    Post a clear and complete question, and post the relevant code in the question itself, as properly formatted text. Not as a link to an image.

Use like this.



<select (change)="onChange($event.target.selectedIndex)">
<option *ngFor="let item of items; let i=index;" [value]="item.value">{{item.value}}</option>




Component:



onChange(index){
console.log(index);
}
