How to Get the Value of the Selected Ion Radio Button After Submission in Angular

Dealing with form submissions in Angular can be tricky, especially when trying to retrieve the selected values from radio buttons. In this post, we’ll walk you through the steps to correctly get the value of the selected ion radio button after submission. If you are using Ionic Framework with Angular, this guide is for you!

Understanding Radio Buttons in Angular

Radio buttons are a common way for users to select one option from a small set of choices. When integrating radio buttons in an Angular application, you must ensure that the selected value is bound correctly.

Problem Setup

Let's say we have a simple questionnaire with multiple choice options. Our Angular component is set up with a radio button group, and we want to fetch the value selected by the user upon submission.

Here’s the initial structure of our code:

The Solution

To effectively capture the value from the selected radio buttons, we can simplify our binding using Angular’s two-way data binding feature with ngModel. Here’s how to modify your code:

Step 1: Change the ion-radio-group Binding

Instead of using [value], you should implement [(ngModel)]. This will allow Angular to keep track of the selected value:
