Radio

The Radio component lets you render a set of mutually-exclusive options in your UI, where only one choice can be selected at a time. Under the hood it uses Solid’s context API and it works in conjunction with the Radio.Button slot.

For more information about the Radio.Button slot, check out the Radio.Button documentation.

To create a radio options in your UI, you need to wrap the Radio.Button slots with the Radio component.

import Radio from '@components/Basic/RadioGroup/Radio';
const App = () => {
return (
<>
<Radio>
<Radio.Button selected value="red">red</Radio.Button>
<Radio.Button value="green">green</Radio.Button>
<Radio.Button value="blue">blue</Radio.Button>
</Radio>
</>
);
};
export default App;

Retrieve the value of the selected option when it changes

Section titled “Retrieve the value of the selected option when it changes”

To retrieve the value of the selected option:

  • Use the onChange prop to respond when the selected option changes
  1. Provide a callback to the onChange prop to respond to state changes.
  2. Inside the callback, access the selected option’s value via the selected argument.
import Radio from '@components/Basic/RadioGroup/Radio';
const App = () => {
const getValue = (selected: string) => {
console.log(selected);
}
return (
<>
<Radio onChange={getValue}>
<Radio.Button selected value="red">red</Radio.Button>
<Radio.Button value="green">green</Radio.Button>
<Radio.Button value="blue">blue</Radio.Button>
</Radio>
</>
);
};
export default App;

The Radio component lets you set the selected option through code.

  1. Declare a ref variable with type RadioRef and pass it to the Radio component.
  2. Call ref.changeOption() from anywhere (e.g., a keyboard event or external button) to set a new selected option programmatically.
import Radio, { RadioRef } from '@components/Basic/RadioGroup/Radio';
const App = () => {
let RadioRef!: RadioRef;
const handleKeyPress = (e: KeyboardEvent) => {
if (e.keyCode !== 13) return
RadioRef.changeOption('green');
}
return (
<>
<Radio ref={RadioRef} keypress={handleKeyPress}>
<Radio.Button selected value="red">red</Radio.Button>
<Radio.Button value="green">green</Radio.Button>
<Radio.Button value="blue">blue</Radio.Button>
</Radio>
</>
);
};
export default App;
