subscribe

问题 I'm trying to test ngOnInit() method for the component that has a subscribe method: Component: import { Component, OnInit} from '@angular/core'; import { SharedDataService } from './../services/shared-data.service'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.scss'] }) export class AppComponent implements OnInit { constructor(private sharedDataService: SharedDataService,) { } this.subscriptions = []; ngOnInit() { this.subscriptions.push

问题 In my component I have a save function like below: save() { var result; //For updating task if (this.task.AllTaskId) { if (this.task.AssignedToCode == null) { this.task.AssignedToCode = "All"; } this.task.CreatedDate = new Date(); this.task.CreatedBy = this.empcode; result = this._tasksService.updateTask(this.task).subscribe( res => { this._router.navigate(['/regtask']) } ) } //For Adding new task else { if (this.task.AssignedToCode == null) { this.task.AssignedToCode = "All"; } this.task

问题 I am looking for a java code for MQTT client that subscribes to a given topic, every message published on that topic should reach the client only once.I have written many codes and in all the cases messages are delivered properly to the client when it is connected to the broker but if the subscribed client disconnects from the broker for some time and then again connects back, it does not receive the messages that were sent during the time that it was not connected and I have set the clean

问题 I wonder if I am using Observable.subscribe() too many times or not. In my component class, I have a function loadData(). It calls another function this.service.getData() that uses HttpClient.get() to perform a HTTP request to the server. Currently in my function loadData(), I subscribe to the result of this.service.getData(). Each time the user clicks on a "Update" button, I would like to call my function loadData(). The question If I call my function loadData() every time I need to perform

问题 I'm trying to test my front-end code without the back-end api using observables. In my component's template I have a textarea. Ultimately I need to send the textarea content to back-end api using http.post and receive back the validation for the content. In the constructor of my component.ts I define an observable which does some very basic checks and creates mock results after a timeout of 2000ms (like http.post/http.get): private obsVal: Observable < any >; private obsChange: Observable <

问题 I have 2 C# classes one of them has a string delegate and the other subscribes an function to that delegate. My question is I want to combine the two called string functions from the delegate instead of choosing the return value between them randomly delgatesystem.cs: using System.Collections; using System.Collections.Generic; using UnityEngine; public class delegatesystem : MonoBehaviour { public delegate string MyDelegate(); public static event MyDelegate MyEvent; string GameObjectsNames =

问题 I'm trying to do multiple ajax calls together. I can't figure out what is wrong with these lines. Seems like the second input of the subscribe function is processed as Group[] instead of Authorization[] Observable.forkJoin( [this.userService.getAllGroups(),this.userService.getAllAuthorizations()] ) .subscribe( ([groups,authorizations]) => { this.groups = groups; this.authorizations = authorizations; //error: Type 'Group[]' is not assignable to type 'Authorization[]' this.loaderService

问题 I have started to use Mailjet to store the subscription emails using a form. The library I used for this task is "https://github.com/mailjet/mailjet-apiv3-php-simple" include("php-mailjet-v3-simple.class.php"); $apiKey = "xxx"; $secretKey = "yyy"; $mj = new Mailjet($apiKey, $secretKey); $contact_params = array("method" => "POST", "Email" => "abc@gmail.com"); $contact = $mj->contact($contact_params); $add_params = array( "method" => "POST", "ListID" => "11223344", "IsActive" => "True" );

问题 Did I understood correctly that you can't subscribe to an event other than using the VBA Editor's control name + event name comboboxes? There is no combobox.change+=eventhandler syntax available as in other languages like C#, is there? 回答1: Correct. Event handling is done via naming convention in VB6/VBA. The name can be the name of the control itlsef, or it can be a variable declared WithEvents . By assigning this variable a different reference, you start receiving events from that new
