How to get value from radio button in React.js?<\/p>\n

React.js is a popular JavaScript library widely used for building user interfaces. When it comes to handling form inputs, radio buttons are a common choice for selecting options from a predefined set. In React, obtaining the selected value from a radio button can be accomplished in a straightforward manner. In this article, we will explore the steps to retrieve the value of a radio button in React.js and also address some related frequently asked questions.<\/p>\n

To begin, the most crucial aspect to consider is that radio buttons in React should be placed within a form component. This allows us to take advantage of the built-in form handling capabilities that React provides. Once the radio buttons are appropriately placed within a form, follow these steps to retrieve the selected value:<\/p>\n

1. Create a state variable in your component to store the selected value. You can use the `useState` hook to accomplish this.<\/p>\n

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

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

\/\/ …
\n}
\n“`<\/p>\n

2. Assign the `selectedValue` state variable to the `value` prop of each radio button.<\/p>\n

“`jsx
\n\n type=”radio”
\n value=”option1″
\n checked={selectedValue === ‘option1’}
\n onChange={() => setSelectedValue(‘option1’)}
\n\/>
\n“`<\/p>\n

3. Handle the `onChange` event of each radio button, updating the `selectedValue` state variable accordingly.<\/p>\n

“`jsx
\nconst handleChange = (event) => {
\n setSelectedValue(event.target.value);
\n};<\/p>\n

\/\/ …<\/p>\n

\n type=”radio”
\n value=”option1″
\n checked={selectedValue === ‘option1’}
\n onChange={handleChange}
\n\/>
\n“`<\/p>\n

**And that’s it! By following these steps, you can easily retrieve the selected value from a radio button in React.js.**<\/p>\n

Now, let’s address some frequently asked questions related to obtaining a value from a radio button in React.js:<\/p>\n
