推荐答案

您可以绑定单选按钮的数据.只需添加单选按钮的值并在ngModel

You can bind the data of radio button. Just add the value for radio button and change in the ngModel

<input class="form-check-input" type="radio" value="dog" 
[(ngModel)]="dog.value" name="gob" value="i" [checked]="true" 
(change)="onItemChange($event.target.value)"/>

ts

onItemChange(value){
   console.log(" Value is : ", value );
}
