angular - 为循环中的每个 添加 ngx-bootstrap 的弹出窗口

Question

我正在尝试使用带有来自循环变量的数据的模板来显示弹出窗口，但我遇到了这些错误:

There is no directive with "exportAs" set to "bs-popover" ("template>
                      <span [popover]="popTemplate" popoverTitle="Anomalies" triggers="" [ERROR ->]#pop="bs-popover"></span>
                      <span *ngIf="vehicle.anomalies.length > 0" class="ba"): ng:///VehiclesModule/VehiclesSearchComponent.html@61:89
Can't bind to 'popover' since it isn't a known property of 'span'. ("
                        </ul>
                      </ng-template>
                      <span [ERROR ->][popover]="popTemplate" popoverTitle="Anomalies" triggers="" #pop="bs-popover"></span>
             "): ng:///VehiclesModule/VehiclesSearchComponent.html@61:28
Error: Template parse errors:

                      <span [ERROR ->][popover]="popTemplate" popoverTitle="Anomalies" triggers="" #pop="bs-popover"></span>
             "): ng:///VehiclesModule/VehiclesSearchComponent.html@61:28

我的组件 HTML 是这样的:

<table class="table table-bordered table-striped table-sm table-hover">
                <thead>
                  <tr>
                    <th>
                      <input #chkAll type="checkbox" (click)="selectAll(chkAll.checked)" />
                    </th>
                    <th>Chassis</th>
                    <th>Última Atualização</th>
                    <th>MVS</th>
                    <th>Pátio</th>
                    <th>Localização</th>
                    <th class="actions-col-2"></th>
                  </tr>
                </thead>
                <tbody>
                  <tr *ngFor="let vehicle of vehicles; let idx = index">
                    <td>
                      <input type="checkbox" id="vehicle-{{vehicle.id}}" name="vehicle-select" [(ngModel)]="vehicles[idx].checked" value="{{vehicle.id}}"
                      />
                    </td>
                    <td>{{vehicle.chassis}}</td>
                    <td>{{vehicle.lastUpdate || '' | amFromUtc | amDateFormat: 'DD/MM/YYYY'}}</td>
                    <td>{{vehicle.mvsDescription}}</td>
                    <td>{{vehicle.yard.description}}</td>
                    <td>{{vehicle.location}}</td>
                    <td>

                      <ng-template #popTemplate>
                        <ul *ngFor="let anomaly of vehicle.anomalies">
                          <li>
                            <b>Componente:</b> {{anomaly.componentId}}
                            <b>Posição:</b> {{anomaly.tesisPosition}}
                            <b>Defeito:</b> {{anomaly.tesisDefect}}</li>
                        </ul>
                      </ng-template>
                      <span [popover]="popTemplate" popoverTitle="Anomalies" triggers="" #pop="bs-popover"></span>
                      <span *ngIf="vehicle.anomalies.length > 0" class="badge badge-pill badge-danger" (mouseenter)="pop.show()" (mouseleave)="pop.hide()">{{vehicle.anomalies.length}}</span>

                  </tr>

                </tbody>
              </table>

PS:我已经将 PopoverModule 添加到 AppModule 的导入中。

Answer 1

确保将 PopoverModule 导入到声明了 VehiclesSearchComponent 的模块中。

@NgModule({
    // ...
    imports: [PopoverModule], <----
    declarations: [VehiclesSearchComponent],
})
export class NameModule {
}
