问题 I'm using ngx-translate library for translations. In my components (lazy loaded routes) When I set the following, it works fine: constructor( public translate:TranslateService ) { this.translate.setDefaultLang( this.langService.lang ); this.translate.use( this.langService.lang ); } I have my own LangService just to save user's selected language. I set it to lang property and use TranslateService there: lang:string = "fa"; constructor(public translate: TranslateService) { // this works console

问题 I've developed a component with two views. Component A has a contact form, and Component B is the "Thank you" page. Component A: You fill the form and submit it. As soon as the response arrives, a new ReplaySubject value is created. The user will be routed to the component B. Component B: The component is initialized. The component gets the value from the subject. The view is rendered and displays the thank you message. HTTP Call response (Returned after a successful Form data post request):

问题 I must be approaching this from a false perspective, but here is the problem. I have an async validation directive which uses HttpClient to validate something with the backend. It is almost independent apart from one critical thing – it needs correct HTTP headers to pass authentication on the server side. This is how the constructor looks: constructor( private http: HttpClient, private auth: AuthService, @Optional() @Self() @Inject(NG_VALUE_ACCESSOR) valueAccessors: ControlValueAccessor[] ) {

问题 I am testing a service function which makes numerous $http.get() calls. The actual function under test returns a promise. Currently, the test is failing with response is undefined . Here is the test: it('should return the list of catalogues', inject(function ($q, bookService) { var list; var deferred = $q.defer(); var promise = deferred.promise; promise.then(function (response) { list = response.success; // Cannot read property 'success' of undefined }); bookService.getCatalogues().then

问题 I am using the excellent Angular Translate ( $translate ) directive/service to deal with multiple Locale Languages and since I have multiple locale files I use the convenient $translateProvider.useStaticFilesLoader to load my translation files through a structure of localeAbbr.json, for example en.json , es.json , etc... I built a Plunker to show my open source project and that project uses the locale through Git raw files (pointing to the actual Github repository, meaning not local to the

问题 lets say I got this kind of method on a service: this.search = function (term) { var deferred = $q.defer(); Restangular.all('search').getList(params) .then(_onRestResult.bind(this, deferred)) .catch(_onRestError.bind(this, deferred)); return deferred.promise; } function _onRestResult(deferred, data) { // notice it isn't on the this //doSomthing } But running a basic test. when I change the then clause to an anonymous function, everything works as expected, but when I used the named private

问题 I want my application to make Ajax Calls to a RESTful Webservice. In my html document are two textboxes that are connected to a scope object. Both fields are connected to the "post" function via ng-change. The post method sends the "form" variable from the scope to the API and the webservice adds both numbers and responds with a json file, which now contains the result. (This might not be very RESTful but it works for me) It works perfectly fine as long as I have the Ajax call in my

问题 I am trying to figure out or to make my services to get the correct url on event.the case is that I have a template with multiple tab and each one display a set of data on event binding , this is what it looks like : <div class="card-tabs"> <ul materialize="tabs" class="tabs tabs-fixed-width" (click)='select()'> <li class="tab"><a class="active" href="#west (click)='west()'>{{Department[0]}}</a></li> <li class="tab"><a href="#center" (click)='center()'>{{Department[1]}}</a></li> </ul> </div>

问题 I am trying to access the Angular Service Object (I have set the AuthContext in service) but Angular Guard is giving undefined even though that is well set. I have login component, which I call first and internally It uses the Angular Auth Service. In the constructor of that service, I ensure that AuthContext is well set. Through the debug, I have seen that object is available with all the required claims. But then when I access the regular component (which I have guarded through the Auth
