Creating a custom radio-group button in Ionic using ngFor to dynamically display options and capture user selections in TypeScript

API endpoint

XHTML

<form (ngSubmit)="submitNetworkingForm()">
     <div  *ngFor="let item of networkingdata; let i = index;" >
                           <ion-list  *ngFor="let inner of item; let b = index;" radio-group [(ngModel)]="answers" name="answers" >
                                   <ion-label>{{b}} . {{inner[i][b].question}}</ion-label>
                                      <ion-item   *ngFor="let innermost of inner[i]; let c = index;">
                                        <ion-label> {{innermost.answer}}</ion-label>
                                        <ion-radio  [value]="innermost.answer"></ion-radio>
                                      </ion-item>

                            </ion-list>
                    </div>

                <button ion-button type="submit">Submit</button>
    </form>

I am exploring a way to create a flexible model. Consider this example in PHP:

echo '<input type="radio" name="salutation_description[]" value="'.$row1[0].'"/>'  

which could then be used in TypeScript.

Answer №1

This block of code has been optimized by removing [(ngModel)]="answers" from it, resulting in smooth performance

<ion-list  *ngFor="let inner of item; let b = index;" radio-group name="answers" >
