigger a click event on it. However, despite being able to implement the click event for the element itself, I'm facing difficulties in binding it to the child element. Any assistance or suggestions on this matter would be highly appreciated.

PS. The way I am using the directive is

<clear-cancel-finish-buttons-html id="{{$id}}" clear-function="'resetConfigurationPageInputs'">
</clear-cancel-finish-buttons-html>

UPDATE----------

My ultimate objective is to dynamically add and remove functions directly from the directive declaration itself.

Thank you everyone for your efforts,

I managed to make it function with this piece of code.

(function () {
    'use strict';
    angular.module('ap.App')
        .directive('clearCancelFinishButtonsHtml', function () {
            return {
                scope: {
                    clearFunction: '='
                },
                replace: true,
                templateUrl: 'directives/clearCancelFinishButtons.html',
                link: function (scope, el, attrs) {
                    var buttons=el.find('button');
                    angular.forEach(buttons, function(button){
                        var buttonEl=angular.element(button);
                        if(buttonEl.hasClass("clear")){
                            buttonEl.bind("click", function () {
                              alert("here");
                          });
                        }
                    })

                }
            }
        });
})();

Wishing you productive coding sessions ;)

Have you considered using ng-click for this task?

If you implement the following code snippet:

link: function (scope, el, attrs) {
  scope.clickHandler = function () { alert('click') };
}

and

<button type="button" class="custom-default click-button" ng-click="clickHandler()">CLICK ME</button>

you will see that the function gets called successfully.

Answer №3

Do you happen to be utilizing jQuery? If not, keep in mind that the .find() method will solely function with tag names, rendering class selectors ineffective. The issue at hand is that el.find('.clear') isn't targeting your child element. Instead, consider using document.querySelector as shown below:

var clear= angular.element(el[0].querySelector('button.clear'));

If jQuery is not part of your project, then only jqlite is available to you. For more information on what can and cannot be achieved with jqlite, refer to the jqlite documentation.
