Eliminar datos del marcador de posición api json Angler

Estoy tratando de eliminar el td en el que se hizo clic con el anguler, pero no funciona, no devuelve nada, solo obtiene los datos. ¿Alguien podría ayudarme y decirme dónde está mi error? Soy nuevo en el uso del anguler. gracias aquí es componente.ts

 import { Component, OnInit } from '@angular/core'; import {HttpClient} from '@angular/common/http' @Component({ selector: 'app-home', templateUrl: './home.component.html', styleUrls: ['./home.component.css'] }) export class HomeComponent implements OnInit { dataArray; id; constructor( private http:HttpClient) { this.http.get('https://jsonplaceholder.typicode.com/posts').subscribe( data =>{ this.dataArray = data } ) } ngOnInit(): void { this.delete } delete () { this.http.delete('https://jsonplaceholder.typicode.com/posts/${id}') .subscribe(() => this.id = 'Delete successful'); console.log(this.dataArray) } }

aquí está mi tabla:

 <div class="table-list"> <table class="table"> <thead> <tr> <th scope="col">Title</th> <th scope="col">Operations</th> </tr> </thead> <tbody> <tr *ngFor="let item of dataArray;" index as i> <td>{{item.title}}</td> <td> <i class="fal fa-check-circle px-2"></i> <i class="fal fa-edit px-2"></i> <button><i class="fal fa-trash-alt" (click)="delete()"></i></button> </td> </tr> </tbody> </table>

Tienes que pasar un parámetro a tu función de eliminación:

 delete (id: number) { this.http.delete('https://jsonplaceholder.typicode.com/posts/' + id) .subscribe(() => this.id = 'Delete successful'); console.log(this.dataArray)

}

En su html, agregue (click)="delete(item.id)

Luego, para eliminar los datos de la matriz, debe ejecutar:

 this.array = this.array.filter((d) => d.id !== id));
