当Angular Material Datatable加载慢时,可以尝试以下解决方法:
import { MatTableDataSource } from '@angular/material/table';
import { MatPaginator } from '@angular/material/paginator';
export class YourComponent {
dataSource = new MatTableDataSource();
@ViewChild(MatPaginator) paginator: MatPaginator;
ngOnInit() {
// 设置数据源
this.dataSource.data = yourDataArray;
// 将分页器和数据源关联
this.dataSource.paginator = this.paginator;
}
}
import { HttpClient, HttpParams } from '@angular/common/http';
export class YourComponent {
constructor(private http: HttpClient) {}
loadData(page: number, pageSize: number) {
const params = new HttpParams()
.set('page', page.toString())
.set('pageSize', pageSize.toString());
this.http.get('/your-api-url', { params }).subscribe(data => {
// 处理返回的数据
});
}
}
以上是一些常见的解决方法,可以根据具体情况选择适合的方法来优化Angular Material Datatable的加载速度。
