How do you handle events in React?

React simplifies the process of managing and handling events through its use of synthetic events.

Handling Events in React

Synthetic Events

React abstracts browser events into what are known as synthetic events. This ensures a consistent interface across different browsers.

Event Subscription

• When handling events, React behaves consistently across all elements, not just form elements.

• React events use camelCase, unlike HTML, which is helpful for both consistency and avoiding reserved words in JavaScript.

• Use boolean attributes in JSX for default browser events.

Special Event Handling

React provides special interfaces for certain types of events: input components benefit from the value attribute, while media components make use of src or other similar attributes specific to their type.

Code Example: Event Handling

Here is the JavaScript code:

import React from 'react';

class Form extends React.Component {
  constructor(props) {
    super(props);
    this.state = { value: '' };

    this.handleChange = this.handleChange.bind(this);
    this.handleSubmit = this.handleSubmit.bind(this);
  }

  handleChange(event) {
    this.setState({ value: event.target.value });
  }

  handleSubmit(event) {
    alert('A name was submitted: ' + this.state.value);
    event.preventDefault();
  }

  render() {
    return (
      <form onSubmit={this.handleSubmit}>
        <label>
          Name:
          <input type="text" value={this.state.value} onChange={this.handleChange} />
        </label>
        <input type="submit" value="Submit" />
      </form>
    );
  }
}
