Sometimes, we run into to the issue where you can’t change checkbox state in React.
In this article, we’ll look at how to fix the issue where you can’t change checkbox state in React.
Fix the Issue Where You Can’t Change Checkbox State in React
To fix the issue where you can’t change checkbox state in React, we should set the checked
prop of the checkbox to a state.
Then we update the state’s value when we check or uncheck the checkbox.
For instance, we write:
import React, { useState } from "react";
export default function App() {
const [checked, setChecked] = useState(false);
return (
<div>
<input
type="checkbox"
checked={checked}
onChange={(e) => setChecked(e.target.checked)}
/>
</div>
);
}
We create the checked
state with the useState
hook.
Then we set the checked
state as the value of the checked
prop to make the checkbox update as the state changes.
Finally, to change the state when we click on the checkbox, we set the onChange
prop of it to a function that calls setChecked
with e.target.checked
to update the checked
state with the checked value of the checkbox.
Therefore, when we check or uncheck the checkbox, we should see that displayed on the screen.
Conclusion
To fix the issue where you can’t change checkbox state in React, we should set the checked
prop of the checkbox to a state.
Then we update the state’s value when we check or uncheck the checkbox.
