可以将本地人注入到使用ng-controller设置的控制器中吗? [英] Can locals be injected into a controller set with ng-controller?

问题描述

请参见下面的示例，是否有一种方法可以使用myCtrl而不是myCtrl2，将参数作为局部变量传递，而不是附加到$ scope?

Referring to the example below, is there a way to use myCtrl instead of myCtrl2, passing an argument as a local instead of attached to $scope?

$ controller 服务完全执行包装现有控制器所需的操作，但无法从模板访问它.

The $controller service performs exactly the operation needed to wrap an existing controller, but it can't be accessed from the template.

<div ng-app>

  <script type="text/ng-template" id="/tpl.html">
    value of y: {{y}}
  </script>

  <div 
    ng-repeat='x in [1,2,3]' 
    ng-controller='myCtrl2'
    ng-include="'/tpl.html'">
  </div>

</div>

function myCtrl($scope, x){
  $scope.y = x * 20;
}

function myCtrl2($scope){
  $scope.y = $scope.x * 20;
}

推荐答案

我不能退出从问题中得知您要查找的内容，但是您可以尝试创建自己的指令( ngController指令的修改版本可以指定控制器注射剂:

I can't quite tell from your question what exatly you're looking for, but you might try creating your own directive (a modified version of the ngController directive) can specify controller injectables:

app.directive('myController', function($controller) {
  return {
    scope: true,
    link: function(scope, elem, attrs) {
      var locals = scope.$eval(attrs.locals);
      angular.extend(locals, {$scope: scope});
      $controller(attrs.myController, locals);
    }
  };
});

您将使用类似以下的方式:

You would use it something like this:

<div my-controller='MainController' locals='{x: "test", y: 42}'></div>
