问题
I am new to AngularJS and I used ncy-breadcrumb for my AngularJS project. There is an abstract true parent state and two child states of it. I used these child states for tabs. But I couldn't find a way to show these states in the breadcrumb dynamically. The only thing I can do is hardcode one child state name as parent in other state. But I need a solution to display these child states in collectionsWorkPage
state dynamically.
.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;
}
}
})
回答1:
app.config(['$breadcrumbProvider', configNcyBreadcrumb])
function configNcyBreadcrumb($breadcrumbProvider) {
$breadcrumbProvider.setOptions({
includeAbstract : true
});
}
回答2:
The parent
property can be either a string or a function returning the parent name. The function provides the scope of the current state controller (the same used for labels interpolation).
So you can do something like this:
ncyBreadcrumb: {
label: 'Edit Collection',
parent: function($scope) {
if($scope.tab === 'MY') // Constant defined in CollectionsLibraryMyController
return 'collectionsLibrary.my';
else if($scope.tab === 'AVAILABLE') // Constant defined in CollectionsLibraryAvailableController
return 'collectionsLibrary.available';
}
}
See API reference for more details
