In this example, i will show you react radio button onchange event example. if you want to see example of react radio buttons example then you are a right place. we will help you to give example of react radio button group example. it's simple example of how to implement radio button in react.

If you are new in react js then you want to see how to use radio button in react app. but it's very easy to use radio button input in react js app. you can use it as you use in html and you have to write change event on it. using that change event you have to store value into form state. so you can get that data on submit.

So, let's see bellow preview and code:

Example Code:

import React, { Component } from 'react';

import { render } from 'react-dom';

class App extends Component {

constructor() {

super();

this.state = {

gender: ''

};

this.handleChange = this.handleChange.bind(this);

this.handleSubmit = this.handleSubmit.bind(this);

}

handleChange(event) {

this.setState({gender: event.target.value});

}

handleSubmit(event) {

console.log(this.state);

event.preventDefault();

}

render() {

return (

<div>
