Im trying to iterate over an array but the dom is displaying [ object Object] instead. In other threads some people recommended to use Stringify and then it display the info but I can't iterate over a string. Thanks for your help.
Here is my code:
html
<div *ngFor="let price of prices">
{{prices}}
</div>
service.ts
import { Injectable } from '@angular/core';
import { Http, Headers, Response } from '@angular/http';
import 'rxjs/add/operator/toPromise';
import {Observable} from "rxjs";
import 'rxjs/Rx';
import 'rxjs/add/operator/catch';
import { MarketViewModel } from '../comprarmonedas/datosmoneda'
@Injectable()
export class BittrexService {
constructor(private http: Http, private marketModel : MarketViewModel) { }
public getPrices() :Observable<MarketViewModel> {
return this.http.get('https://bittrex.com/api/v1.1/public/getmarketsummary?market=btc-zec')
.map((response: Response) => response.json());
}
}
interface
export class MarketViewModel {
public success : boolean;
public message : string;
public result : MarketListObject[];
}
export class MarketListObject {
public MarketName : string;
public High : number;
public Low : number;
public Volume : number;
public Last : number;
public BaseVolume : number;
public TimeStamp : number;
public Bid : number;
public Ask : number;
public OpenBuyOrders : number;
public OpenSellOrders : number;
public PrevDay : number;
public Created : number;
}
component.ts
import { Component, OnInit } from '@angular/core';
import { Http, Response, Headers } from '@angular/http';
import { BittrexService } from '../../bittrex/bittrex.service';
import {Observable} from "rxjs";
@Component({
selector: 'app-comprarzec',
templateUrl: './comprarzec.component.html',
styleUrls: ['./comprarzec.component.scss']
})
export class ComprarzecComponent implements OnInit {
private prices = [];
constructor(private bittrexService: BittrexService) {
this.bittrexService = bittrexService;
}
ngOnInit(){
this.bittrexService.getPrices()
.subscribe(
data => this.prices = data.result
);
}
}
