ok let me give you a hint if you don’t need two-way databinding. In your template you can define a select html element as below

 <ion-select name="periodSelected" ionChange="onChange($event)" >
  <ion-option value="1">Ex1</ion-option>
 <ion-option value="2">Ex2</ion-option>
 </ion-select>

in your component.ts
onChange($event){
console.log($event.target.value);
}

if you do need two-way data binding, then you have to use ngModel.

this is not worked for me. no error it didnt log that event it didnt stop on breakpoint

because ionChange=“onChange($event)” should have (ionChange) need ()

(ionChange)=“onChange($event)”

also

console.log console.log($event.target.value); has error

console.log($event);

it works
