The changed it from change to selectionChange.

<mat-select (change)="doSomething($event)">

<mat-select (selectionChange)="doSomething($event)">

Answer 2

If you're using Reactive forms you can listen for changes to the select control like so..

this.form.get('mySelectControl').valueChanges.subscribe(value => { ... do stuff ... })

Answer 3

For me (selectionChange) and the suggested (onSelectionChange) didn't work and I'm not using ReactiveForms. What I ended up doing was using the (valueChange) event like:

<mat-select (valueChange)="someFunction()">

And this worked for me

Answer 4

For:

1) mat-select (selectionChange)="myFunction()" works in angular as:

sample.component.html

 <mat-select placeholder="Select your option" [(ngModel)]="option" name="action" 
      (selectionChange)="onChange()">
     <mat-option *ngFor="let option of actions" [value]="option">
       {{option}}
     </mat-option>
 </mat-select>

sample.component.ts

actions=['A','B','C'];
onChange() {
  //Do something
}

2) Simple html select (change)="myFunction()" works in angular as:

sample.component.html

<select (change)="onChange()" [(ngModel)]="regObj.status">
    <option>A</option>
    <option>B</option>
    <option>C</option>
</select>

sample.component.ts

onChange() {
  //Do something
}
