Toggle

OSCC · React, Components, State · Nov 16, 2020

Renders a toggle component.

  • Use the useState() hook to initialize the isToggledOn state variable to defaultToggled.
  • Render an <input> and bind its onClick event to update the isToggledOn state variable, applying the appropriate className to the wrapping <label>.
const Toggle = ({ defaultToggled = false }) => {
  const [isToggleOn, setIsToggleOn] = React.useState(defaultToggled);

  return (
    <label className={isToggleOn ? 'toggle on' : 'toggle off'}>
      <input
        type="checkbox"
        checked={isToggleOn}
        onChange={() => setIsToggleOn(!isToggleOn)}
      />
      {isToggleOn ? 'ON' : 'OFF'}
    </label>
  );
};
.toggle input[type="checkbox"] {
  display: none;
}

.toggle.on {
  background-color: green;
}

.toggle.off {
  background-color: red;
}
ReactDOM.render(<Toggle />, document.getElementById('root'));
