我已经将我的一个角度控制器转换成了语法控制器，但是我很难让ng网格模板很好地发挥作用

<div ng-app="MyApp">
<div ng-controller="MyController">
    {{myMessage}}
    <div ng-controller="MyController2">
        <div ng-controller="MyController3">
            <div ng-controller="MyController4">
                <button id="myButton" ng-click="setMessage('second')">Press</button>
            </div>
        </div>
    </div>
    <script>
        angular.module('MyApp', [])
           .controller('MyController', function($scope) {
            $scope.myMessage = "First";
               $scope.setMessage = function(msg) {
                $scope.myMessage = msg;
               };
        }).controller('MyController2', function($scope) {

           }).controller('MyController3', function($scope) {

           }).controller('MyController4', function($scope) {

           });
    </script>

</div>
</div>

控制器有一个名为“编辑用户”的函数，如下所示

self.editUser = function (user_data) {
    var modalInstance = $modal.open({
        templateUrl: '/admin/views/adminuser.html',
            controller: 'AdminUserController',
            resolve: {
                user_data: function () {
                    return user_data;
                }
            }
        });

        modalInstance.result.then(function () {
            self.myQueryData.refresh = !self.myQueryData.refresh;
        });
    };

<div class="ngCellText" ng-class="col.colIndex()">
    <a ng-click="$parent.$parent.$parent.$parent.editUser({user_id:row.entity.id, first_name:row.entity.first_name, last_name:row.entity.last_name, email:row.entity.email})">
        <span ng-cell-text translate>Edit</span>
    </a>
</div>

.when('/admin/settings', {
    templateUrl: '/admin/views/settings.html',
    controller: 'SettingsController as sc',
})

<div ng-app="MyApp">
<div ng-controller="MyController">
    {{myMessage}}
    <div ng-controller="MyController2">
        <div ng-controller="MyController3">
            <div ng-controller="MyController4">
                <button id="myButton" ng-click="setMessage('second')">Press</button>
            </div>
        </div>
    </div>
    <script>
        angular.module('MyApp', [])
           .controller('MyController', function($scope) {
            $scope.myMessage = "First";
               $scope.setMessage = function(msg) {
                $scope.myMessage = msg;
               };
        }).controller('MyController2', function($scope) {

           }).controller('MyController3', function($scope) {

           }).controller('MyController4', function($scope) {

           });
    </script>

</div>
</div>

ng网格模板如下所示

self.editUser = function (user_data) {
    var modalInstance = $modal.open({
        templateUrl: '/admin/views/adminuser.html',
            controller: 'AdminUserController',
            resolve: {
                user_data: function () {
                    return user_data;
                }
            }
        });

        modalInstance.result.then(function () {
            self.myQueryData.refresh = !self.myQueryData.refresh;
        });
    };

<div class="ngCellText" ng-class="col.colIndex()">
    <a ng-click="$parent.$parent.$parent.$parent.editUser({user_id:row.entity.id, first_name:row.entity.first_name, last_name:row.entity.last_name, email:row.entity.email})">
        <span ng-cell-text translate>Edit</span>
    </a>
</div>

.when('/admin/settings', {
    templateUrl: '/admin/views/settings.html',
    controller: 'SettingsController as sc',
})

<div ng-app="MyApp">
<div ng-controller="MyController">
    {{myMessage}}
    <div ng-controller="MyController2">
        <div ng-controller="MyController3">
            <div ng-controller="MyController4">
                <button id="myButton" ng-click="setMessage('second')">Press</button>
            </div>
        </div>
    </div>
    <script>
        angular.module('MyApp', [])
           .controller('MyController', function($scope) {
            $scope.myMessage = "First";
               $scope.setMessage = function(msg) {
                $scope.myMessage = msg;
               };
        }).controller('MyController2', function($scope) {

           }).controller('MyController3', function($scope) {

           }).controller('MyController4', function($scope) {

           });
    </script>

</div>
</div>

所以当我调用

$parent.$parent.$parent.$parent.editUser

<div ng-app="MyApp">
<div ng-controller="MyController">
    {{myMessage}}
    <div ng-controller="MyController2">
        <div ng-controller="MyController3">
            <div ng-controller="MyController4">
                <button id="myButton" ng-click="setMessage('second')">Press</button>
            </div>
        </div>
    </div>
    <script>
        angular.module('MyApp', [])
           .controller('MyController', function($scope) {
            $scope.myMessage = "First";
               $scope.setMessage = function(msg) {
                $scope.myMessage = msg;
               };
        }).controller('MyController2', function($scope) {

           }).controller('MyController3', function($scope) {

           }).controller('MyController4', function($scope) {

           });
    </script>

</div>
</div>

它不知道我在说什么，除非我包括控制器名称，比如

$parent.$parent.$parent.$parent.sc.editUser,

$parent.$parent.$parent.$parent.getController().editUser

<div ng-app="MyApp">
<div ng-controller="MyController">
    {{myMessage}}
    <div ng-controller="MyController2">
        <div ng-controller="MyController3">
            <div ng-controller="MyController4">
                <button id="myButton" ng-click="setMessage('second')">Press</button>
            </div>
        </div>
    </div>
    <script>
        angular.module('MyApp', [])
           .controller('MyController', function($scope) {
            $scope.myMessage = "First";
               $scope.setMessage = function(msg) {
                $scope.myMessage = msg;
               };
        }).controller('MyController2', function($scope) {

           }).controller('MyController3', function($scope) {

           }).controller('MyController4', function($scope) {

           });
    </script>

</div>
</div>

然后它工作得很好。但是，我不想将此模板直接绑定到sc控制器。如何在不使用控制器名称的情况下调用editUser

<div ng-app="MyApp">
<div ng-controller="MyController">
    {{myMessage}}
    <div ng-controller="MyController2">
        <div ng-controller="MyController3">
            <div ng-controller="MyController4">
                <button id="myButton" ng-click="setMessage('second')">Press</button>
            </div>
        </div>
    </div>
    <script>
        angular.module('MyApp', [])
           .controller('MyController', function($scope) {
            $scope.myMessage = "First";
               $scope.setMessage = function(msg) {
                $scope.myMessage = msg;
               };
        }).controller('MyController2', function($scope) {

           }).controller('MyController3', function($scope) {

           }).controller('MyController4', function($scope) {

           });
    </script>

</div>
</div>

我希望$parent上会有一个函数提供函数名，如

$parent.$parent.$parent.$parent.sc.editUser,

$parent.$parent.$parent.$parent.getController().editUser

<div ng-app="MyApp">
<div ng-controller="MyController">
    {{myMessage}}
    <div ng-controller="MyController2">
        <div ng-controller="MyController3">
            <div ng-controller="MyController4">
                <button id="myButton" ng-click="setMessage('second')">Press</button>
            </div>
        </div>
    </div>
    <script>
        angular.module('MyApp', [])
           .controller('MyController', function($scope) {
            $scope.myMessage = "First";
               $scope.setMessage = function(msg) {
                $scope.myMessage = msg;
               };
        }).controller('MyController2', function($scope) {

           }).controller('MyController3', function($scope) {

           }).controller('MyController4', function($scope) {

           });
    </script>

</div>
</div>

有什么建议吗？

因为您使用的是controllerAs语法，所以您可以通过别名对控制器进行寻址，因此实际的模板行如下所示：

<div ng-app="MyApp">
<div ng-controller="MyController">
    {{myMessage}}
    <div ng-controller="MyController2">
        <div ng-controller="MyController3">
            <div ng-controller="MyController4">
                <button id="myButton" ng-click="setMessage('second')">Press</button>
            </div>
        </div>
    </div>
    <script>
        angular.module('MyApp', [])
           .controller('MyController', function($scope) {
            $scope.myMessage = "First";
               $scope.setMessage = function(msg) {
                $scope.myMessage = msg;
               };
        }).controller('MyController2', function($scope) {

           }).controller('MyController3', function($scope) {

           }).controller('MyController4', function($scope) {

           });
    </script>

</div>
</div>

您可以直接调用父作用域上的函数，而无需引用$parent。因为以后修改视图结构时可能会遇到麻烦

<div ng-app="MyApp">
<div ng-controller="MyController">
    {{myMessage}}
    <div ng-controller="MyController2">
        <div ng-controller="MyController3">
            <div ng-controller="MyController4">
                <button id="myButton" ng-click="setMessage('second')">Press</button>
            </div>
        </div>
    </div>
    <script>
        angular.module('MyApp', [])
           .controller('MyController', function($scope) {
            $scope.myMessage = "First";
               $scope.setMessage = function(msg) {
                $scope.myMessage = msg;
               };
        }).controller('MyController2', function($scope) {

           }).controller('MyController3', function($scope) {

           }).controller('MyController4', function($scope) {

           });
    </script>

</div>
</div>

例如：

<div ng-app="MyApp">
<div ng-controller="MyController">
    {{myMessage}}
    <div ng-controller="MyController2">
        <div ng-controller="MyController3">
            <div ng-controller="MyController4">
                <button id="myButton" ng-click="setMessage('second')">Press</button>
            </div>
        </div>
    </div>
    <script>
        angular.module('MyApp', [])
           .controller('MyController', function($scope) {
            $scope.myMessage = "First";
               $scope.setMessage = function(msg) {
                $scope.myMessage = msg;
               };
        }).controller('MyController2', function($scope) {

           }).controller('MyController3', function($scope) {

           }).controller('MyController4', function($scope) {

           });
    </script>

</div>
</div>

<div ng-app="MyApp">
<div ng-controller="MyController">
    {{myMessage}}
    <div ng-controller="MyController2">
        <div ng-controller="MyController3">
            <div ng-controller="MyController4">
                <button id="myButton" ng-click="setMessage('second')">Press</button>
            </div>
        </div>
    </div>
    <script>
        angular.module('MyApp', [])
           .controller('MyController', function($scope) {
            $scope.myMessage = "First";
               $scope.setMessage = function(msg) {
                $scope.myMessage = msg;
               };
        }).controller('MyController2', function($scope) {

           }).controller('MyController3', function($scope) {

           }).controller('MyController4', function($scope) {

           });
    </script>

</div>
</div>


{{myMessage}}
按
angular.module（'MyApp'，[]）
.controller（'MyController'，函数（$scope）{
$scope.myMessage=“第一”；
$scope.setMessage=函数（msg）{
$scope.myMessage=msg；
};
}).controller（'MyController2'，函数（$scope）{
}).controller（'MyController3'，函数（$scope）{
}).controller（'MyController4'，函数（$scope）{
});

<div ng-app="MyApp">
<div ng-controller="MyController">
    {{myMessage}}
    <div ng-controller="MyController2">
        <div ng-controller="MyController3">
            <div ng-controller="MyController4">
                <button id="myButton" ng-click="setMessage('second')">Press</button>
            </div>
        </div>
    </div>
    <script>
        angular.module('MyApp', [])
           .controller('MyController', function($scope) {
            $scope.myMessage = "First";
               $scope.setMessage = function(msg) {
                $scope.myMessage = msg;
               };
        }).controller('MyController2', function($scope) {

           }).controller('MyController3', function($scope) {

           }).controller('MyController4', function($scope) {

           });
    </script>

</div>
</div>

或者你可以使用angular$broadcast

我应该添加，我知道我可以通过将函数添加到作用域来实现这一点，我不想这样做。嗯。。。这是大量的

$parent

遍历。正如我在问题中所说的，我不想将这个模板绑定到那个特定的控制器。我希望它能被多个控制器使用。我通常对所有控制器使用统一的别名，因此，如果您对使用相同名称的类似控制器使用别名没有问题，这种方法就可以工作。否则，您应该直接将您的方法公开给$scope，或者按照Ravi的建议使用$scope.broadcast。这将使嵌套控制器非常困难。我将尝试广播

<div ng-app="MyApp">
<div ng-controller="MyController">
    {{myMessage}}
    <div ng-controller="MyController2">
        <div ng-controller="MyController3">
            <div ng-controller="MyController4">
                <button id="myButton" ng-click="setMessage('second')">Press</button>
            </div>
        </div>
    </div>
    <script>
        angular.module('MyApp', [])
           .controller('MyController', function($scope) {
            $scope.myMessage = "First";
               $scope.setMessage = function(msg) {
                $scope.myMessage = msg;
               };
        }).controller('MyController2', function($scope) {

           }).controller('MyController3', function($scope) {

           }).controller('MyController4', function($scope) {

           });
    </script>

</div>
</div>
