Add a close button to an Angular directive

Question

Add a close button to an Angular directive

I'm currently working on creating an alert message with the following layout:

<div class="alert">
    <p>Some alert content!</p>
</div>

Everything is looking good so far. Now, I want to enhance this alert by adding a close button using a directive. When the button is clicked, the alert should be hidden.

Here is the directive I've created:

myApp.directive('alert', function() {
    return {
        restrict: 'C',
        link: function(scope, elem, attrs) {
            elem.prepend('<a class="alert-close" ng-click="close()"></a>');
        }
    }
});

The directive successfully adds the close button, but now I need help with figuring out how to implement the functionality to hide the alert when the button is clicked.

If anyone has any tips or suggestions on how to achieve this, I would greatly appreciate it. Thank you in advance!

Answer №1

To enhance your directive, you have the option of adding a controller where you can include the close method within the scope.

myApp.directive('notification', function() {
    return {
        restrict: 'E',
        link: function(scope, elem, attrs) {
            elem.prepend('<a class="close-notification" ng-click="close(this)"></a>');
        },
        controller: function ($scope) {
          $scope.close = function (obj) {
            // Perform operations on obj (the anchor link) or navigate up the DOM tree.
          };
        }
    }
});
