angularjs在控制器之间共享数据配置

angularjs

我想知道什么是在控制器之间共享指令的好方法。我有两个指令要在具有不同配置的不同控制器中使用,首先想到的是我想到的使用方法:

//html
<body data-ng-controller="MainCtrl">
    <div class="container">
        <div data-ui-view></div>
    </div>
</body>

//js
.controller('MainCtrl', function ($scope,$upload) {
    /*File upload config*/
    $scope.onFileSelect = function($files) {
        for (var i = 0; i < $files.length; i++) {
          var file = $files[i];
          $scope.upload = $upload.upload({
                url: 'server/upload/url', 
                method: 'POST',
                data: {myObj: $scope.myModelObj},
                file: file,
          }).progress(function(evt) {
            console.log('percent: ' + parseInt(100.0 * evt.loaded / evt.total));
          }).success(function(data, status, headers, config) {

            console.log(data);
          });

        }
    };
    /* Datepicker config */
    $scope.showWeeks = true;
    $scope.minDate = new Date();
    $scope.open = function($event) {
        $event.preventDefault();
        $event.stopPropagation();
        $scope.opened = true;
    };
    $scope.dateOptions = {
        'year-format': "'yy'",
        'starting-day': 1
    };
    $scope.format = 'MMM d, yyyy';
})
.controller('IndexCtrl', function ($scope) {

})

这样,我可以使用子控制器中的所有功能,但是由于碰撞问题,我不太喜欢。由于您不能使用服务(不能在服务中使用$
scope),其他选择可以是其他指令或将代码放入运行块,但使用父控制器则完全相同,因此您怎么看? ?

更新

您如何看待这种方法?

//outside of angular stauff
function MyTest(){
    this.testScope = function(){
        console.log('It works');
    }
}

//inside a controller
$scope.ns = new MyTest();

//in the view
<p ng-click="ns.testScope()">ppp</p>

RIUPDATE这似乎是最好的选择:)

MyTest.call($scope);

考虑一下本文描述的方法:使用Mixin模式扩展AngularJS控制器

不要将方法从服务中复制出来,而是创建一个包含这些方法的基本控制器,然后在派生的控制器上调用extend来将它们混合使用。

function AnimalController($scope, vocalization, color, runSpeed) {

    var _this = this;

    // Mixin instance properties.
    this.vocalization = vocalization;
    this.runSpeed = runSpeed;

    // Mixin instance methods.
    this.vocalize = function () {
        console.log(this.vocalization);
    };

    // Mixin scope properties.
    $scope.color = color;

    // Mixin scope methods.
    $scope.run = function(){
        console.log("run speed: " + _this.runSpeed );
    };
}

现在我们可以将AnimalController混入DogController中:

function DogController($scope) {

    var _this = this;

    // Mixin Animal functionality into Dog.
    angular.extend(this, new AnimalController($scope, 'BARK BARK!', 'solid black', '35mph'));

    $scope.bark = function () {
        _this.vocalize(); // inherited from mixin.
    }
}

然后在我们的模板中使用DogController:

<section ng-controller="DogController">
    <p>Dog</p>

    <!-- Scope property mixin, displays: 'color: solid black' -->
    <p ng-bind-template="color: {{ color }}"></p>

    <!-- Calls an instance method mixin, outputs: 'BARK BARK!' -->
    <button class="btn" ng-click="bark()">Bark Dog</button>

    <!-- Scope method mixin, outputs: 'run speed: 35mph' -->
    <button class="btn" ng-click="run()">Run Dog</button>
</section>

此示例中的控制器全部位于全局空间中,并包含在标记中,如下所示。

<script type="text/javascript" src="lib/jquery.js"></script>
<script type="text/javascript" src="lib/angular.js"></script>
<script type="text/javascript" src="app/controllers/animal-controller.js"></script>
<script type="text/javascript" src="app/controllers/dog-controller.js"></script>
<script type="text/javascript" src="app/controllers/cat-controller.js"></script>
<script type="text/javascript" src="app/app.js"></script>

我还没有测试过,但是我不明白为什么下面的方法不起作用:

var myApp = angular.module('myApp', [])

.controller('AnimalController', ['$scope', 'vocalization', 'color', 'runSpeed', function ($scope, vocalization, color, runSpeed) { /* controller code here */}]);

.controller('DogController', ['$scope', '$controller', function($scope, $controller) {
    var _this = this;

    // Mixin Animal functionality into Dog.
    angular.extend(this, $controller('AnimalController', {
         $scope: scope,
         vocalization: 'BARK BARK!', 
         color: 'solid black', 
         runSpeed:'35mph' 
    }));

    $scope.bark = function () {
        _this.vocalize(); // inherited from mixin.
    }
}]);
