如何从链接功能访问与指令相关的控制器实例？

return { 
      template: template, 
      controller: controller, 
      controllerAs: 'myCtrl', // How do I access the controller instance from the link function? 
      restrict: 'E', 
      replace: true, 
      link: function(scope, element, attrs) {} 
};

指令中的链接函数接受第4个参数。您可以执行以下操作：

  return { 
      template: template, 
      controller: controller, 
      controllerAs: 'myCtrl', 
      restrict: 'E', 
      replace: true, 
      link: function(scope, element, attrs, controller) {} 
     };
