我试图在点击分页时调用 API。最初,我静态设置了长度,它工作正常。我能够进行分页 API 调用。然后我也尝试动态设置长度并且它也可以工作,但后来它停止工作。请帮我指出我的错误。我正在 this.totalEmp 中设置内容的长度,并且也能够在 html 端打印它,但是当我尝试在 mat-paginator 中设置 [length] 时。它对我不起作用。我也尝试在 mat-paginator 中设置#paginator,但没有看到任何变化。
Below is my implementation
**HTML:**
<mat-paginator
[length]="totalEmp"
[hidden]="normalPagination"
[pageSize]="2"
[pageSizeOptions]="[2]"
[pageIndex]="pageIndex"
(page)="pageEvent = getDataByPagination($event)"></mat-paginator>
**.ts file Code**
export class EmpComponent implements OnInit {
dataSource: any;
totalEmp: number=0;
normalPagination: boolean;
@ViewChild(MatPaginator, { static: true }) paginator: MatPaginator;
@ViewChild(MatSort, { static: true }) sort: MatSort;
ngOnInit() {
this.getTableContentCount();
}
getTableContentCount() {
this.myService.CountService().subscribe(
(response: any) => {
if (response) {
this.totalEmp = response;
this.getServerData(0,this.totalEmp);
}
},
(error: any) => { }
);
}
public getDataByPagination(event?: PageEvent) {
this.myService.getPaginationService(event).subscribe(
response => {
if (response) {
this.showLoader=true;
this.normalPagination=false;
this.total = this.totalEmp;
this.allData=response;
this.dataSource = new MatTableDataSource(this.allData);
this.dataSource.paginator = this.paginator;
this.dataSource.sort = this.sort;
this.showLoader=false;
}
},
error => {
// handle error
}
);
return event;
}
