【问题描述】:
我是 Angular 新手,正在做一个示例项目,我想在网格中显示一些 JSON 数据。
我也在使用 ag-grid。 我从其他 API 获得以下 Json 响应:-
[
{
"id": 64,
"name": "Utopia",
"language": "English",
"genres": [
"Drama",
"Science-Fiction",
"Thriller"
],
"status": "Ended",
"image": {
"medium": "http://static.tvmaze.com/uploads/images/medium_portrait/0/474.jpg",
"original": "http://static.tvmaze.com/uploads/images/original_untouched/0/474.jpg"
}
},
{
"id": 65,
"name": "Bones",
"language": "English",
"genres": [
"Drama",
"Crime",
"Medical"
],
"status": "Ended",
"image": {
"medium": "http://static.tvmaze.com/uploads/images/medium_portrait/80/201202.jpg",
"original": "http://static.tvmaze.com/uploads/images/original_untouched/80/201202.jpg"
}
}
]
我能够成功绑定简单键的数据,如 id、名称、语言等,但在绑定嵌套对象时,我无法做到。
如果你看上面的 json 响应,'image' 字段是一个对象。如何从中获取 'medium' 或 'original' 键的值并在我的行中显示图像?
感谢您的帮助,因为这是我遇到的问题。
下面是我的组件代码:-
shows.component.ts
@Component({
selector: 'app-shows',
templateUrl: './shows.component.html',
styleUrls: ['./shows.component.css']
})
export class ShowsComponent implements OnInit {
public gridOptions: GridOptions;
public tvShowsColumnDefs = new ShowColumn;
public showMetaData: any;
constructor(private _contentService: ContentService, private _router: Router,
private _route: ActivatedRoute) {
// GridOptions Initialized
this.gridOptions = <GridOptions>{};
this.gridOptions.columnDefs = this.tvShowsColumnDefs.columnDefs;
}
ngOnInit() {
// Prepare Grid Row Data
this.prepareRowData();
}
prepareRowData() {
// API Call for getting TV-Shows
this._contentService.getAllShows()
.subscribe(response => {
const shows = response;
console.log('TVShows-API Response ', shows);
// Setting Grid RowData using api response
this.gridOptions.api.setRowData(shows);
});
}
show.columnDef.ts
export class ShowColumn {
public columnDefs = [
{ field: 'id', headerName: '', width: 50 },
{ field: 'image', headerName: '', width: 50, cellRendererFramework: null},
{ field: 'name', headerName: '', width: 250},
{ field: 'language', headerName: 'Language', width: 100},
{ field: 'genres', headerName: 'Genres', width: 250},
{ field: 'status', headerName: 'Status', width: 145 }
];
constructor() { }
}
