如何从AngularJs中的另一个控制器访问控制器 [英] How to access a controller from another controller in AngularJs

问题描述

我想使用Angularjs模块中另一个Controller的另一种方法. 我有两个名称为Controller的控制器: bookApp 模块中的 Booklist 控制器. 另一个名为 ShowEachBook . 在 Booklist 控制器中，创建 ViewItem()方法，该方法可从 ShowEachBook 控制器中的 View_A_book()方法访问.

I want to use another method from another Controller in an Angularjs Module. I have two Controller one named: Booklist Controller in bookApp Module. and another one named ShowEachBook. In Booklist Controller I create ViewItem() method which can be accessible from View_A_book() method in ShowEachBook Controller.

这是我在BookApp模块中的控制器

Here is my Controller in BookApp module

var bookApp = angular.module('bookApp', []);

bookApp.controller('bookListCtr', function ($scope, $http) {

    $scope.ViewItems = function ($id) {
        $this->View_A_book($id);// This is example because I want to used View_A_book() method here
    };
 })

这是 ShowEachBook 控制器

bookApp.controller('ShowEachBook', function ($scope, $http) {

  $scope.View_A_book = function($id){
       /// get book from server.
  }
})

推荐答案

创建工厂. 您只需要定义一次，就可以从任何控制器中注入和调用它. 看到这个文章.

Create a factory. You only have to define it once, and it can be injected and called from any controller. See this article.

制造一个工厂ViewBook，并向其中添加您的功能: 您的工厂:

Make a factory ViewBook, and add your function to it: Your factory:

angular.module('bookApp')
    .factory('ViewBook', function () {
        return {
            view_a_book: function(id) {
                //do whatever you want to.
                return something 
            },
        };
    });

您的控制器:

var bookApp = angular.module('bookApp', []);

bookApp.controller('bookListCtr', function ($scope, $http, ViewBook) {

    $scope.ViewItems = function ($id) {
        ViewBook.view_a_book($id);
    };
 })

使用$scope和$http添加对工厂的引用，然后使用该引用进行调用.可以对您拥有的任何控制器重复此操作.

You add a reference to the factory with $scope and $http, and use that to call it. This can be repeated for any controllers you have.
