导读:我收到此错误 – “模板解析错误:NgControl没有提供者” The error comes from this line of code -- select (ngModel)="currencies" (ngModelChange)="showPurchase($event)" class="annka-center" name="curencies" option *ngFor="let money of currenci
我收到此错误 – “模板解析错误:NgControl没有提供者”
The error comes from this line of code --> <select (ngModel)="currencies" (ngModelChange)="showPurchase($event)" class="annka-center" name="curencies"> <option *ngFor="let money of currencies; let i = index" (ngValue)="money" (click)="showPurchase(money)"> {{money.Currency}} </option> </select> 上面的代码工作顺利,直到我将ReactiveFormsModule添加到我的应用程序. 我在这里尝试了解决方案 ERROR in : No provider for NgControl Angular AOT 但这对我没有用.我正在使用Angular 4. 解决方法
应该
<select [(ngModel)]="currencies" (ngModelChange)="showPurchase($event)" class="annka-center" name="curencies"> <option *ngFor="let money of currencies; let i = index" (ngValue)="money" (click)="showPurchase(money)"> {{money.Currency}} </option> </select> 还要确保在导入下的app.module.ts中导入FormsModule @NgModule({ imports: [ FormsModule ] (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
