如果在从服务器获取数据时,Angular Material表中的过滤器不起作用,可能是因为过滤器的实现不正确或者数据没有正确绑定到表格中。以下是一个可能的解决方案,其中包含代码示例:
import { MatTableDataSource } from '@angular/material/table';
import { MatPaginator } from '@angular/material/paginator';
import { MatSort } from '@angular/material/sort';
import { ViewChild } from '@angular/core';
import { HttpClient } from '@angular/common/http';
export class YourComponent {
dataSource: MatTableDataSource;
displayedColumns: string[] = ['id', 'name', 'email'];
@ViewChild(MatPaginator) paginator: MatPaginator;
@ViewChild(MatSort) sort: MatSort;
constructor(private http: HttpClient) { }
ngOnInit() {
this.getDataFromServer();
}
getDataFromServer() {
this.http.get('your-api-url').subscribe((data: any[]) => {
this.dataSource = new MatTableDataSource(data);
this.dataSource.paginator = this.paginator;
this.dataSource.sort = this.sort;
});
}
}
ID
{{element.id}}
Name
{{element.name}}
Email
{{element.email}}
applyFilter(filterValue: string) {
this.dataSource.filter = filterValue.trim().toLowerCase();
}
通过以上步骤,你应该能够在从服务器获取数据时让Angular Material表中的过滤器起作用。确保在正确绑定数据源、排序和分页器之后,正确实现过滤器逻辑。
