这是Angular2模板：
<paper-dropdown-menu label="Country">
<paper-listBox class="dropdown-content" [(ngModel)]="selectedCountry" (ngModelChange)="GetAdmin1s($event)">
<paper-item *ngFor="let country of countries" value="{{country.Id}}">{{country.Name}}</paper-item>
</paper-listBox>
</paper-dropdown-menu>
我收到此错误：
"Template parse errors:
Property binding ngFor not used by any directive on an embedded template (""dropdown-content" [(ngModel)]="selectedCountry" (ngModelChange)="GetAdmin1s($event)">
[ERROR ->]<paper-item *ngFor="let country of countries" value="{{country.Id}}">{{country.Name}}</paper-item>
"): LocationComponent@4:12
Property binding ngForCountry not used by any directive on an embedded template (""dropdown-content" [(ngModel)]="selectedCountry" (ngModelChange)="GetAdmin1s($event)">
[ERROR ->]<paper-item *ngFor="let country of countries" value="{{country.Id}}">{{country.Name}}</paper-item>
"): LocationComponent@4:12"
国家变量定义为：
public countries: Array<Country> = [];
我使用ngFor有什么问题？为什么要寻找ngForCountry？
解决方法
@H_404_30@ 试试可能有帮助<paper-dropdown-menu label="Country">
<paper-listBox class="dropdown-content" [(ngModel)]="selectedCountry" (ngModelChange)="GetAdmin1s($event)">
<paper-item ngFor #country [ngForOf]="countries" value="{{country.Id}}">{{country.Name}}</paper-item>
</paper-listBox>
</paper-dropdown-menu>
