我想用以下代码在按钮点击后显示获取到的电影标题:
import {Component} from '@angular/core';
import {Http, Response} from '@angular/http';
@Component({
selector: 'http',
template: `
<button (click)="makeRequest()">Make Request</button>
<table class="table table-striped">
<thead>
<tr>
<th>Title</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let movie of data">
<td>{{movie.title}}</td>
</tr>
</tbody>
</table>
`
})
export class AppComponent {
data: Object;
constructor(public http: Http) {
}
makeRequest(): void {
this.http.request('http://api.themoviedb.org/3/movie/top_rated?api_key=API-KEY')
.subscribe((res: Response) => {
this.data = res.json();
});
}
}
我的问题是,我收到一个错误消息,提示我只能循环遍历数组,而我的数据是一个对象。 在Typescript中如何将我的对象转换为数组,并在表格中显示电影的标题?
