绑定不显示对象属性

Question

我想在HTML中显示一些属性。当Angular绑定它所显示的属性时，问题是透明的。 当我调试时，变量“vm.cancha”从另一个控制器接收数据：

控制器：

(function() {
'use strict';

angular
    .module('example.infocancha')
    .controller('InfoCanchaController', InfoCanchaController);

InfoCanchaController.$inject = ['$stateParams'];

function InfoCanchaController($stateParams) {
    var vm = this;
    vm.cancha = [];
    vm.obtenerInformacionCancha, obtenerInformacionCancha;

    inicializar();

    function inicializar() {
        obtenerInformacionCancha();

    }

    //funcion para obtener la cancha seleccionada
    function obtenerInformacionCancha() {
        vm.cancha =  angular.fromJson($stateParams.cancha);
        debugger;
    }
}
})();

查看：

<ion-view view-title="{{cancha.nroCancha}}">
<ion-content>

    <h3 class="content-horizontal-padding">{{cancha.descripcion}}</h3>
    <div class="list card">
        <a class="item item-icon-left">
            <i class="icon ion-email"></i>
            {{cancha.descripcion}}
        </a>

    </div>

</ion-content>
</ion-view>

同样在我的示例模块中，我有：

(function() {
'use strict';

angular
    .module('example.infocancha', [
        'ionic',
        'ngCordova',
        'example.comun'
    ])
    .config(function($stateProvider) {
        $stateProvider
            .state('app.example', {
                url: '/example/examplecancha/:cancha',
                views: {
                    'menuContent': {
                        templateUrl: 'scripts/example/examplecancha/example.html',
                        controller: 'InfoCanchaController as vm'
                    }
                }
            });
    });
})();

你能告诉我为什么绑定没有显示任何内容？ 谢谢！

Answer 1

You have used controllerAs syntax. 

ng-controller = "InfoCanchaController as ct" 
// when you use controllerAs syntax, you are doing $scope.ct = vm = this;

{{ct.cancha.descripcion}}

//when you are injecting $scope in controller, you are attaching data to it directly. 
//In this case it will work as, you are doing $scope.cancha.descripcion = something. 
{{cancha.descripcion}}
