要解决Angular Material的数据表过滤和分页与来自REST API的数据不起作用的问题,可以按照以下步骤进行:
import { MatTableModule } from '@angular/material/table';
import { MatPaginatorModule } from '@angular/material/paginator';
import { MatSortModule } from '@angular/material/sort';
@NgModule({
imports: [
MatTableModule,
MatPaginatorModule,
MatSortModule,
// other modules
],
// other configurations
})
export class AppModule { }
import { Component, OnInit, ViewChild } from '@angular/core';
import { MatTableDataSource } from '@angular/material/table';
import { MatPaginator } from '@angular/material/paginator';
import { MatSort } from '@angular/material/sort';
@Component({
selector: 'app-my-component',
templateUrl: './my-component.component.html',
styleUrls: ['./my-component.component.css']
})
export class MyComponent implements OnInit {
dataSource: MatTableDataSource;
displayedColumns: string[] = ['column1', 'column2', 'column3'];
@ViewChild(MatPaginator, { static: true }) paginator: MatPaginator;
@ViewChild(MatSort, { static: true }) sort: MatSort;
ngOnInit() {
this.getDataFromApi(); // 从REST API获取数据
}
getDataFromApi() {
// 使用HttpClient从REST API获取数据
// 假设返回的数据是一个对象数组,每个对象都包含column1、column2和column3属性
this.httpClient.get('api/data').subscribe((data: any[]) => {
this.dataSource = new MatTableDataSource(data);
this.dataSource.paginator = this.paginator;
this.dataSource.sort = this.sort;
});
}
applyFilter(filterValue: string) {
this.dataSource.filter = filterValue.trim().toLowerCase();
}
}
Column 1
{{element.column1}}
Column 2
{{element.column2}}
Column 3
{{element.column3}}
通过以上步骤,你就可以实现Angular Material的数据表过滤和分页与来自REST API的数据的交互作用了。
