问题描述

Angularjs文档提供$ controller服务的用法如下: $controller(constructor, locals);

Angularjs docs give the usage of $controller service as: $controller(constructor, locals);

任何人都可以将重点放在这两个方面吗?

Can anyone focus some light on these 2 points:

  1. 何时使用 $ controller 服务.请提供一些用例.
  2. 有关传递给它的"locals"参数的详细信息.
  1. When to use $controller service. Please provide some use case.
  2. Details about 'locals' parameter passed to it.

推荐答案

您可以创建将在$ scope上执行到一个控制器中的通用功能,该功能可能命名为'CommonCtrl'.

You can create common functions which are to be executed on $scope into one controller may be named 'CommonCtrl'.

angular.module('app',[]).controller('CommonCtrl', ['$scope', function($scope){
      var self = this;
      $scope.stuff1 = function(){

      }

      $scope.stuff2 = function(){

      }
      self.doCommonStuff = function(){
               // common stuff here
               $scope.stuff1();
               $scope.stuff2();

      };
      return self;
}]);

然后将此控制器注入其他控制器中,让我们说'TestCtrl1'之类的

And inject this controller in other controllers let say 'TestCtrl1' like

angular.module('app',[]).controller('TestCtrl1', ['$scope','$controller', function($scope, $controller){
        var commonCtrl = $controller('CommonCtrl',{$scope: $scope}); // passing current scope to commmon controller
        commonCtrl.doCommonStuff();
}]);

这里,在$ controller服务的第二个参数中,我们正在传递CommonCtrl所需的依赖项.因此,doCommonStuff方法将使用TestCtrl1控制器的作用域.

Here, the in second argument of $controller service, we are passing dependencies that are required by CommonCtrl. So the doCommonStuff method will use TestCtrl1 controller's scope.
