Use ngModel for that maybe, it’s what you want ?

Checkbox doc with ngModel

@Dlazzy i am using ngModel but its not getting the values of all selected checkboxes. Moreover how can i restore multiple values in 1 ngModel.

But for now your code does not add already ‘selected’ checkbox ?

modify your ion-checkbox like this:

<ion-checkbox *ngIf="tost.qotext != ''" (ionChange)="getChanged(tost.qotext)" ></ion-checkbox>

And then in your ts file:

export class DemoPage{
  selectedCheckbox: any;
  constructor() {
  this.selectedCheckbox = {};
  }
  
  getChanged(e){
    if(!this.selectedCheckbox[e])
    {    
      this.selectedCheckbox[e] = true;
    }
    else{
      this.selectedCheckbox[e] = false;
    }
    console.log(this.selectedCheckbox);
  }
}

You’ll get all your selected checkbox in json with true value.( check variable this.selectedCheckbox)
