Question

What is the best way to retrieve the value from a chosen radio button?

Here is the HTML code snippet:

    <ion-list radio-group [(ngModel)]="portion" (ionChange)="getPortionType()">
        <ion-list-header>
            Select Portion
        </ion-list-header>
        <ion-item *ngFor="let item of portionList">
            <ion-label>{{item.portion}}
                <p>{{item.price}} ₺</p>
            </ion-label>
            <ion-radio value="{{item.id}}"></ion-radio>
        </ion-item>
        <button *ngIf="portion != ''" ion-button block (click)="proceedToNextStep()">Proceed</button>

    </ion-list>

You can see that I am using [(ngModel)] = "portion". When I retrieve this value, only the record ID is available. However, I want to access all the values from the selected radio button.

I specifically need to use {{item.portion}} and {{item.price}}. Please guide me on how to utilize these values in the .ts file.

Thank you for your help!

All you need to do is create a method or function that will be triggered when a radio button event occurs. I hope this clarifies things for you.

.html

 <ion-item *ngFor="let item of porsiyonlar">
     <ion-label>{{item.porsiyon}}
          <p>{{item.fiyat}} ₺</p>
     </ion-label>
     <ion-radio value="{{item.id}}" (change)="onItemChange($event)"></ion-radio>
 </ion-item>

.ts

   console.log("The value is: ", value);
}

To retrieve the chosen item from the 'porsiyonlar' array, you can utilize the id and find method.

getPortionType() {
 const selectedItem = this.porsiyonlar.find(i => i.id === this.porsiyon);
 console.log(selectedItem.porsiyon,selectedItem.fiyat);
}

Alternatively, you can attach a value directly to the object itself.

<ion-radio [value]="item"></ion-radio>

Component

getPortionType() {
 console.log(this.porsiyon.porsiyon, this.porsiyon.fiyat, this.porsiyon.id);
}

 The code snippet provided filters through 'porsiyonlar' array to find a matching id with 'porsiyon'. Once found, it assigns the corresponding 'porsiyonadi' value. A successful implementation, thanks to everyone who contributed.

This solution is correct, my gratitude to all involved
