How to get the value of checkbox using a ref in React?
To get the value of checkbox using a ref in React, we can use the checked property of the checkbox.
For instance, we write:
import React, { useRef } from "react";
export default function App() {
const checkboxRef = useRef();
const save = () => {
console.log(checkboxRef.current.checked);
};
return (
<div>
<div>
<label>
<input type="checkbox" ref={checkboxRef} /> Check me out
</label>
</div>
<button onClick={save}>Submit</button>
</div>
);
}
We create the checkboxRef with the useRef hook.
Then we assign the ref prop to checkboxRef to assign the checkbox as the value of checkboxRef.current.
Next, we define the save function to logged the checked value of the checkbox, which is stored in checkboxRef.current.checked.
Finally, we assign the onClick prop of the button to the save function to run it when we click it.
Therefore, when we check or uncheck the checkbox and click Submit, we should see the checked value logged.
Conclusion
To get the value of checkbox using a ref in React, we can use the checked property of the checkbox.
