在角度指令中实现关闭按钮

Question

I am trying to make an alert message and the layout looks like this

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

So far so good, now I want to make a directive to add a close button to this alert and I want to hide the alert when i press the button.

I created this directive

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

Now this directive adds the close button, but I don't know how to implement this button to hide the alert which is inside.

I hope this can be done, thank you in advance for any tips on how to do this.

You can add a controller to your directive as well where you can add the close method to the scope.

myApp.directive('alert', function() {
    return {
        restrict: 'C',
        link: function(scope, elem, attrs) {
            elem.prepend('<a class="alert-close" ng-click="close(this)"></a>');
        },
        controller: function ($scope) {
          $scope.close = function (obj) {
            // manipulate obj (the anchor link) or traverse up the dom etc.
          };
        }
    }
});
