I have a complex object i.e., like below
someName = [
{name: "John",id: "1",rating: ['0', '1', '2', '3', '4', '5']},
{name: "robert", id: "2", rating: ['0', '1', '2', '3', '4', '5']},
{name: "luv", id: "3", rating: ['0', '1', '2', '3', '4', '5']}
];
from which I want to make a questionnaire to make sure they rate their answer from 0-5, now when I'm rendering my html like below
<ng-container *ngFor="let sort of someName; let i=index">
<label id="example-radio-group-label">Rate your favorite section</label>
<mat-radio-group aria-labelledby="example-radio-group-label" class="example-radio-group" [(ngModel)]="sectionRating">
<mat-radio-button class="example-radio-button" *ngFor="let section of sort.sections" [value]="section">{{season}}</mat-radio-button>
</mat-radio-group>
</ng-container>
This is rendering properly but when I select my first question rating as 1 it is also selecting from all other rating also, and also i want to capture these each rating for that i tried [(ngModel)] but its giving only one value instead of an array
in my .ts file, I gave my model reference as Array like this:
sectionRating: any[] = [];
You can try this, use (change) event and then add the click item in the local variable.
HTML Code:
<ng-container *ngFor="let sort of someName; let i=index">
<label id="example-radio-group-label">Rate your favorite section</label>
<br>
{{sort.name}}
<br>
<mat-radio-group aria-labelledby="example-radio-group-label" class="example-radio-group">
<mat-radio-button class="example-radio-button" *ngFor="let section of sort.rating" [value]="section"
(change)="radioChange($event,sort)">
{{section}}</mat-radio-button>
</mat-radio-group>
<br>
<br>
</ng-container>
<h2>Selected Array</h2>
<div>
{{finalArray | json }}
</div>
TS Code:
import { Component } from '@angular/core';
import { MatRadioChange } from '@angular/material';
// ...
/**
* @title Basic radios
*/
@Component({
selector: 'radio-overview-example',
templateUrl: 'radio-overview-example.html',
styleUrls: ['radio-overview-example.css'],
})
export class RadioOverviewExample {
someName = [
{ name: "John", id: "1", rating: ['0', '1', '2', '3', '4', '5'] },
{ name: "robert", id: "2", rating: ['0', '1', '2', '3', '4', '5'] },
{ name: "luv", id: "3", rating: ['0', '1', '2', '3', '4', '5'] }
];
finalArray: any[] = [];
radioChange(event: MatRadioChange, data) {
var obj = this.someName.filter(x => x.id == data.id)[0];
obj.selected = event.value;
if (!this.finalArray.some(x => x.id == data.id)) {
this.finalArray.push(obj);
}
}
}
