我将使用dataSource作为数组的材质数据表。
import { Component, OnInit } from '@angular/core';
import { MatTableDataSource } from '@angular/material';
import { AjouttextService } from '../ajouttext.service';
import { DataSource } from "@angular/cdk/collections";
import { Observable } from "rxjs/Observable";
import { nomchamp } from '../model';
@Component({
selector: 'app-datatable',
templateUrl: './datatable.component.html',
styleUrls: ['./datatable.component.css']
})
export class DatatableComponent implements OnInit {
constructor(private dataService: AjouttextService) { }
data: nomchamp[] = [{ id: "33", text: "HAHA" }, { id: "55", text: "bzlblz" }];
displayedColumns = ['text'];
dataSource = this.data;
applyFilter(filterValue: string) {
filterValue = filterValue.trim(); // Remove whitespace
filterValue = filterValue.toLowerCase(); // MatTableDataSource defaults to lowercase matches
}
ngOnInit() {
}
}
当我运行我的应用程序时,我在html文件中遇到此错误,第2行:
错误类型错误:this.dataSource.connect不是函数
这里的html文件:
<div class="example-container mat-elevation-z8">
<mat-table #table [dataSource]="dataSource">
<!-- Position Column -->
<ng-container matColumnDef="text">
<mat-header-cell *matHeaderCellDef> No. </mat-header-cell>
<mat-cell *matCellDef="let element"> {{element.text}} </mat-cell>
</ng-container>
<mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>
<mat-row *matRowDef="let row; columns: displayedColumns;"></mat-row>
</mat-table>
</div>
答案 0 :(得分:4)
请参阅one of the examples from the docs。
您需要以这种方式实例化MatTableDataSource
:
dataSource = new MatTableDataSource(yourDataArray);
在您的情况下,您还可以添加类型信息:
dataSource = new MatTableDataSource<nomchamp>(yourDataArray);
