In this article, we would like to show you how to handle a mouse click event on div element in React.

Below example uses:

  • the component's state to store color value,
  • setState() method to update the color,
  • onClick property to handle the event.

Practical example:

// ONLINE-RUNNER:browser;

// Note: Uncomment import lines during working with JSX Compiler.
// import React from 'react';
// import ReactDOM from 'react-dom';

class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      color: 'yellow'
    };
  }
  handleClick = () => {
    this.setState({ color: this.state.color === 'yellow' ? 'orange' : 'yellow' });
  };
  render = () => {
    return (
      <div style={{ background: this.state.color }} onClick={this.handleClick}>
        Click me to change my color.
      </div>
    );
  };
}

const root = document.querySelector('#root');
ReactDOM.render(<App />, root);
