Je reçois le message d'erreur de type "arguments attendus de type 0, mais j'ai obtenu 1" malgré le suivi de ce tutoriel sur un T . https://youtu.be/I317BhehZKM?t=57s
J'ai précisé:
newUserInfoComplete:boolean = false
mais je reçois l'erreur spécifiée ci-dessus sur <boolean>
dans cette ligne:
@Output() newUserInfoCompleteEvent = new EventEmitter <boolean> ();
De plus, si je omets simplement <boolean>
, j'obtiens cette erreur:
Argument of type 'boolean' is not assignable to parameter of type 'string'.
et this.NewUserInfoComplete est souligné ici:
this.newUserInfoCompleteEvent.emit(this.newUserInfoComplete);
Si vous voulez voter par vers, laissez une note sur la façon dont je peux améliorer ma question. Merci.
Voici mon composant:
import { Component, OnInit, Output } from '@angular/core';
import { slideToRight } from '../../../../router.animations';
import { Router, ActivatedRoute, UrlSegment } from '@angular/router';
import { EventEmitter } from 'protractor';
@Component({
selector: 'app-new-user-input',
templateUrl: './new-user-input.component.html',
styleUrls: ['./new-user-input.component.css'],
animations: [slideToRight()]
})
export class NewUserInputComponent implements OnInit {
newUserInfoComplete:boolean = false
@Output() newUserInfoCompleteEvent = new EventEmitter <boolean> ();
constructor(private router: Router, r: ActivatedRoute) {
r.url.subscribe((s: UrlSegment[]) => {
console.log("url", s); //https://vsavkin.com/angular-router-understanding-router-state-7b5b95a12eab
});
}
ngOnInit() {
}
sendNewUserInfoComplete(){
this.newUserInfoCompleteEvent.emit(this.newUserInfoComplete);
}
displaySibling() {
console.log(this.router);
this.router.navigate(['../', { outlets: { newuserorginfo: ['newuserorginfo'] } }])
}
closeBlade() {
this.router.navigate([{ outlets: { newuserinput: null } }]);
}
}
Essayez d’importer EventEmitter
depuis Angular au lieu de protractor
:
import { Component, OnInit, Output, EventEmitter } from '@angular/core';
import { Component, Output } from '@angular/core';
import { slideToRight } from '../../../../router.animations';
import { Router, ActivatedRoute, UrlSegment } from '@angular/router';
import { EventEmitter } from 'protractor';
@Component({
selector: 'app-new-user-input',
templateUrl: './new-user-input.component.html',
styleUrls: ['./new-user-input.component.css'],
animations: [slideToRight()]
})
export class NewUserInputComponent {
newUserInfoComplete = false;
@Output() newUserInfoCompleteEvent = new EventEmitter <boolean> ();
constructor(private router: Router, r: ActivatedRoute) {
r.url.subscribe((s: UrlSegment[]) => {
console.log("url", s);
});
}
sendNewUserInfoComplete(){
this.newUserInfoCompleteEvent.emit(!!this.newUserInfoComplete);
}
displaySibling() {
console.log(this.router);
this.router.navigate(['../', { outlets: { newuserorginfo: ['newuserorginfo'] } }])
}
closeBlade() {
this.router.navigate([{ outlets: { newuserinput: null } }]);
}
}

J'ai oublié de vérifier mes importations! Zut. J'utilisais PROTRACTORS eventemitter et non le noyau angulaire Eventemitter
