我希望表格具有分页功能,以便用户可以转到首选页面并重新排列要显示的页面,就像这样:
这是我到目前为止所拥有的:
HTML
<div class="mat-elevation-z8">
<table cellspacing='2' cellpadding='40' mat-table [dataSource]="dataSource" matSort>
<!--Tv Posters-->
<ng-container matColumnDef="poster">
<th mat-header-cell *matHeaderCellDef mat-sort-header> Poster </th>
<td mat-cell *matCellDef="let row">
<img
*ngIf="row.poster_path"
class="thumbnail"
src="http://image.tmdb.org/t/p/w500/{{row.poster_path}}">
</td>
</ng-container>
<!-- Name Column -->
<ng-container matColumnDef="name">
<th mat-header-cell *matHeaderCellDef mat-sort-header> Name </th>
<td mat-cell *matCellDef="let row"> {{row.name}} </td>
</ng-container>
<!-- ID Column -->
<ng-container matColumnDef="id">
<th mat-header-cell *matHeaderCellDef mat-sort-header> Id </th>
<td mat-cell *matCellDef="let row"> {{row.id}} </td>
</ng-container>
<!-- Release date -->
<ng-container matColumnDef="release">
<th mat-header-cell *matHeaderCellDef mat-sort-header> Release</th>
<td mat-cell *matCellDef="let row"> {{row.first_air_date}} </td>
</ng-container>
<!-- Description Column -->
<ng-container matColumnDef="description">
<th mat-header-cell *matHeaderCellDef mat-sort-header> Description </th>
<td mat-cell *matCellDef="let row" [style.color]="row.color"> {{row.overview}} </td>
</ng-container>
<tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
<tr mat-row *matRowDef="let row; columns: displayedColumns;">
</tr>
</table>
<div class="row pagination">
<div class="col page-select">
<div class="label">Go to page:</div>
<mat-form-field>
<mat-select [ngModel]="manualPage" (ngModelChange)="updateManualPage($event)">
<mat-option [value]="1">1</mat-option>
<mat-option [value]="2">2</mat-option>
<mat-option [value]="3">4</mat-option>
<mat-option [value]="5">5</mat-option>
</mat-select>
</mat-form-field>
</div>
<div class="col-md-auto">
<mat-paginator [pageSize]="5" [pageSizeOptions]="[5, 10, 20]">
</mat-paginator>
</div>
</div>
</div>
以下是转到页面的方法:
component.ts
...........
manualPage: null;
...........
updateManualPage(index) {
this.manualPage = index;
this.paginator.pageIndex = index - 1;
}
clearManualPage() {
this.manualPage = null;
}
不幸的是,当我选择一个页面时,例如,我只能重新排列要显示在表格中的页面。 2按照规定没有任何反应。
我在这里做错了什么?有什么建议吗?

尝试这段代码:
<mat-select [(ngModel)]="manualPage" (ngModelChange)="updateManualPage($event)">
<mat-option [value]="1">1</mat-option>
<mat-option [value]="2">2</mat-option>
<mat-option [value]="3">3</mat-option>
<mat-option [value]="4">4</mat-option>
<mat-option [value]="5">5</mat-option>
</mat-select>
请告诉我这是否可行。

我发现该解决方案也许对未来有兴趣
HTML分页部分
<div class="row pagination">
<div class="col page-select">
<div class="label gotoPage">Go to page:</div>
<mat-form-field>
<mat-select [(ngModel)]="manualPage" (ngModelChange)="updateManualPage($event)">
<mat-option [value]="1">1</mat-option>
<mat-option [value]="2">2</mat-option>
<mat-option [value]="3">3</mat-option>
<mat-option [value]="4">4</mat-option>
<mat-option [value]="5">5</mat-option>
</mat-select>
</mat-form-field>
</div>
<div class="col-md-auto">
<mat-paginator
[pageSize]="5"
[pageIndex]='0'
[pageSizeOptions]="[5, 10, 20]"
(page)="clearManualPage()">
</mat-paginator>
</div>
</div>
compo.ts部分
public updateManualPage(index: number): void {
this.manualPage = index;
this.paginator.pageIndex = index;
this.paginator.page.next({
pageIndex: this.paginator.pageIndex,
pageSize: this.paginator.pageSize,
length: this.paginator.length
});
}
public clearManualPage(): void {
this.manualPage = 0;
}
现在转到页面或跳至页面效果很好
