Adding Event Handlers in JSX

Learn how to add event handlers in JSX. A step-by-step guide to understanding and implementing event handlers in React's JSX syntax.

( tag: react, tag: jsx, tag: event handlers )

To add event handlers in JSX, we utilize camelCase syntax rather than lowercase. Let’s consider a button click event. In plain JavaScript, it would look like this:

<button onclick="activateFunction()">Click Me!</button>

In React’s JSX, we modify it to:

<button onClick={activateFunction}>Click Me!</button>

Here activateFunction is a function defined in your component. Remember, in JSX, you pass a function as the event handler, rather than a string.

Event handlers in React are attached directly to components and, when using class components, typically trigger methods. This is slightly different from assigning events to DOM in HTML.

class MyComponent extends React.Component {
  activateFunction() {
    // your code here
  }

  render() {
    return <button onClick={this.activateFunction}>Click Me!</button>
  }
}

Note: Make sure to bind your methods in class components to access this.
