.ts文件
import { Component, OnInit,ViewChild } from '@angular/core';
import { Subscription } from 'rxjs';
import { CardsInfoService } from '../cards-info.service';
import {MediaMatcher} from '@angular/cdk/layout';
import {ChangeDetectorRef, OnDestroy} from '@angular/core';
@Component({
selector: 'app-private',
templateUrl: './private.component.html',
styleUrls: ['./private.component.scss']
})
export class PrivateComponent implements OnInit,OnDestroy {
datasource=[];
subscription: Subscription;
mobileQuery: MediaQueryList;
private _mobileQueryListener: () => void;
constructor( media: MediaMatcher,
changeDetectorRef: ChangeDetectorRef,
private cardsInfo :CardsInfoService) {
this.mobileQuery = media.matchMedia('(max-width: 600px)');
this._mobileQueryListener = () => changeDetectorRef.detectChanges();
this.mobileQuery.addListener(this._mobileQueryListener);
}
ngOnDestroy(): void {
this.mobileQuery.removeListener(this._mobileQueryListener);
}
ngOnInit(){
this.cardsInfo.getCardsInfo()
.subscribe(
data => {
this.datasource = data;
});
}
}
如果需要,我会将代码添加到stackblitz中.

推荐答案
此答案总结了如何使 mat-paginator
在没有 mat-table
的情况下工作.以下是您或其他任何人将 mat-paginator
与其他元素/组件一起使用时需要进行的详细更改.
This answer sums up the key points on how to make mat-paginator
work without a mat-table
. Below are the detailed changes you or anyone else would need to make to use mat-paginator
with other elements/components.
您需要像这样在模板的底部添加 mat-paginator
:
You would need to add a mat-paginator
at the bottom of your template like this:
<mat-paginator [pageSizeOptions]="[5, 10, 25, 100]"></mat-paginator>
然后使用 ViewChild
在您的组件中访问它:
Then access it in your component with ViewChild
:
@ViewChild(MatPaginator) paginator: MatPaginator;
将其链接到 ngOnInit
中的数据源:
Link it to your datasource in ngOnInit
:
this.dataSource.paginator = this.paginator;
并重写绑定数据源的方式:
And rewrite how you bind your datasource:
obs: Observable<any>;
// Card is whatever type you use for your datasource, DATA is your data
dataSource: MatTableDataSource<Card> = new MatTableDataSource<Card>(DATA);
ngOnInit() {
this.obs = this.dataSource.connect();
}
然后像这样使用模板中的数据源:
And then use the datasource in your template like this:
<mat-card *ngFor="let card of obs | async">
<!-- display your data here -->
</mat-card>
可以找到带有
mat-paginator
的mat-card
的工作堆栈闪电战此处.
