我已經成功實現了這無數次,但我必須在這裏丟失一些東西。我的ngOnInit()函數調用DataService並返回一個產品,如下所示。Angular 2:數據沒有出現在模板中
@Component({
selector: 'app-product-card',
templateUrl: './product-card.component.html',
styleUrls: ['./product-card.component.css']
})
export class ProductCardComponent implements OnInit {
product: Product;
constructor(private dataService: DataService, private route:
ActivatedRoute) { }
ngOnInit() {
this.getProduct();
}
getProduct() {
this.route.params.subscribe(params => {
let id = params["id"];
this.dataService.getProduct(id).subscribe((product: Product) => {
this.product = product;
console.log("ProductCardComponent.product = " +
JSON.stringify(this.product));
})
})
}
}
但產品未在模板中顯示:
<div class="container-fluid">
<div class="col-sm-12">
<div *ngIf="product">
<div class="col-sm-1"></div>
<div class="col-sm-5">
<p>{{product.name}}</p>
<p>{{product.price}}</p>
</div>
<div class="col-sm-5">
fadfasdfadfasdf
</div>
</div>
</div>
</div>

在此聲明中記錄到控制檯的是什麼? console.log(「ProductCardComponent.product =」+ JSON.stringify(this.product)); – cobolstinks
是否已達到console.log行? –
達到了console.log。該產品已記錄到控制檯。 – koque
