【问题描述】：
我正在尝试实现 Angular Material 2，MatPaginator 服务器端分页。我怎样才能做到这一点？
下面是代码示例：
<div class="example-container mat-elevation-z8">
<mat-table #table [dataSource]="dataSource">
<!-- Position Column -->
<ng-container matColumnDef="position">
<mat-header-cell *matHeaderCellDef> No. </mat-header-cell>
<mat-cell *matCellDef="let element"> {{element.position}} </mat-cell>
</ng-container>
<!-- Name Column -->
<ng-container matColumnDef="name">
<mat-header-cell *matHeaderCellDef> Name </mat-header-cell>
<mat-cell *matCellDef="let element"> {{element.name}} </mat-cell>
</ng-container>
<!-- Weight Column -->
<ng-container matColumnDef="weight">
<mat-header-cell *matHeaderCellDef> Weight </mat-header-cell>
<mat-cell *matCellDef="let element"> {{element.weight}} </mat-cell>
</ng-container>
<!-- Symbol Column -->
<ng-container matColumnDef="symbol">
<mat-header-cell *matHeaderCellDef> Symbol </mat-header-cell>
<mat-cell *matCellDef="let element"> {{element.symbol}} </mat-cell>
</ng-container>
<mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>
<mat-row *matRowDef="let row; columns: displayedColumns;"></mat-row>
</mat-table>
<mat-paginator #paginator
[pageSize]="10"
[pageSizeOptions]="[5, 10, 20]">
</mat-paginator>
</div>
分页组件：
import {Component, ViewChild} from '@angular/core';
import {MatPaginator, MatTableDataSource} from '@angular/material';
/**
* @title Table with pagination
*/
@Component({
selector: 'table-pagination-example',
styleUrls: ['table-pagination-example.css'],
templateUrl: 'table-pagination-example.html',
})
export class TablePaginationExample {
displayedColumns = ['position', 'name', 'weight', 'symbol'];
dataSource = new MatTableDataSource<Element>(ELEMENT_DATA);
@ViewChild(MatPaginator) paginator: MatPaginator;
/**
* Set the paginator after the view init since this component will
* be able to query its view for the initialized paginator.
*/
ngAfterViewInit() {
this.dataSource.paginator = this.paginator;
}
}
export interface Element {
name: string;
position: number;
weight: number;
symbol: string;
}
const ELEMENT_DATA: Element[] = [
{position: 1, name: 'Hydrogen', weight: 1.0079, symbol: 'H'},
{position: 2, name: 'Helium', weight: 4.0026, symbol: 'He'},
{position: 3, name: 'Lithium', weight: 6.941, symbol: 'Li'},
{position: 4, name: 'Beryllium', weight: 9.0122, symbol: 'Be'},
{position: 5, name: 'Boron', weight: 10.811, symbol: 'B'},
{position: 6, name: 'Carbon', weight: 12.0107, symbol: 'C'},
{position: 7, name: 'Nitrogen', weight: 14.0067, symbol: 'N'},
{position: 8, name: 'Oxygen', weight: 15.9994, symbol: 'O'},
{position: 9, name: 'Fluorine', weight: 18.9984, symbol: 'F'},
{position: 10, name: 'Neon', weight: 20.1797, symbol: 'Ne'},
{position: 11, name: 'Sodium', weight: 22.9897, symbol: 'Na'},
{position: 12, name: 'Magnesium', weight: 24.305, symbol: 'Mg'},
{position: 13, name: 'Aluminum', weight: 26.9815, symbol: 'Al'},
{position: 14, name: 'Silicon', weight: 28.0855, symbol: 'Si'},
{position: 15, name: 'Phosphorus', weight: 30.9738, symbol: 'P'},
{position: 16, name: 'Sulfur', weight: 32.065, symbol: 'S'},
{position: 17, name: 'Chlorine', weight: 35.453, symbol: 'Cl'},
{position: 18, name: 'Argon', weight: 39.948, symbol: 'Ar'},
{position: 19, name: 'Potassium', weight: 39.0983, symbol: 'K'},
{position: 20, name: 'Calcium', weight: 40.078, symbol: 'Ca'},
];
如何实现服务器端分页，这将触发下一页点击的更改事件或页面大小更改以获取下一组记录。
