Angular Directive to component angular 1.5

问题

I have this directive, that i would like to make a component

angular.module('app')
.directive('year', function () {
    var controller = ['$scope', function ($scope) {
        $scope.setYear = function (val) {
            $scope.selectedyear = val;
        }
    }];
    return {
        restrict: 'E',
        controller: controller,
        templateUrl: "views/year.html"
    };
});

This is what I got so far:

 angular.module('app') 
.component('year', {
        restrict: 'E',
        controller: controller,
        templateUrl: "views/year.html"
    });

I am not sure how to move my var controller into .component

回答1:

There are few things you should do convert your directive to component

• There is no restrict property for component as it is restricted to elements only.
• For controller you could just set as you did at directive declaration but outside of it.
• Controllers for components use controllerAs syntax as default so get rid of $scope

So your component should look like this...

angular.module('app') 
    .component('year', {
        controller: ComponentController,
        templateUrl: "views/year.html"
    });

function ComponentController(){
    var $ctrl = this;

    $ctrl.setYear = function (val) {
       $ctrl.selectedyear = val;
    }
}

Your component should look like this:

function YearController() {
  var $ctrl = this;

  $ctrl.setYear = function (val) {
    $ctrl.selectedyear = val;
  }
}

angular.module('app').component('year', {
  templateUrl: 'views/year.html',
  controller: YearController
});

For more details, please read the following Stack Overflow question for more deatils: Angular 1.5 component vs. old directive - where is a link function? and the official documentation: https://docs.angularjs.org/guide/component

Also, please note that components are restricted to elements only by default.
