我正在try 通过切片我的数据数组来向我的Angular 10.1.0项目添加翻页.然而，我得到了TS2339: Property 'slice' does not exist on type 'WritableSignal<Data[]>'错误.
以下是我的组件的摘录:
export class Component implements OnInit {
data = signal<Data[]>([]);
currentPage: number = 1;
constructor(private httoService: HttpService) {}
ngOnInit(): void {
this.fetchData();
}
fetchData(): void {
this.httpService.getData().subscribe((data) => {
this.data.set(data);
});
}
get paginatedData() {
const start = (this.currentPage - 1) * 100;
const end = start + 100;
return this.data.slice(start, end);
}
...
}
我的http.service.ts:
export class HttpService {
http = inject(HttpClient);
private apiUrl = 'url'
getProducts(): Observable<Data[]> {
return this.http.get<Data[]>(this.apiUrl);
}
}
我try 在切片之前提取值:
const dataArray = Array.from(this.data().values)
但它返回0.
