【问题描述】:
我正在尝试使用 Angular2 ng 智能表插件将数据从我的 API 加载到自定义组件。
我的组件如下:
import { LocalDataSource } from 'ng2-smart-table';
import { ProductService } from '../../../services/product.service';
export class CategoryItemsComponent implements OnInit {
...
source: LocalDataSource;
constructor(private productService: ProductService,
private flashMessage: FlashMessagesService,
private router: Router,
http: Http) {
this.source = new LocalDataSource();
this.productService.getProductsOncategory(this.categoryid).subscribe((data) => {
this.source.load(data);
});
}
产品服务 .ts
getProductsOncategory(category_id) {
let catUrl = "http://localhost:5000/products/getProductsOncategory"
let headers = new Headers();
headers.append('Content-Type', 'application/json');
let catIdObj = JSON.stringify({ category_id: category_id })
return this.http.post(catUrl, catIdObj, { headers: headers })
.map((response: Response) => response.json())
.do(data => console.log(JSON.stringify(data)))
.catch(this.handleError);
}
服务功能中使用的上述API在我的邮递员中完美运行。
现在我需要将该 API 中的 dame 数据加载到我的自定义组件中。
我收到此错误:
错误 TypeError: this.data.slice 不是函数
