How to control value change in a radio group in React-iCheck?
When working with radio groups in React-iCheck, it is essential to understand how to control changes in the value. React-iCheck provides a convenient way to handle and manipulate the value of radio groups easily. By following a few simple steps, you can effectively control the value change in a radio group.
How to handle value changes in a radio group?
To control the value change in a radio group in React-iCheck, the following steps can be followed:
1. First, install React-iCheck by running the npm command: `npm install react-icheck –save`.
2. Import the required modules in your React component:
“`javascript
import { Radio, RadioGroup } from ‘react-icheck’;
import ‘icheck/skins/all.css’;
“`
3. Define a state property in your component to store the selected value:
“`javascript
state = {
selectedValue: ‘option1’
}
“`
4. Create a handler function to update the state whenever the value changes:
“`javascript
handleChange = event => {
this.setState({ selectedValue: event.target.value });
}
“`
5. In the render method, use the `RadioGroup` component to wrap the radio options, passing the selected value and the change handler function as props:
“`javascript
render() {
return (
value={this.state.selectedValue}
onChange={this.handleChange}
>
);
}
“`
6. Now, whenever a radio option is selected, the `handleChange` function will be called, updating the state with the new selected value.
7. To access the selected value, simply refer to `this.state.selectedValue` within your component.
By following these steps, you can effectively control the value change in a radio group using React-iCheck.
