我来回阅读文档,但没有找到关于该基本功能的任何消息。
这是我到目前为止所得到的:
ngOnInit() {
this.rowData = this.paymentMethodService.getPaymentMethods({});
}
从Observable获取数据,请注意空白的{}
,这是我希望在其中传递过滤器,排序和分页信息的地方。
这是一个已定义的过滤器
{ headerName: 'Name', field: 'name' , sortable: true, filter: 'agTextColumnFilter' }
过滤器仅应用于最初显示的那些行,而我需要将其数据路径到服务器。

您需要将有关filter
和sorting
的信息发送到您的API。这是一个粗糙的例子:
<ag-grid-angular
style="width: 100%; height: 100%"
class="ag-theme-balham"
[gridOptions]="gridOptions"
[columnDefs]="yourColumns"
(gridReady)="onGridReady($event)"
#grid
></ag-grid-angular>
TypeScript:
public yourColumns: any[];
public rowData: any[];
public gridOptions: any;
@ViewChild('grid') grid: AgGridNg2;
this.yourColumns= [
{ headerName: 'One', field: 'one' },
{ headerName: 'Two', field: 'two' },
{ headerName: 'Three', field: 'three' }
];
this.gridOptions = {
rowSelection: 'single',
cacheBlockSize: 100,
maxBlocksInCache: 2,
enableServerSideFilter: false,
enableServerSideSorting: false,
rowModelType: 'infinite',
pagination: true,
paginationAutoPageSize: true
};
private getRowData(startRow: number, endRow: number): Observable<any[]> {
//this code is included only for example. You need to move it to
//service
let params: HttpParams = new HttpParams()
.append('startRow', `${startRow}`)
.append('endRow', `${endRow}`);
return this.http.get(`${this.actionUrl}/GetAll`, {params: params})
.pipe(
map((res: any) => res.data)
);
}
onGridReady(params: any) {
console.log("onGridReady");
var datasource = {
getRows: (params: IGetRowsParams) => {
this.getRowData(params.startRow, params.endRow)
.subscribe(data => params.successCallback(data));
}
};
params.api.setDatasource(datasource);
}
