Trouble with selectionChange event in mat-select component in Angular 13

I'm having trouble getting the selectionChange event to fire in my mat-select when the value is changed.

html file

<mat-select (selectionChange)="changeCategory()">
                    <mat-option *ngFor="let category of categoryList" [value]="category._id">{{category.name}} </mat-option> </mat-select>

ts file

changeCategory(){
    console.log('ok')
  }

Answer №1

Ensure you have imported the MatSelectModule in your app.module.ts file.

Answer №2

In order to assist you better, I have created a functional demonstration showcasing the implementation of the selectionChange feature. This will allow you to compare it against your own scenario and identify any missing elements: view demo

Each time a selection is made, a number within the template incrementally increases by 1 to indicate that the event has been triggered. I trust this resource will provide valuable insight for you.

Answer №3

<mat-select
            (selectionChange)="chooseOption($event)"
            required
            formControlName="buyer"
          >

Feel free to experiment with this approach

chooseOption(event) {
    console.log(event.value);
    // let value = event.
  }
