Redirecting to another web page on selecting an option in drop down box

Hello!
I want to redirect to another page when i select an option in drop down box in ionic.
I have tried different possibilities but nothing seems to work
Can you help me out with this…
I want it in 2 methods.

  1. passing a parameter while pushing to another page
  2. passing a value to service and getting back from service.
    Im happy if even 1 method works
    Thanks in advance :slightly_smiling_face:

This method work, but i no have certain if is the best method!

First you call a method when you select anything, this method is called in (ionSelect)="onChange(example)"

<ion-item>
  <ion-label floating>Example</ion-label>
   <ion-select name="example" [(ngModel)]="example" [ngModelOptions]="{standalone: true}">
      <ion-option [value]="example"  item-left (ionSelect)="onChange(example)"></ion-option>
      <ion-label>{{Example}}</ion-label>
   </ion-select>
</ion-item>

After select one option onChange is called

onChange(){
  if(this.example == expected){
   this.navCtrl.push(goToPageExpected);
 }
}

If this value has expected, you’re redirect for other page.
