How to Get Selected Radio Button Value in React.js?<\/p>\n

React.js is a popular JavaScript library used for building user interfaces. When it comes to forms, React.js provides an easy way to handle user inputs and retrieve their values. If you are working with radio buttons in React.js and want to know how to get the selected radio button value, you’ve come to the right place. In this article, we will explore the steps to achieve this functionality and address some related FAQs.<\/p>\n

To get the selected radio button value in React.js, you can utilize the concept of state. By maintaining the state of the selected radio button, you can access its value whenever needed. Here’s a step-by-step approach to implementing this:<\/p>\n

1. Initialize the state: Start by creating a state variable to hold the value of the selected radio button. You can use the `useState` hook to accomplish this.<\/p>\n

“`javascript
\nimport React, { useState } from ‘react’;<\/p>\n

function RadioButtons() {
\n const [selectedValue, setSelectedValue] = useState(”);<\/p>\n

\/\/ …
\n}
\n“`<\/p>\n

2. Handle radio button selection: Next, define a function that will update the state variable whenever a radio button is selected.<\/p>\n

“`javascript
\nfunction handleRadioChange(event) {
\n setSelectedValue(event.target.value);
\n}
\n“`<\/p>\n

3. Set up radio buttons: Within your component’s render method, create the radio button elements. Make sure to set the `name` attribute to the same value for all radio buttons within a group. Also, provide the `value` attribute to each radio button, which will hold the corresponding value.<\/p>\n

“`javascript
\nfunction RadioButtons() {<\/p>\n

\/\/ …<\/p>\n

return (<\/p>\n
