从另一个控制器 Angular Js 调用函数 [英] Call function from another Controller Angular Js

问题描述

我是使用 angular js 的新手，我已经声明了许多控制器，现在我想将一个控制器的用户功能转换为另一个控制器.这是我的示例代码.

I am new to using angular js and i have declare many controller and now i want to user function of one controller into another controller. here is my sample code.

app.controller('Controller1',function($scope,$http,$compile){
    $scope.test1=function($scope)
    {
          alert("test1");
    }
});

app.controller('Controller2',function($scope,$http,$compile){
    $scope.test2=function($scope)
    {
          alert("test1");
    }
});
app.controller('Controller3',function($scope,$http,$compile){
  ///
});

现在我想在控制器 3 中调用 test2 函数.有没有人可以帮忙..感谢 Avance... :)

Now i want to call test2 function inside controller3. Can anybody help.. Thanks in Avance... :)

推荐答案

您不能从控制器内的控制器调用方法.您将需要提取该方法，创建一个服务并调用它.这也将使代码彼此解耦并使其更具可测试性

You can't call a method from a controller within a controller. You will need to extract the method out, create a service and call it. This will also decouple the code from each other and make it more testable

(function() {
    angular.module('app', [])
        .service('svc', function() {
            var svc = {};

            svc.method = function() {
                alert(1);
            }

            return svc;
        })
        .controller('ctrl', [
            '$scope', 'svc', function($scope, svc) {
                svc.method();
            }
        ]);
})();
