angularJS1笔记-(13)-自定义指令(controller和controllerAs实现通信)

index.html:

<div ng-app="myApp">
    <div  ng-controller="firstController">

　　index.js:

var myApp = angular.module('myApp', [])
    .directive('bookList', function () { //bookList对应view层的book-list
        return {
            restrict: 'ECAM',
            controller: function ($scope) {
                $scope.books = [
                    {
                        name: 'php'
                    },
                    {
                        name: 'js'
                    },
                    {
                        name: 'java'
                    }
                ];
                this.addBook = function () {
                    //$scope.$apply为全局刷新 在更新完model层数据源$scope.books后也要刷新view层显示
                    $scope.$apply(function () {
                        $scope.books.push({
                            name:'iOS'
                        })
                    })
                }
            },
            controllerAs: 'bookListController', //起一个别名
            template: '<div><ul><li ng-repeat="book in books">{{book.name}}</li></ul><book-add></book-add></div>',
            replace: true
        }
    })
    .directive('bookAdd',function () {
        return{
            restrict:'ECAM',
            require:'^bookList',//^代表向上找标签约束<book-add></book-add>
            template:'<button type="button">添加</button>',
            replace:true,
            link:function (scope, iElement, iAttrs, bookListController) {//把controllerAs: 'bookListController' 注入进来
                iElement.on('click',bookListController.addBook);
            }
        }
    })
    .controller('firstController', ['$scope', function ($scope) {
           //代表当前是给firstController服务的
    }]);

　　运行结果:
