如何在抽象父级的子状态中使用ncy-breadcrumb

标签: javascript angularjs angular-ui-router ncybreadcrumb

我是AngularJS的新手,我使用ncy-breadcrumb作为我的AngularJS项目。有一个抽象的真正的父状态和它的两个子状态。我使用这些子状态作为标签。但我无法找到一种方法来动态显示面包屑中的这些状态。我唯一能做的就是将一个子状态名称硬编码为其他状态的父级。但我需要一个解决方案来动态显示collectionsWorkPage状态的这些子状态。

.state('collectionsLibrary', {
   url: '/headquarters/collections-library/',
   templateUrl: 'app/views/collectionsLibrary/base.html',
   controller: 'CollectionsLibraryBaseController',
   ncyBreadcrumb: {
      label: 'Collections Library',
      parent: 'headquarters'
   },
   abstract: true,
   resolve: {
      controller: function ($q) {
         var deferred = $q.defer();
         require(['controllers/collectionsLibrary/CollectionsLibraryBaseController'], function () {
            deferred.resolve();
         });
         return deferred.promise;
      }
   }
   })

.state('collectionsLibrary.available', {
   url: 'available/',
   templateUrl: 'app/views/collectionsLibrary/available.html',
   controller: 'CollectionsLibraryAvailableController',
   ncyBreadcrumb: {
      label: 'Collections Library-Available',
      parent: 'headquarters'
   },
   resolve: {
      controller: function ($q) {
         var deferred = $q.defer();
         require(['controllers/collectionsLibrary/CollectionsLibraryAvailableController'], function () {
            deferred.resolve();
         });
         return deferred.promise;
      }
   }
})

.state('collectionsLibrary.my', {
   url: 'my/',
   templateUrl: 'app/views/collectionsLibrary/my.html',
   controller: 'CollectionsLibraryMyController',
   ncyBreadcrumb: {
      label: 'Collections Library-My',
      parent: 'headquarters'
   },
   resolve: {
      controller: function ($q) {
         var deferred = $q.defer();
         require(['controllers/collectionsLibrary/CollectionsLibraryMyController'], function () {
            deferred.resolve();
         });
         return deferred.promise;
      }
   }
})

.state('collectionsWorkPage', {
   url: '/headquarters/collections-library/:id/edit/',
   templateUrl: 'app/views/collectionsWorkPage.html',
   controller: 'CollectionsWorkPageController',
   ncyBreadcrumb: {
      label: 'Edit Collection',
      parent: 'collectionsLibrary.available'
   },
   params: {
      data: {}
   },
   resolve: {
      controller: function ($q, $stateParams) {
         var deferred = $q.defer($stateParams);
         require(['controllers/CollectionsWorkPageController'], function () {
            deferred.resolve();
         });
         return deferred.promise;
      }
   }
})

app.config(['$breadcrumbProvider', configNcyBreadcrumb])

function configNcyBreadcrumb($breadcrumbProvider) {
    $breadcrumbProvider.setOptions({
        includeAbstract : true
    });
}

parent属性可以是字符串,也可以是返回父名称的函数。该函数提供了当前状态控制器的范围(与标签插值相同)。

所以你可以这样做:

ncyBreadcrumb: {
  label: 'Edit Collection',
  parent: function($scope) {
    if($scope.tab === 'MY') // Constant defined in CollectionsLibraryMyController
      return 'collectionsLibrary.my';
    else if($scope.tab === 'AVAILABLE') // Constant defined in CollectionsLibraryAvailableController
      return 'collectionsLibrary.available';
  }
}
