代码如下.
<input [(ngModel)]="model.brand" [typeahead]="model.brands" ng-model-options="{'updateOn': 'blur'}"
(typeaheadOnSelect)="brandOnSelect($event)" (typeaheadNoResults)="brandNoResults($event)"
[typeaheadOptionField]="'Value'" class="form-control" ngcontrol="brand" >
<div *ngIf="brand.dirty && !brand.valid ">
<p *ngIf="brand.errors.required" class="text-help">{{ required }}</p>
</div>
解决方法
您在输入上错过了“name”属性,这是正确使用ngModel所必需的.
