Chapter 2 }, templateUrl: "alert.html", replace: true }; }); alert.html The left-hand side contains the name of the parameter available inside the directive's scope to be used in the template. The right-hand side contains the name of the attribute declared in the element, whose value will contain the expression to link to the property on the directive's template. By prefixing it with @, the literal value will be used as a parameter. Following this, we are using the = prefix in order to create a bidirectional relationship between the controller and the directive. It means that every time anything changes inside the controller, the directive will reflect these changes: index.html controllers.js parking.controller("parkingCtrl", function ($scope) { $scope.appTitle = "[Packt] Parking"; $scope.alertTopic = "Something went wrong!"; $scope.alertMessage = "You must inform the plate and the color of the car!"; }); directives.js [ 39 ] www.it-ebooks.info
Creating Reusable Components with Directives parking.directive("alert", function () { return { restrict: 'E', scope: { topic: '=topic', description: '=description' }, templateUrl: "alert.html", replace: true }; }); The last situation is when we need to execute something within the context of the parent scope. It could be achieved using the & prefix. In the following example, we are passing a function called closeAlert to the directive, defined by the controller to close the alert box: index.html controllers.js parking.controller("parkingCtrl", function ($scope) { $scope.appTitle = "[Packt] Parking"; $scope.showAlert = true; $scope.alertTopic = "Something went wrong!"; $scope.alertMessage = "You must inform the plate and the color of the car!"; $scope.closeAlert = function () { $scope.showAlert = false; }; }); directives.js parking.directive("alert", function () { return { restrict: 'E', [ 40 ] www.it-ebooks.info
