我对PrimeNG的DataTable有疑问。在我之前的问题中,有人鼓励我使用rowexpansion
作为我的桌子 - 我检查了它,它完全符合我的app概念。但是,我无法使其正常工作 - 我无法扩展行。我在模板中尝试了很多概念,但没有任何帮助。
我认为问题出在<ng-template let-vehicles pTemplate="rowexpansion">
行,但我可能错了。
简化代码:
vehicle.component.ts
export class VehicleComponent implements OnInit {
cols: any[];
ngOnInit() {
this.cols = [
{ field: 'vehicle_id', header: "Vehicle ID" },
{ field: 'dallassettings', header: 'Dallas settings' },
{ field: 'dallasupdated', header: 'Dallas updated' },
{ field: 'dallas_list', header: 'Dallas list' }
];
public vehicles: GeneralVehicle[];
constructor(private vehicleService: VehicleService, private router: Router) {
this.vehicleService.getVehicle().subscribe(vehicle => {
this.vehicles = vehicle;
});
}
interface GeneralVehicle {
status: number;
dallases: Vehicle[];
}
interface Vehicle {
vehicle_id: number;
dallassettings: string;
dallasupdated: string;
dallas_list: DallasList[];
}
interface DallasList {
number: number;
auth: number;
}
vehicle.service.ts
export class VehicleService {
private defUrl = 'dummy.url';
constructor(private http: Http) { }
getVehicle(username?: string, password?: string) {
const url = (!username || !password) ? this.defUrl : 'dummy.url' + username + '/' + Md5.hashStr(password);
return this.http.get(url)
.map(res => res.json());
模板
<div *ngIf="vehicles">
<p-dataTable [value]="vehicles.dallases" expendableRows="true">
<p-header>List of vehicles</p-header>
<p-column expander="true" styleClass="col-icon"></p-column>
<!--<p-column *ngFor="let col of cols" [field]="col.field" [header]="col.header"></p-column>-->
<p-column field="vehicle_id" header="Vehicle ID" [sortable]="true"></p-column>
<p-column field="dallassettings" header="Dallas settings" [sortable]="true"></p-column>
<p-column field="dallasupdated" header="Dallas updated" [sortable]="true"></p-column>
<p-column field="dallas_list" header="Dallas list" [sortable]="true"></p-column>
<ng-template let-vehicles pTemplate="rowexpansion">
<div class="ui-grid ui-grid-responsive ui-fluid" style="font-size:16px;padding:20px">
<div class="ui-grid-row">
<div class="ui-grid-col-9">
<div class="ui-grid ui-grid-responsive ui-grid-pad">
<div class="ui-grid-row">
<div class="ui-grid-col-2 label">Number: </div>
<div class="ui-grid-col-10">{{vehicles.dallas_list.number}}</div>
</div>
<div class="ui-grid-row">
<div class="ui-grid-col-2 label">Auth: </div>
<div class="ui-grid-col-10">{{vehicles.dallas_list.auth}}</div>
</div>
</div>
</div>
</div>
</div>
</ng-template>
</p-dataTable>
</div>
JSON
{
"status": 0,
"dallases": [{
"vehicle_id": 17954,
"dallassettings": "3",
"dallasupdated": "False",
"dallas_list": [{
"number": 666111222,
"auth": 3
}, {
"number": 666777888,
"auth": 4
}, {
"number": 123454321,
"auth": 4
}]
}
}
我希望<p-column expander="true" styleClass="col-icon"></p-column>
能够扩展,并显示特定车辆的数字和身份验证。

使用
<p-dataTable [value]="vehicles.dallases" expandableRows="true">
