Mengapa array hanya membawa satu objek dalam proyek Angular?

Question

Saya bekerja dengan League of Legends API, lebih spesifik dengan champion json yang mereka bawa.

Saya memiliki layanan ini yang dibuat dengan Angular:

import { Injectable } from '@angular/core';
import { HttpClient, HttpHeaders} from '@angular/common/http';

const httpOptions = {
  headers: new HttpHeaders({'Content-Type': 'application/json'})
}

@Injectable({
  providedIn: 'root'
})
export class ChampionsService {

  constructor(private http: HttpClient) { }

  getChampions(){
    return this.http.get('http://ddragon.leagueoflegends.com/cdn/10.23.1/data/es_ES/champion.json');
  }

}

Ini file .ts saya:

import { Component, OnInit } from '@angular/core';
import {ChampionsService } from '../../services/champions.service';

@Component({
  selector: 'app-champions',
  templateUrl: './champions.component.html',
  styleUrls: ['./champions.component.css']
})

export class ChampionsComponent implements OnInit {

  public champions;
  public arrayChampions;
  
  
  constructor(private championsService:ChampionsService) { }

  ngOnInit(): void {
    this.getAllChampions();
  }

  getAllChampions(){
    this.championsService.getChampions().subscribe(
      data => { this.champions = data, 
        this.arrayChampions = Object.entries(this.champions.data).map(([k,v]) => ({ [k]:v })),
        this.ArrayIterator(); 
      },
      err => {console.error(err)},
      () => console.log("Champions cargados")
    );
  }

  ArrayIterator() {
    let IteratableArray = Array();
    for (let item of Object.keys(this.arrayChampions[0])) {
      var eventItem = Object.values(this.arrayChampions[0]);
      IteratableArray.push(eventItem);
    }
    this.arrayChampions = IteratableArray[0];
  }
}

Dan ini html-nya:

<p>champions works!</p>
{{arrayChampions | json}}
 <!-- Cards -->
<div *ngFor="let arrayChampion of arrayChampions" class="card mb-3">
    <div class="card-header">
    </div>
    <div class="card-body">
        <blockquote class="blockquote mb-0">
            <a class="text-decoration-none">{{arrayChampion.id}}</a>
        </blockquote>
    </div>
    <div class="card-footer">
    </div>
</div>

Seperti yang Anda lihat, var "arrayChampions" hanya membawa juara pertama (Atrox) ketika harus membawa semua juara seperti yang saya mengerti (saya baru di javascript dan Angular).

Answer 1

Sesuai contoh Anda, saya telah membuat dan menumpuk blitz di sini, Dan itu membuat seluruh arrayChampionsIterasi di atas nilainya.

Contoh HTML:

<hello name="{{ name }}"></hello>
<!-- {{this.products |json}} -->
<ul>
    <li *ngFor="let champ of products | keyvalue">
        <label style="font-size: 20px;font-weight: bold;color: red;">
      {{champ.key}}
    </label>
        <ul *ngFor="let item of champ.value | keyvalue">
            <li>
                {{item.key}} : {{item.value}}
                <ul *ngFor="let sub of item.value | keyvalue">
                    <li>
                        {{sub.key}} : {{sub.value}}
                    </li>
                </ul>
            </li>
        </ul>
    </li>
</ul>

Sample component.ts:

import { Component } from "@angular/core";
import { HttpClient } from "@angular/common/http";
import { map, catchError, tap } from "rxjs/operators";

@Component({
  selector: "my-app",
  templateUrl: "./app.component.html",
  styleUrls: ["./app.component.css"]
})
export class AppComponent {
  apiURL: string =
    "https://ddragon.leagueoflegends.com/cdn/10.23.1/data/es_ES/champion.json";
  name = "Angular";
  products = [];

  constructor(private httpClient: HttpClient) {}

  ngOnInit() {
    this.getChamp();
  }

  getChamp() {
    this.httpClient.get(this.apiURL).subscribe((data: any) => {
      this.products = data.data;
      Object.keys(data.data).map((key: any, obj: any) => obj[key]);
    });
  }
}
