How to Fix a Checkbox not Emitting the Change Event in React?

Sometimes, we may encounter the issue where a checkbox not emitting the change event when we’re developing a React app.

In this article, we’ll look at how to fix the issue where a checkbox not emitting the change event when we’re developing a React app.

Fix a Checkbox not Emitting the Change Event in React

To fix the issue where a checkbox not emitting the change event when we’re developing a React app, we should get the checked value of the checkbox by setting the onChange prop to a function that gets the checked value of the checkbox.

Then we can set the checkbox value by setting the checkbox to a state that’s set to the checked value of the checkbox.

For instance, we can write:

import { useState } from "react";

export default function App() {
  const [active, setActive] = useState(false);
  return (
    <div className="App">
      <input
        type="checkbox"
        checked={active}
        onChange={(e) => setActive(e.target.checked)}
      />
    </div>
  );
}

to set the onChange prop to a function that calls the setActive function with e.target.checked to set the active state to the checked value of the checkbox.

Then we set the checked prop to the value of the active state to make the checkbox update with the checked value of the active state.
